Good morning, this is Let’s Talk Dentistry. I am Dr. Marvin, thank you for joining me today. For the next 25 minutes, we’re going to talk about dentistry. That’s right, we talk about dentistry. For the last few years we’ve talked about dentistry every Saturday morning around this time. Hopefully this is not your first time; you’re a repeat listener, and you join me because you want to learn something new. That’s what we do. I am the owner and one of the dentists at The Center for Natural Dentistry, an office here in San Diego that offers a different approach to dentistry, a more health-oriented approach, an approach that’s more common sense. We like to think that we’re doing the best dentistry around. That’s right, dentistry should be about the best dentistry for your health, not for your teeth. That’s what I talk about every single week.

If you want to schedule an appointment with us, you’ll want to call the telephone number at our office. That’s 760-536-1199. Another way to learn more about what we do is to go to our website. That’s If you are on facebook, look us up. The Center for Natural Dentistry.

Last week we talked a lot about certain things that you should look for certain things that you should look for in a dentist. I have a lot of people who ask me to refer them to a dentist in their area. Unfortunately, there aren’t many dentists who do what I do. Since there aren’t many dentists, I can’t really refer people to anyone. I did offer some tips on what to look for and what to ask. A lot of people just don’t know what questions to ask. If you missed last week’s show, go to our website or just tune in every single week. Maybe I’ll repeat a lot of the topics that I have previously talked about.

Let’s talk about today’s show. Today I wan to talk about toxic dental materials. This is a topic that you’re not going to get to talk with your dentist about, either because they don’t want to talk to you about it, because they don’t know about it, or they don’t have time to talk to you about it. That’s one thing I talked about last week. When you’re talking to your dentist, ask them good questions and see how they respond. If they respond like, ‘You don’t know what you’re talking about, that’s fine. Listen to my answer, and then that’s it. Let’s move forward with the treatment.’ That’s not the type of dentist you probably want to be with. You need to ask the right questions first, and that’s what that show was about.

Today we’re going to talk about toxic dental materials and some questions that you may want to ask your dentists, and also some bottom line statements that are really going to blow the socks off. Let’s talk about plastic fillings. Other names for plastic fillings could be composite fillings or resin fillings. These are white colored or tooth colored fillings. They have lots of different shades. There are a lot of different manufacturers out there making these. There are literally thousands of different types of these white, plastic fillings. There is another category of white fillings called glass ionomers. They just really haven’t caught on. We don’t use them in our office. They have a lot of fluoride in them, and one of the things we don’t believe in is a lot of fluoride. That is used a lot in fillings for cavities, but I want to touch more on the resin or composite fillings that most dentists are using. We use composite fillings too. Some things you need to be on the lookout for with composite fillings are the fluoride. Since we’re not a big fluoride user or promoter, we choose filling materials that don’t have fluoride. On the other side there are a lot of dentists that love to have fluoride in everything. There are manufacturers that are placing fluoride in these fillings because they think there’s a benefit. They think fluoride should just be put in everything and if they expose the patient to more fluoride, that can be good. As you know, fluoride is a poison. That’s the reason why on your toothpaste it’s an active ingredient. If you wanted a high fluoride toothpaste you would need a prescription for it, because it is a drug. It’s a medication. We don’t like exposing more toxins to people than necessary, so we’re not going to be placing fillings that have fluoride in them.

There’s also aluminum in these white fillings and barium in these fillings. A lot of these fillings have metals in them, even though they don’t show up as silver or gold. They have metals in them specifically for the dentists to be able to notice that they are fillings in future x-rays. If they put a filling into your mouth, they like to know that it is a filling on the x-ray so they won’t think that it is a cavity. It does have some good reasons why they put metals in there, but it’s not a good enough reason for me. I want to make sure that we use the least toxic materials possible.

The next ingredient in plastic fillings are these BPA type of derivatives. We’re talking about bis GMA and bis DMA and there’s a difference between those two, but for the most part, if you haven’t heard of BPA, it stands for bisphenol A. It’s controversial because it’s a chemical that is found in a lot of plastics. There is a lot of food and drink packaging. It’s found in water bottles; that’s why you see a lot of BPA free bottles out now. Toys, compact discs, foods, cups, there’s a lot of products that are plastic that have BPA in them. What happens is that BPA leaks out of the plastic. It can actually get into your food and the chemical will go into your body. Lab studies have shown that BPA interferes with health hormones operating in the body, such as the production, secretion, function and elimination practices. It’s like estrogen. If it’s like estrogen, your body’s going to react as if it were estrogen. You want to minimize your exposure to BPA. BPA, bis GMA and bis DMA are found in a lot of filling materials. I mean a lot of these composite filling materials. If you’re like me and want to minimize your amount of exposure to them, then you probably don’t want to have BPA in your filling materials. Unfortunately most dentists are unaware of this and they won’t know anything about them. That’s my talk about BPA.

There are other characteristics about composite fillings, pros and cons. Some of them can bond better, some of them have more strength, some of them are easier to place, but that’s for the dentists to deal with. If your dentist wants to be fast and do more or get through the procedure quicker, then he may use a different filling material, just because it has those properties. In our office, we want to use materials that not only last, that have a nice color, that are easier for us to use, that bond well but also are less toxic. That’s very important. Most dentists wont’s choose a different filling material just because you ask for it. They pretty much have one brand of plastic filling material, and they’re going to use what they’ve always used. That’s on particular toxic dental material that most dentists and most people aren’t aware of. That’s the reason we have this show.

You’re listening to Let’s Talk Dentistry. I am Dr. Marvin, a licensed dentist here in California that does biological, holistic, healthy dentistry, and that’s what this show is all about. Today we’re talking to you about toxic dental materials. We’re going to talk a little bit about mercury amalgam fillings.

I just read an article where a dentist says they should not be called mercury fillings, because there’s only a small amount of mercury. I’ve got to tell you, that person’s been brainwashed by the American Dental Association. The amount of mercury in mercury amalgam fillings is over 50%. If it’s over 50%, that means the majority of it is mercury. If the majority of it is mercury, they should be calling them mercury fillings, not silver fillings. Though there are very good things about mercury fillings (such as they’re very functional, they’re strong and the do last), dentists are taught that they have very little mercury, but that’s untrue.

As you know, mercury is a poison. We should minimize our exposure to these poisons. It even says on the box that we should not use them in children under six years old or women that are of child bearing age. There are also other metals in the amalgam, because the mercury amalgam is a mixture. It can have copper in it, and tin, zinc and silver. All of those can cause health issues with you, so again, know your dental materials. Know your plastic materials, know your mercury fillings. There’s also porcelain restorations. Porcelain restorations can be made out of inlays, enlays, there’s just as many porcelain materials as there are filling materials. You just can’t say porcelain, there’s E. Max, there’s lithium disilicate, there’s zirconium, there’s feldspathic, then there are other formulations out there.

There are so many dental materials out there that there’s no way any one person could be up to date with every single material in dentistry. There are crowns out there, metal crowns. If you ask your dentist to make a porcelain crown, they may choose a porcelain that’s baked on to metal. Theses metals act as a substructure for strength, but they also contain nickel. Nickel is cancer-causing, it’s a neurological toxin. There’s also palladium, cobalt, cadmium, barium, it’s not just all precious metals like gold and platinum. It’s a mixture. The more gold in it, the softer it is, but also the more expensive. Since the price of gold has increased so much, a lot of dentists aren’t even placing gold restorations. Just because it’s yellow gold doesn’t mean it’s 100% gold. Just like when you buy jewelry you can get 10k or 15k gold, it’s not pure, 24k gold. It’s an alloy and it’s lower quality. It has less gold content. That’s the same thing with a lot of dentistry and these crowns or bridges that these dentists are placing.

Be very cautious of what dentists put into your mouth, because it’s not only going to cost you to do the dentistry, but it’s also going to cost you in the time, energy, and money to replace the dentistry that other person did. I am all about preserving tooth structure. If you come to me and I say you need to do a certain crown, but you go to another dentist because it’s $50 cheaper, you may have to come back to me. I’ll tell you that the material they used was not compatible to you and it’s affecting your health. I’ll go ahead and take it off, but there’s going to be more damage to your tooth by doing the dentistry a second time. Why didn’t we do it the first time? Because people are trying to save a buck. That’s not what we’re here for. We’re here to provide the best dentistry with the knowledge and expertise to know which material to use.

Be very careful when you go to dentists and you ask for porcelain crowns. They could be using metal crowns, and the porcelain could be bad. There’s aluminum and iron oxides in porcelain. There’s a lot of materials in porcelain. I had a person come up to me at the Earth Fair that told me that the dentist placed an E. Max (that’s a newer porcelain restoration) in his mouth, and he knew immediately that it was not good for his health, but the dentist insisted that the E. Max was perfect. Well, he had a lot of health issues because of that tooth. He had to force the dentist to take that E. Max restoration out of his mouth. When he did, he instantly felt better. How can this be, when supposedly all the manufacturers did all these tests and all these dentists are telling everyone that it’s a good material to use? They’re not checking the biocompatibility with individuals. That’s very important.

Same thing in this last couple of weeks. I had a patient come in with zirconium. A lot of biological dentists and regular dentists are starting to love this zirconia dental material, BruxZir crowns, and all these. We took it out of one patient’s mouth. She had three of them. Two were on root canal treated teeth, but the root canal treated teeth were fine. We took out the crowns, and within three days she had these little boils on the skin of her face that were completely eliminated, because we eliminated the toxins that were affecting here health. It could be affecting her health, and in another person it couldn’t affect their health. That’s some of the stuff we do; we test beforehand.

What about titanium implants? Titanium is used a lot. Since we do ceramic, zirconium implants, we don’t place titanium implants anymore. Titanium has its issues. Just ask Dick Van Dyke and all his issues that went away: headaches, migraines, getting sick more often, everything could come from toxic dental materials.

Do you have a denture? Do you have a flipper? Do you have a partial denture? A lot of these dentures are made out of materials that have cadmium in it. Cadmium is a neuro-toxin. The teeth themselves, the wires that they use can have stainless steel or nickel chromium. Those are bad for you. Polymethyl methacrylate is a material used in bike parts and for the pink parts of partials and dentures. If your dentist is using those and you have redness on your gums, you could be allergic to it. Polymethyl methacrylate, I want you to go and find a tube of super glue and look at the ingredients. That’s what it is. When you crack open super glue and you smell it, it has a strong smell; you have to take a step back. Those materials are constantly giving off fumes. If they’re constantly giving off fumes and you keep them in your mouth for a long time, what’s the long term effects of that?

Orthodontics, sleep apnea appliances, there are dental materials everywhere. Dentists are not checking to see if they’re good for you. They’re just using them because that’s what they’ve done in the past, and that’s what their colleagues use. It’s very important that you make the right decision.

So let’s get to the bottom line. If you want to live a long, healthy lifestyle, you need to make a decision to minimize the amount of toxins in your life. We’re talking about the air you breathe, the food you eat, whatever you put in your mouth, drinks, whatever you smoke, whatever you put on your body, your lotion, your antiperspirant, your make up, your clothes that you wear, the sheets that you sleep on, your bed, the mold in your house, the air in your house, the air outside of your house, the air inside your car, the food, when you go outside, when you go cycling on your bicycle. Is the air you breathe healthy? You need to make decisions on whether those are good for you. Think of it as accumulating over time. If you’re accumulating these toxins over time and you want to minimize your health risks, then you need to make choices to minimize your toxins. That’s what we’re talking about in dentistry. We want to minimize your exposure to toxins. Just because you have a little bit of BPA in a filling doesn’t mean that you don’t get to add all that BPA from the plastic container or the plastic tupperware you cooked your food with in the microwave. It doesn’t take into account the liquid that your drinking with BPA from the water bottle. It’s all accumulating over time. What you need to do is prevent toxins from your life. It’s much better to know what’s going on before hand so you can make a decision whether you want to increase your burden of toxicity. Personally I feel that toxicity causes chronic illnesses. It causes a lot of inflammation. Your body is reacting to all these toxins constantly over time, then pretty much your immune system gives up. Then you start becoming more prone to illness; you get other chronic diseases like heart troubles, strokes, diabetes, auto-immune problems, you name it. Most chronic illnesses are an inflammatory disease, and a lot of people are going after the wrong topic. The topic should be “toxins.”

If you start developing symptoms, figure out the cause, but a lot of times it’s difficult to do that or it’s too late to do that. If you are going to be proactive with your health you want to try to minimize your exposure to toxins, not only in dentistry but all over, but if it is in dentistry I want you to go to a dentist that understands that dental materials can be and are toxic. Those type of dentists will go out and search to find out what material is best, because there’s not one best material but the better materials, and that dentist is going to test each patient before the dentistry is performed. That’s one thing we pride ourselves in at The Center for Natural Dentistry. We test our materials before we use them. We don’t want to test afterward. We don’t want to just not test and hope that the material doesn’t react to you. We test before hand, and that’s very important. We don’t charge an additional fee to test these materials. We also use biocompatible materials like BPA free, fluoride free, and zirconium implants, and feldspathic porcelain. We test these materials way ahead of time, so we have a good idea of how to prepare the teeth and how long it’s going to take. It’s just an extra or additional level of care that I believe that most dentists are not doing or they don’t care to do.

Finally there is always some level of toxicity in all dental materials. Yes I am a purist, but the best dental material to repair your teeth with a lot of times is your own enamel. Unfortunately we’re not growing teeth and we don’t have the enamel in a dispenser that we can put on your teeth. Enamel is very brittle, we can’t grow it, and we can’t bond it to your teeth. Don’t even think about that idea of putting on enamel just yet. When it comes to dental materials we have to use the safest material even though it’s not the ideal or the original material.

One other idea that I don’t want you to forget is that just because it worked for me doesn’t necessarily mean it doesn’t work for you. A lot of dentist when they’re talking about amalgam fillings will say, “Look I have an amalgam filling in my mouth and I’m OK.” Well that’s not a very good reason, because they may not be OK on the inside. They just don’t feel any symptoms. The second thing is it may be OK for them, but for someone else it could be toxic, because they’re not testing individuals. That’s another problem. When you ask a dentist if they would do it all over again (place a mercury filling in their mouth) they would say they would put something different. They would put something white that obviously doesn’t have mercury in it. You do have the choice, if it’s for your child, for your spouse, or for yourself, I want you to choose health. You don’t know what material or what toxin could put you over the edge and eventually cause a cancer or a chronic illness that everyone hopes that they never get. God forbid that we get these, but a lot of people, even the young people are getting ill. We are supposedly the smartest, healthiest country out there, and that really irks me. This is where capitalism and health care just don’t match up. When you go to a doctor they’re looking at your health interests, but they’re also looking out for their pocket book. It’s a very difficult decision for dentists to do or doctors to do. Just remember where they’re coming from, and of course prevention is key.

Let’s stop talking about how fluoride can prevent cavities, when eating healthy can prevent cavities. That’s very important. When you’re over weight we don’t talk about the surgery or the tummy tuck. Let’s talk about the diet and the exercise that should be the focus. Let’s get down to the cause.

I am Dr. Marvin. I’m going to offer a special today for today’s listeners only. I want to offer those that listened today, the first three callers to 760-536-1199, I’d like to see you as a new patient. I’d like to do an exam. If you pay for an exam I will give you your x-rays and a free cleaning. X-rays and a free cleaning, that offer is $199. You pay $199 and you get the x-rays, which at some places are like $350. Ours is going to be free. And a cleaning. That’s $100, that will be free. So take advantage of the special today.

Thanks for joining me today. I always love talking to you and I hope you love listening. Keep smiling and have a great week.

  2. I really wish more dentist understood this.
    I refuse fillings.
    Every tooth I have had with a filling ends up falling apart.

    I floss and brush good. I need a fluoride free toothpaste because arm and hammer started using it.
    I also do oil pulling with coconut oil. I know I have other cavities but they seem fine because I take care of my teeth(floss floss floss..this is why I have cavities is because I never flossed!!).
    My current issue is my son. He is 14 months. His top 4 teeth are decaying and his dentist is saying bottle rot. He breastfeeds. I have read enough to simply is not from breastfeeding. I know kids who breastfeed like him..even at night. Their teeth are fine..even one who got cows milk at 1yrs old.

    It’s about teeth health.
    I had bad morning sickness in the beginning of my pregnancy and think he didn’t get what he needed because of that.
    I also read a study on breastfed babies and teeth. There was no proof what so ever of breastfeeding causing decay. They even found something in breastmilk that was suppose to help protect teeth.
    Teeth simply do not decay like this.
    He was lacking something and I believe that’s what’s causing it. His enamel was weak.
    Of course his dentist doesn’t care to look further into his diet.

    I have been giving him cod liver oil and a vitamin to see if it’ll help.
    I also try to brush his teeth twice a day.
    I am hesitant to cap his teeth. It’s either that or having them pulled.
    I have no clue if I want that metal in his mouth. I’m trying to find out what is used. The teeth do hurt him so doing nothing is not an option.

    I wish I could find a dentist that actually understands tooth decay and isn’t ignorant.

    Teeth health is about diet!!!
    More dentist need to learn this!!

    But I guess there is no money in healthy people!

  3. It’s so awful that we put trust in these people! I empathise with anyone struggling. It’s so upsetting on a daily basis and they’re so expensive too, so it’s not like things can be changed at a moments notice. It’s so ridiculously obvious that mercury is poison. I commented to a dentist when I was 17 that I would have thought mercury amalgam would be unhealthy, because we learned it was a toxic poison at school. He said it was perfectly safe. Just totally disregarded. Just goes to show that we should trust our instincts. Also, dentists are trained by older dentists, so isn’t any wonder amalgams have been used for 150 years. Surely the first thing any practitioner would consider is “Is this safe?” It’s overwhelmingly negligent

  4. Laurie Wilson Says: March 13, 2019 at 4:19 pm

    I am having sensitivity on my tongue, it feels tingly and numb. I had all new crowns on top and bottom made of Emax porcelain. Can this be the cause?

  5. William Finn Says: February 3, 2019 at 5:45 pm

    I had work done by comfort dental a root canal I know destroyed parts of my brain from whatever is in them. They used plastics. I can no longer sleep. These teeth I want out of my head so badly, it is the work of the devil.

    • I watched Root Cause on Netflix, essentially, root canal treatment is the only time a dead part of a body is left in the body, so highly toxic. Mine caused severe health problems too

  6. I just went to the dentist and there is decay under an EMax crown that’s only 5 years old and I have to have it replaced. I was told by my hygienist that it was soft down there for about a year.
    I don’t know why this would happen. Was the crown placed improperly? If that were the case my hygienist (I use a different office for this) would have said something after I had it placed and she said he did a good job.
    It’s on a large molar, should a diffenet material have been used? He has that convenient Cerec Machine .Or is it just that my gums receded and decay got in underneath and it doesn’t matter what material was used?
    I get a cleaning 4 times a year, use a Sonicare, floss twice a day and use soft picks.
    I am so bummed out right now

      I live in the UK and just wish to share some thoughts about the materials that dent’s use.
      I got rid of all my Amalgam fillings 11 years ago and they were replaced with white fillings-these I believed were much better!! Wrong- they are full of noxious chemicals, Aluminium which settles in the brain and contributes to memory loss. It has some mercury also in it which does the same and is highly dangerous to have in your body. This white composite has other toxins in it as well including the dangerous PBA Composite which is an endocrine Disrupter?!!
      So I thought fine I’ll have PBA free Composite fillings from now on! I’ve found all of the above are still present in these fillings.

      The X-Rays that dentists seem to give you willy nilly these days destroy Calcium in your teeth and body. I have just come from my dentist today and had three X-Rays. I asked if these were necessary and the reply was they were as he wanted to see what was going on with my teeth!!!

      I don’t know about Root Canals but I’ve been told by a wholistic expert that they are very dicy and contain a lot of toxins which can leach into your body. I have been advised by this friend to keep well away from dentists and she has given me a list of natural ways to deal with my teeth.

      I am now very troubled because she said there are no dentists in the UK who actually can give you any fillings that are harmless and that they know nothing about their products or what harm they can do. And we are at their mercy.

      I believe that my gums were damaged by this cleaning that dentist carry and then food gets down inside the gums and infection sets in. My lower gums now are inflamed. I am trying some new ideas I only hope the dental profession gets its act together and wakes up to the harm its doing!

      Jay Melville.

  7. Clairetta Anderson Says: August 7, 2018 at 9:34 pm

    I just got new dentures. I am convinced they are toxic as I feel like I have chronic bronchitis when I don’t. Also, there is a bitter taste in my mouth and my throat. They are the darkest pink I’ve ever seen in my dentures. This is my 5th. upper and third lower.

    I read there is a product that will remove the toxicity in dentures. Is this possible?

    Should I just get a different set? I cannot afford implants. Thanks.

  8. Carol Robertson Says: June 23, 2018 at 7:31 pm

    I have a mouth full of new zirconium crowns. The premolars and molars are a real problem. My food sticks to the chewing surface where there are tiny “bumps” that appear to contribute to trapping food in the surface. I end up trying to chew my food with the food that is stuck to the surface rather than the actual surface of the crown itself. It is affecting the taste and flavors of my food and sometimes makes me feel a little nauseated. When this happens I lose my appetite and just quit eating. Have you ever heard of this??? I’ve had plenty of crowns over the past 50 years and have never had this experience before. I’m confused and angry. I’m thinking that these simply were not properly made….

  9. Because of tjm, i have to have upper and lower full dentures.that i will have to wear full time… I want a metal inside plate. Adviised, chrome cobalt???? Is this non toxic. Or which, metals would you recomend as inert. I am mercury sensitive, and food, and chemical sensitivitys…. so need know.
    If poss could you email me, thanks.
    Incase i looze yr site address. Thanks lin

  10. Christine Margo Says: January 22, 2018 at 7:46 pm

    Can you tell me if the material used is JRVT alloy, is toxic? It’s mostly gold with silver, copper and palladium. I have cancer and don’t want to add to the toxic levels in my body. Dentist was not totally sure.
    Which is better….gold and platinum, or the other above mentioned one? He said the gold /platinum was better, but softer and wouldn’t hold up as great. I’m 65, not that concerned.
    Same price, whichever one I chose.

  11. So basically there is no solution for anyone? Wow. I’d love to know how you do the testing.

    Shame he didn’t tell the truth – that Feldspathic Porcelain actually has Aluminium in it anyway.

  12. What dental cement for a crown is not flouride releasing!

  13. I am supposed to have a few fillings this month and after reading about the toxicity of dental fillings am horrified and frightened. I know my cavities need care but I am too scared to let them be filled now. Please if you can answer my question as soon as possible I would deeply appreciate it.

  14. Roben Audi Says: April 16, 2017 at 4:52 am

    Then what kind of crown can you put in your mouth
