How to Get the Most Longevity Out of Your Dental Filling

September 8, 2026

When it comes to dental fillings, chances are, nearly everyone in your life has one. Cavities are one of the most common oral health problems across the globe, which makes fillings incredibly popular, too. They’re designed to prevent the spread of decay and further damage to your tooth, like an infection. However, while they’re designed to be durable, they will eventually need to be replaced. Read on to learn how to extend the lifespan of your dental filling and how you can tell it’s time to get it replaced.

How Long Do Dental Fillings Last?

There are several different types of dental fillings, all with differing lifespans. Metal amalgam and gold fillings typically aren’t the go-to choice of dentists anymore due to the risk of allergic reactions, their esthetics, and the need to alter more of a natural tooth in order to place them. However, one of their big benefits is the fact that they can last for over a decade in the right conditions.

On the other hand, tooth-colored fillings (also known as composite fillings) blend in with your natural tooth and are more visually appealing. They typically last for between five and seven years with good oral hygiene practices.

How Can You Tell It’s Time to Replace a Filling?

Over time, your filling will lose its durability and can fall out or wear-down, leaving your tooth at-risk of secondary decay. It’s important to be able to tell when it’s time to have it replaced. Here are some common signs to help you tell:

  • There are visible cracks, chips, or missing pieces from the filling
  • Your filling is visibly stained or discolored, especially at the margins where the composite meets your tooth
  • You experience pain or sensitivity around the treated tooth

At each of your bi-annual checkups with your dentist, they will examine your filling to see if it needs to be replaced, being proactive about your dental health!

Tips to Make Your Dental Filling Last Longer

There are several steps you can take to make sure your filling continues protecting your tooth, including:

  • Visiting your dentist every six months and receiving routine X-rays and examinations
  • Be aware of and address oral habits such as clenching and grinding, which can wear-down fillings
  • Brush your teeth twice a day for two minutes and floss daily

Even though these steps seem small, they can make a big difference in your oral health. By helping you spot a failing filling early on, these preventive measures could mean the difference between an infected tooth and not!
