Tooth decay occurs when acids produced by bacteria erode and damage the surface of the tooth. This can cause cavitated openings in the tooth which can get larger and lead to infection if it goes untreated. The decay needs to be removed and replaced by a filling or crown. Although composite resins are cosmetically pleasing and easily placed, their durability is not as strong as other types of restorations. These resins typically last from 4-7 years before they begin to chip and wear away. When this happens, the restoration will need to be replaced.
As we age, our teeth begin to change and are prone to decay. There are many possible reasons for this change in your smile. These reasons can include bruxism (teeth grinding), general decay, cracked fillings, root canals, and many others. If your tooth is beyond repair with a filling material, we may recommend that the best viable option to save the tooth is a full coverage crown. The reasons for this type of restoration in a badly damaged tooth are durability, cosmetic appearance, and overall support of the chewing function. If a tooth or many teeth are lost completely, talk to your dentist about other replacement options including dental implants or removable prostheses.
