Oral decay is caused by plaque and infection, and dental fillings help restore the affected tooth. It’s common for pediatric dentists to perform the procedure on children to protect emerging and permanent teeth from further damage. If your little one needs a filling, here's more information about its life span and how to maintain it.

A Parent's Guide to Dental Fillings

How long do they last?

Fillings are designed to endure 5 to 30 years, and the duration will typically depend on the type of filling material used. Silver amalgam versions can remain intact for 10 to 15 years, while composite and porcelain fillings may need replacing after five to even years. Gold fillings can last 15 to 30 years.

Which factors affect its life span?

Besides the filling's material, its size affects its life span. Small fillings typically mean the majority of the tooth is still healthy, so the filling may last longer. Bigger fillings indicate there’s not much of the remaining tooth left, and developing cracks may affect its longevity and require a replacement sooner.

When is a replacement needed?

If a filling cracks or falls out, a replacement will be needed to protect the tooth from infection. Children who are experiencing sensitivity to cold or hot foods for more than three weeks may have a leaky filling.

Except for gold, other versions can leak after prolonged contact with hot and cold food temperatures. In any of these scenarios, a pediatric dentist will determine if the filling needs to be repaired or replaced.

How can I help my child?

One of the best ways for children to take care of their fillings is through proper and daily brushing and flossing. Doing so helps remove trapped food particles that can cause gum disease and weaken the surrounding tooth and filling.

You should also monitor your little one's consumption of hard foods, such as candy, nuts, and ice, which can cause a filling to break or loosen. Regular appointments with their pediatric dentist will also help ensure the filling remains intact.
