Dentists still learn how to place metal fillings in dental school, but you don’t see them used much these days. If you really wanted one, it could still be done.
But there are solid reasons why metal fillings are going out of date. Most of today’s dentists open up their practices right from the start offering only white composite dental fillings, so you’re bound to have a hard time finding metal ones. Here’s why:
White Fillings – Kind To Teeth
Metal fillings don’t create a very snug seal with the tooth. Thus, they require more of the tooth to be carved out so they can be anchored in place. White ones form a chemical bond with tooth enamel so they can afford to be more minimal in design.
While amalgam restorations are strong and long-lasting, they can sometimes be too strong for the tooth. The metal expands and contracts with temperature change at a rate faster than the tooth itself does, creating tiny cracks that allow bacteria to leak in. Conversely, composite fillings “give” similar to natural teeth.
For Future Reference
White composite fillings allow for a little more visibility on dental x-rays. A large metal restoration can block the view and is better at hiding sneaky cavities. If you develop new decay, you’ll be glad to catch it early on.
Err On The Safe Side And Go Mercury-Free
Tooth-colored dental fillings don’t contain any mercury. Granted, the traces in metal fillings are too small to worry about, but not having to deal with the substance anymore is healthier for patient and dentist, alike.
