If you've recently gotten a tooth-colored filling or are considering one for a chipped or cracked tooth, you may wonder, "How long does a filling last?" It's an important question — a good dental restoration should protect your teeth and maintain a beautiful smile for years.

At Madison Avenue Dentists, our team can answer your questions and concerns. Dual-trained prosthodontist Dr. Stella Oh estimates that composite resin fillings last about 5 – 10 years. However, the lifespan varies based on oral hygiene and lifestyle habits in New York, NY. Read more below or contact our team for an appointment.

What is a dental restoration?

Before we dive into the longevity of tooth-colored fillings, it's important to understand what a dental restoration is and why it's necessary. This kind of treatment repairs damaged teeth, or decayed teeth, or replaces missing teeth. They're necessary to restore the function and appearance of a smile.

Tooth-colored fillings, or composite resin fillings, are a dental restoration that treats cavities or minor damage. Plus, they're color-matched to your natural teeth, making them a popular choice for those seeking a more discreet option.

How long does a filling last?

As mentioned, fillings typically last between 5 – 10 years. However, this is an estimate, and the actual lifespan varies based on the following:

  • Proper oral hygiene: Regular brushing, flossing, and dental cleanings can help extend the life of your fillings. This is because good oral hygiene removes bacteria and plaque that lead to decay or damage.
  • Lifestyle habits: Habits like teeth grinding or chewing on hard objects can put extra pressure on fillings, causing them to wear down quicker. Our team may recommend a mouth guard to protect fillings.
  • Material quality: The quality of the materials used for your filling can also affect longevity. At Madison Avenue Dentists, we use only high-quality resin to ensure strong and durable dental restorations in New York, NY.

In addition to these factors, it's important to attend regular dental check-ups so our team can monitor your fillings and make any necessary adjustments or replacements before they become a bigger issue.

When to replace tooth-colored fillings

Even with the best care possible, composite resin fillings may eventually need to be replaced. These signs may indicate a need for replacement:

  • Visible wear or damage: Over time, fillings can become damaged. If you notice a chipped or cracked tooth-colored filling, have it replaced as soon as possible.
  • Discoloration: If your tooth-colored filling starts to become discolored or stained, it could mean that bacteria has seeped into the filling and caused decay. In this case, a replacement may be necessary.
  • Changes in bite or chewing: If you notice changes in the way you bite or chew after getting a filling, it could be a sign that the filling needs to be adjusted.
