A common misconception is that once you get a cavity filled, it lasts a lifetime. Unfortunately, that’s just not the case. The lifespan of dental fillings depends on what type of material is used to fill the cavity.

Composite Resin Fillings

Because we’re able to match the resin filling material to the color of your natural teeth, composite resin fillings are a great choice to restore your teeth and enhance your natural smile.

The seal created by a resin filling is very strong because it bonds directly to the tooth. The material is also durable and provides good protection.

Composite resin fillings are aesthetically pleasing because the color closely matches the existing teeth. Composites are particularly well-suited to use for front teeth or visible parts of the teeth. They’re also quite versatile and can be used to repair chipped or worn-out teeth. Only a small bit of the healthy tooth needs to be removed, unlike with silver amalgam fillings.

While composite fillings are not as strong as amalgam ones, they can last for many years. Most composite fillings last around 5 years, with many instances in which they’ve lasted 10 years or more. Several factors can determine the lifespan of your composite filling, including diet, hygiene habits and whether you have bruxism.

Amalgam (Silver) Fillings

Amalgram fillings (also known as silver fillings) on average last 10-15 years. By nature, a dental amalgam filling is self-sealing. Changes take place with the metal itself over time that tend to fill in any micro spaces that exist between it and its tooth. Amalgam fillings are very strong and durable and can withstand heavy biting forces. They also seal out bacteria and are a good choice for restoring tooth function.
