How Long Do Composite Fillings Last?
If you’ve ever had a cavity, chances are you’ve received a filling. Composite fillings, also called tooth-colored fillings, are a popular choice because they blend seamlessly with natural teeth. But how long do they actually last? The answer depends on a few factors, including your oral habits and how well you care for them.
The Lifespan of Composite Fillings
On average, composite fillings last 5 to 10 years. However, with proper care, some can last even longer. Unlike traditional silver fillings, composite material bonds directly to the tooth, offering a strong and natural-looking restoration. While durable, composite fillings aren’t as resistant to wear as metal fillings, so they may need replacement sooner. Their longevity depends on several factors, including:
- The size of the filling – Smaller fillings tend to last longer than larger ones.
- Where the filling is located – Fillings on molars experience more pressure from chewing, which can wear them down faster.
- Oral hygiene habits – Brushing, flossing, and regular checkups help prevent decay around the filling.
- Diet and lifestyle choices – Sugary foods, acidic drinks, and habits like teeth grinding can shorten a filling’s lifespan.
Some patients keep their composite fillings for well over a decade with good oral care and routine dental visits.
Signs Your Filling Needs to Be Replaced
Even the best fillings don’t last forever. Watch for these signs that yours may need attention:
- Tooth Sensitivity – Increased sensitivity to hot, cold, or sweets could mean your filling is wearing down.
- Pain When Chewing – If biting down causes discomfort, your filling may be cracked or loose.
- Visible Wear or Discoloration – Dark spots or rough edges may indicate that a filling needs repair.
- Gaps Between the Filling and Tooth – Bacteria can enter these spaces and lead to decay.
If you notice any of these symptoms, schedule an appointment to have your filling checked.
Extending the Life of Your Fillings
While fillings naturally wear over time, you can make them last longer with good habits:
- Brush twice a day with fluoride toothpaste.
- Floss daily to prevent decay around the filling.
- Avoid chewing ice, hard candies, or non-food objects like pens.
- Wear a night guard if you grind your teeth.
- Visit your dentist regularly for checkups and cleanings.
