Should I Remove My Amalgam Fillings?

My dentist is suggesting I replace my amalgam fillings. He told me there is nothing wrong with them, but he thinks it is best to replace them with composite fillings. I am wondering if I really need to do this. I don’t have money right now, but he hinted they will go eventually and it’s better to change them when everything is okay. What is your opinion of this?


Dear Jenn,

Before and after mercury free fillings

No, you don’t have to change out these dental fillings. While I am grateful that your dentist was honest enough to tell you that there was nothing wrong with your fillings, I am suspicious of the low-key pressure he is putting on you to replace these fillings.

Composite fillings are better than amalgam fillings, but if they are not cracking and are not leaking it is not necessary. Your dentist could just keep an eye on them and then let you know when they truly needed to be replaced. It is not fair for him to pressure you like that.

If it gets to the point that you do need them replaced then I want you to make sure he knows how to do a sanitary amalgam removal. These silver amalgam fillings have mercury as their main ingredient. There are special procedures and equipment that need to be in place in order to keep you from inhaling any mercury vapors or swallowing any pieces of the filling.

If he doesn’t know the procedure for a sanitary amalgam removal, then look for a mercury-free dentist.

White Fillings in Children

I have a question about white fillings. My son needs his first filling. I am really uncomfortable with the silver fillings because of the mercury in them. I asked my dentist about getting him a white filling but he said they don’t work well in children. Why is that? Will the silver ones be dangerous for him?


Dear Mallory,

Let’s start with your last question first. Are the silver fillings dangerous? The American Dental Association still says that silver amalgam fillings are safe. Understandably, though, many patients and parents are uncomfortable with the high mercury content.

While composite (white) fillings are a tad trickier with children, that doesn’t mean they are not able to have white fillings. The struggle is because the composite material has to stay completely dry while it is being placed. That can be tricky for wiggly little ones.

If having a composite filling is important to you, I have found that using some nitrous oxide allows the children to completely relax if their nerves are making them figity. Most of the time they end up sleeping through the procedure.

That being said, I wouldn’t push your current dentist into this. The technique for placing composite fillings is completely different from placing amalgam fillings. I have often found that dentists who try to steer you to a different procedure are actually doing that to keep from admitting they can’t do the one you want. If you pressure him into the other procedure, he will likely not do it correctly.

I suggest that you look for a dentist who advertises as a mercury-free dentist and then see if they are also a pediatric dentist. They don’t have to be a pediatric specialist. Instead, they can be a general dentist who enjoys treating children. They are qualified and do a pediatric rotation so your children will be in good hands.

Do Amalgam Fillings Stain Teeth?

I have two amalgam fillings that cover about 70% of my tooth. I want to remove them and replace them with composite fillings. He said the amalgam stains teeth and they won’t look nearly as good. Is that true? Should I leave the amalgam fillings on?


Dear Meredith,

While there is some staining of teeth with amalgam fillings, they will always look better with composite fillings. Always. In addition, while amalgam fillings simply rest on the tooth, composite fillings are bonded directly to the tooth which strengthens the tooth and puts it at less of a risk for fracture.

I suspect your dentist said that to disuade you from switching. This is likely because he is uncomfortable placing composite fillings. They are placed with a completely different technique than he or she is used to placing the old amalgam fillings.

I don’t recommend you push him into doing it though. There are horror stories of patients who ended up needing a root canal treatment after a dentist placed them incorrectly. Even if it isn’t that bad, you could end up with other issues.

If you want this done right, I suggest going to a dentist who is familiar with placing them. You can do an internet search using the term mercury-free dentist. These dentists only place composite fillings and have the technique down pat.

I have one other concern I’d like to address. You mentioned your current fillings cover 70% of your tooth. In that case, your dentist really should have done a dental crown to adequately protect your tooth. This additional information puts me more in doubt of his abilities. You may want to start looking for another dentist, who can better meet your needs.
