Cavities are one of the most common dental problems, but the good news is they’re very treatable.
When you have a cavity, your dentist removes the decayed portion of the tooth and fills the space to protect the healthy tooth structure. This restores the tooth so it can function normally again.
There are several materials that can be used for dental fillings today. Depending on the material and how well you care for your teeth, fillings typically last between 7–15 years. In some cases, gold fillings can last even longer.
Common types of dental fillings include composite resin, silver amalgam, ceramic, and gold.
Good oral hygiene and regular dental visits can help keep your fillings — and your teeth — in great shape.
