Mercury, or amalgam, fillings can be problematic because when the mercury inside the fillings expand and contract, it can lead to a breakdown of the filling and tooth. That allows for decay, bacteria and infections to seep down into the tooth often leading to recurrent decay, according to Dr. Mitch Conditt, a dentist in Fort Worth, Texas. There are also often fractures on the teeth with amalgam fillings, which can break off and cause painful situations leading to root canals or extractions.
If you have amalgam fillings, Dr. Conditt recommends having your dentist look at them first, as they may be in good shape. If there is something wrong with them, they should be replaced as soon as possible with a tooth-colored filling or a crown. The important thing to remember is that once something is happening, it's important to get it restored, he says.
There can be lots of things going on in the mouth and body when there is tooth decay with no pain being felt, Dr. Conditt explains and if there is something going on, getting that tooth restored as soon as possible is important.
