Have you been told that it is time to replace your old silver fillings but they seem fine to you? Well it is broke, in a way.
Here’s the problem. Amalgam (silver) fillings expand and contract over time. This causes stress fractures in the tooth and over time these fractures can become deep enough to cause large pieces of the tooth to break away. Once a tooth breaks you have no control over the extent of the damage. Can you say root canal and a crown?
Also, decay can be masked on a radiograph when next to an amalgam filling. The metal blocks the x-ray from passing through and decay can be undetectable until quite large.
Chances are you’ve had these suckers for quite sometime and they are now time bombs waiting to go off. Don’t get caught with a tooth ache, broken tooth, or a filling that falls out leaving a huge hole.
Just bite the bullet and get them replaced while the task is still a small one.
