How durable are the fillings?

The durability of restorative fillings varies depending on the material used, the tooth’s location, and individual factors. Amalgam fillings can last between 10 and 20 years, with some studies indicating an average lifespan in this range. Composite resin fillings, on the other hand, last an average of 7.8 years, but their lifespan has increased with advancements in materials and techniques. The size of the filling, the location of the tooth, oral hygiene, and habits such as teeth grinding can all affect the filling’s lifespan. Regular dental checkups are important to ensure the longevity of fillings.
