Dental fillings are one of the most common treatments dentists provide—and also one of the most important! They’re strong, reliable, and designed to stop decay from spreading, so your smile stays healthy. But like all things, fillings won’t last forever. But how long can you expect to keep them? Keep reading to learn how long a dental filling lasts and when you might need a new one.
How Long Do Dental Fillings Last?
Most dental fillings last 10 to 15 years, though some last much longer! The exact lifespan depends on multiple factors, including the material used, the size of the cavity, and how well you care for your teeth.
With the advancement of dental technology and materials, modern composite (tooth-colored) fillings typically last around 7 to 12 years. However, no matter the material, a filling’s job is the same: to protect your tooth and keep it strong.
How Do You Know If Your Fillings Need to be Replaced?
Most dental fillings don’t fail overnight. They can talk to you in a way, giving you subtle clues as they age. Call your dentist if you notice:
- Sensitivity to hot, cold, or sweet foods
- A rough or sharp edge on the tooth
- A visible crack or gap
- Food catching in the area
- Pain when chewing
Even a small opening around a filling can let bacteria in, so seeing your dentist sooner rather than later can prevent dental emergencies and expensive alternatives.
How To Make Dental Fillings Last Longer
Good habits make a big difference. If you want to maximize the lifespan of your fillings, brush twice a day, floss daily, and visit your dentist for regular checkups. This keeps your teeth in great shape and allows your dentist to stop problems before they worsen.
In some cases, they may also recommend wearing a nightguard, which can help if you grind your teeth. Finally, avoid chewing hard objects like pens, ice, or hard candy. These can be unassuming dangers for your pearly whites.
Dental fillings are a fantastic way to keep your teeth healthy. With good care and regular dental visits, they can last for many, many years. If you’re unsure whether a filling needs attention, call your dental team! They can check your mouth during your next visit and help make sure your smile stays strong.
