Smoking And Drinking Can Cause Fillings To Fail

Yes, this is true. The Pittsburgh Dental School did some research and found that people who drink and/or smoke have a greater number of filling that fail.

It turns out that the chemicals in alcohol and a cigarette can actually degrade the bond used by dentists to put a filling in. It will actually cause the bond between the filling and the tooth's surface to fail and cause the filling to fall out.

The interesting thing is that a filling failure could also be a genetic condition in most people. A difference in the gene for matrix metalloproteinase (MMP2), an enzyme found in teeth, was linked to increased filling failure. Those that have that difference could be higher risk for filling failure, and drinking and smoking can amplify it in them quicker that a person without it who smokes and drinks.
