The mouth is a harsh place.
Pressure from chewing, grinding or clenching can cause dental fillings (restorations) to wear, chip or crack. Acids dissolve tooth minerals and decay undermines tooth structure and causes cavities which, if left untreated, can progress to the nerve and cause toothache.
All restorations in the mouth have a finite life span. You may not know if your old fillings are wearing down, but your dentist can identify problems during regular check-ups.
The various filling options enable the teeth to be restored to a better shape and function with modern materials performing more effectivelly and more visually appealing to the eye..
Should the restoration be extensive, there may not be enough tooth structure remaining to support a replacement filling. In these cases, your dentist may need to place a crown.
A direct restoration involves placing a filling into a prepared tooth cavity, which can generally be done in one visit to the dentist. There are a variety of filling options available, which will be recommended based on the type and location of the filling.
