I finally got courage to remove all my root canalled teeth, 5 upper teeth and 2 lower teeth, needless to say, I need a denture in the rest of my life. Now I have a confused question. My dentist find a cavity in one of my rest upper molar, at first we both agree to fill it with gold, but then I realize that my future denture is going to clasped with that molar, and I heard two different metal can produce those electric shock in your mouth,which sounds really scaring. I want to ask Bryanna, do you have any patient ever has such experience, I mean metal denture wrapped around gold fillings and is fine with it? Thank you very much!

In addition, I'm planning to have a titanium or vitallium based denture, because the valplast one I'm wearing now does feel good,it becomes rough very quickly. Do you think titanium denture is biocompatible? Thanks!

Hi vichen,

Good to hear that you've removed the unhealthy teeth and you're moving forward with the replacement of those teeth. I know it's a lot to go through but you are doing great!!

Regarding the gold filling and future metals in your mouth. There are some metals that should not be in contact with each other because one or more of them will have a potential to corrode the other. In the mouth certain dissimilar metals will have what is called a Galvanic response and/or lead to Galvanic corrosion. Galvanic is an electrical current caused by a chemical action. In the mouth the saliva is the chemical that causes the dissimilar metals to give off an electrical current. In addition to that, corrosion of certain metals will occur with or without the help of the saliva.

Vitallium and titanium alloys are both used for partial dentures but they are very different from each other. Both are considered bio compatible materials meaning they are non reactive for many people. However, what one person reacts to another person may not. So they are only bio compatible to people who are not reactive to them. You can be tested for your personal bio compatibilities prior to having the partial made. This can be done with a blood test or kinesiology (muscle testing).

The Galvanic issue is complicated and if you are concerned about it, you need to discuss it with your dentist and have him discuss it with his dental lab. He and the lab can come up with a solution as to what combination of metals would have the least (if any) galvanic response.

Hope this info helps......

Thank you so much for your replying. My next appointment with my dentist to fill the cavity is on next Tuesday. Unfortunately I still haven't decided which material I would use. It just like everything is toxic on some level. Dear Bryanna, if you were me, would you choose composite over gold fillings, or not.
I'm really confused, don't know which one is more healthy

The reason i dislike composite is it not only release BPA, but also release
Formaldehyde over time, is it true? If it is, it sounds really disgusting

Vichen---There are many different brands of composite. Many are BPA free. Your dentist should be able to find one that will work for you. I am not aware that they have formaldehyde. I would personally want composite over the other filling alternatives, but of course that is up to you. I just wanted to let you know that not all composite has BPA.

Thanks,Nukuspot, hearing composites do not release formaldehyde is very relieved. If you do a little search on line about composites and formaldehyde, there are tons of article claimed they do contain this component,which really get me confused and desperate.

My dentist wants to use Synergy D6 for me to fill the cavity, i don't know if it has BPA, did not see anything about it on line.

vichen,

Unfortunately, there is no non toxic material for dental fillings. Every material used is a mixture of chemicals or metals. Even gold fillings and gold crowns are mixed with other metals because gold is too soft to work with so it needs harder metals to form it into something.

Indirect composites, these are fillings made in a dental lab similar to the way crowns are made. They require 2 visits and are more costly than routine composite fillings. Indirect composites tend to be less toxic compared to direct composites which are those fillings that are made from a prefabricated material and take one visit to complete.

As I've mentioned earlier, each individual has their own unique biochemical reaction. So what one person reacts negatively to, another person may not react at all. So what I would favor for myself is something that I am personally bio compatible to.

Well actually, I have almost half a dozen composites in my mouth, and I don't think I'm allergic to this material, I used to have silver fillings,which I was not react to either. It just thinking of composites release those formaldehyde and BPA things makes me sick. And as you mentioned, even gold fillings is not pure gold, it contains palladium which is not good for health, so now I'm really don't know what to go with. It's a small cavity on the side of one upper molar.
