Fillings are the standard treatment for small cavities. The process is fast, and the results are reliable. But how long do dental fillings last? Can you expect your new restoration to stand the test of time, or will you need to get it replaced relatively frequently? In this blog post, you will learn about the average lifespan of fillings and discover tips to help yours last as long as possible.

The Average Lifespan of Dental Fillings

On average, dental fillings last 5 – 15 years before they need to be replaced. Metal fillings tend to last the longest. However, many patients dislike them because of their dark color and the fact that they can be composed of up to 50% mercury.

The most common type of filling, tooth-colored composite resin fillings, often last 5 – 7 years, though they can endure for even longer in some cases. These restorations blend in beautifully with the surrounding enamel and are completely metal-free.

Make Your Fillings Last

There are some practical steps you can take that may help your fillings last as long as possible:

  • Brush your teeth twice daily with a soft-bristled toothbrush and fluoride toothpaste to maintain oral hygiene.
  • Floss at least once a day to remove plaque and food particles from between your teeth and around your fillings.
  • Limit your consumption of sugary and acidic foods, as these can damage both natural enamel and fillings.
  • Visit your dentist regularly for professional cleanings and checkups to monitor the condition of your fillings.
  • Avoid chewing on hard objects, such as ice, pens, or fingernails, which may crack or damage your restorations.
  • Rinse your mouth with water after consuming snacks or beverages that may leave residue on your teeth.

When to Replace Your Fillings

How can you tell when a filling needs to be replaced? Your dental team will check your restorations during routine examinations, and they will let you know if they notice signs that a filling is going to fail soon.

Other indications that you might need to get your filling replaced include:

  • A filling has fallen out (you may notice a pit or hole in your tooth where a filling used to be).
  • A tooth with a filling has become extra-sensitive or is causing pain.
  • Food particles frequently get stuck around your filling.
  • You notice visible damage to the filling or the surrounding dentition.

Fillings are a long-term solution to cavities, but they do not last forever! Be sure to visit your dentist regularly so you can maintain a strong smile.
