Porcelain fillings are a relatively new procedure, and information about how long they will last and the factors that affect their lifespan is still in flux. Preliminary evidence suggests that porcelain fillings can last for 15 to 30 years. However, many studies involving the durability of porcelain fillings were conducted on fillings placed prior to advancements in both material and bonding procedures.
The typical lifespan of a metal amalgam filling is around 15 years. Metal fillings are not permanently bonded and can be impacted by heat changes in your mouth, which can cause them to loosen or fall out. This is not the case with porcelain fillings.
Porcelain fillings do not expand contract with heat changes, remaining in place for a much longer time. In addition, porcelain has a similar wear rate to natural tooth enamel. This means that porcelain fillings do not wear down in the same manner as metal fillings, and provide a longer lasting solution. In fact, according to the American Dental Association, porcelain fillings are the most wear-resistant type of filling available today.
There is no way to determine how long your porcelain fillings will last. But with a proper oral hygiene routine and regular cleanings and examinations at our office, your porcelain fillings have the potential to last for a lifetime.
