Question from our Readers: When to Replace Fillings

Reader Question: I've had the same fillings for years. How do I know when it's time to replace them?

Regardless of how long you’ve had your fillings, there are a few telltale signs that you should replace them:

• Sensitivity to cold, hot, or sweet foods
• A sharp or lingering pain when you eat or drink
• Discoloration or darkening
• Cracks, chips, or rough edges around the filling
• Pain or discomfort around the filled tooth

These are all signs that your fillings may be worn or damaged. If you notice any of these signs, I strongly suggest contacting a dentist. 

They can evaluate the condition of your fillings and replace them if necessary. They can also look for any underlying conditions affecting your fillings or teeth.

How long do fillings actually last?

Typically, fillings last 5 to 15 years. However, this can vary depending on the filling’s material type, size, location, and how well you’ve cared for your teeth. 

For example, silver (amalgam) fillings are the most durable and can last up to 15 years or longer. Composite fillings, on the other hand, may need a replacement much sooner, especially if they’re large or on a tooth that gets a lot of wear and tear.

How much would it cost to replace a filling?

On average, replacing dental fillings can cost between $50 and $500. However, this depends on the type of material used for the filling.

Fortunately, dental fillings are generally covered by most dental insurance plans. If you don’t have insurance, many dentists offer flexible payment options to make the procedure more affordable.
