How Long Do Fillings Last? What Affects Their Lifespan?

Dental fillings are a common and important part of maintaining oral health, but like most things, they don’t last forever. At Granbury Park Dental, Dr. Paul Froude and our team often hear this question from patients: how long should my filling last? The answer depends on a few key factors—including the material used, your oral habits, and even where the filling is located in your mouth.

Average Lifespan of Dental Fillings

On average, most fillings last between 5 to 15 years. Some materials naturally wear down faster than others, while others can hold up for decades with the right care. Here’s a general idea of lifespan by type:

• Composite (tooth-colored) fillings: 5–10 years
• Amalgam (silver) fillings: 10–15 years
• Gold fillings: 15–30 years
• Ceramic fillings: 15 years or more with excellent care

These estimates aren’t set in stone—some people may need a replacement sooner, while others can go much longer without issues. It all depends on how the filling is maintained and how much stress it’s under daily.

What Can Shorten the Life of a Filling?

Several things can cause a filling to wear out or break down earlier than expected:

• Biting or chewing on hard objects – like ice, pens, or hard candies
• Teeth grinding or jaw clenching – which places added pressure on the filling, often at night
• Poor oral hygiene – can lead to decay around or under the filling
• Large fillings – cover more surface area and tend to wear out faster
• Acidic or sugary diets – increase the risk of decay near the filling
• Frequent snacking – can expose teeth to more bacterial activity

Even with good care, fillings will eventually wear down. Over time, the edges may begin to pull away from the surrounding tooth structure, creating small gaps where bacteria can slip in and lead to further decay.

Signs It Might Be Time for a Replacement

Some signs that your filling may need to be replaced aren’t always obvious. You might feel subtle changes before anything becomes visibly noticeable. Be on the lookout for:

• Sensitivity when eating or drinking hot, cold, or sweet items
• A rough or jagged feeling when you run your tongue over the tooth
• Pain or discomfort when chewing
• Visible cracks or discoloration around the filling
• Food getting stuck in the same spot

Addressing these symptoms early can help avoid bigger issues, like needing a dental crown or even a root canal if decay spreads to the inner tooth.

Helping Your Fillings Last Longer

While fillings don’t last forever, there’s a lot you can do to help them stay in great shape:

• Brush with fluoride toothpaste at least twice a day
• Floss daily to remove plaque from hard-to-reach areas
• Schedule regular dental checkups and professional cleanings
• Avoid chewing on pens, ice, or your fingernails
• Use a custom nightguard if you grind or clench your teeth
• Cut back on sugary snacks and acidic drinks that can wear down enamel

Routine visits allow us to monitor your fillings closely and spot small issues before they become big problems.
