Why Do I Need A Filling?

Decay is not the only reason you may need a filling. Cracked or broken teeth or teeth that are worn from unusual use— such as nail-biting, tooth grinding or using your teeth to open things—may also need fillings.

Why Replace a Filling?

Fillings don’t last forever. When you chew, your teeth and any fillings in them are subjected to tremendous pressures. Even if no other problems develop, some fillings will wear out over time and will need to be replaced. A filling will need to be replaced earlier if it falls out, leaks or cracks. A filling that is cracked or leaking can allow food debris and bacteria in your mouth to seep down under the filling. Since you can’t clean there, the bacteria feed on the food debris and form the acid that causes tooth decay. Decay under a filling can become extensive before you notice it or it causes you pain. This can be prevented by having your fillings checked regularly and getting them replaced when problems are found. If the restoration is large or the recurrent decay is extensive, there may not be enough tooth structure remaining to support a regular filling. In these cases, your dentist may need to replace the filling with an onlay or crown.Are you worried your old fillings may need to be replaced?
