How Long Do Composite Fillings Last?
One of the most common questions we hear at Sweet Water Dentistry is, “How long do composite fillings last?” It’s a great question—and one that reflects the natural desire patients have to invest in dental solutions that are not only safe and attractive but also long-lasting.
The good news is, composite fillings are more durable today than ever before. With advancements in materials and techniques, they can last many years with proper care. But how long exactly? Let’s explore the factors that influence the longevity of composite fillings and what you can do to make them last as long as possible.
Average Lifespan of Composite Fillings
On average, composite fillings last between 5 to 10 years. However, many patients experience even longer lifespans—sometimes up to 12 or 15 years—when the filling is well-placed and maintained with good oral hygiene and lifestyle choices.
The location and size of the filling play a big role. Fillings in areas that endure more pressure from chewing, like molars, tend to wear down faster than those on front teeth. Additionally, larger fillings that cover more of the tooth surface may not last as long as smaller ones.
What Affects the Lifespan?
Several factors influence how long your composite filling will last:
- Oral Hygiene: Brushing, flossing, and regular dental cleanings are essential. Good hygiene prevents decay around the filling and protects the surrounding tooth structure.
- Diet: Sticky, sugary, or acidic foods can weaken your fillings over time. Try to limit these and focus on a balanced, tooth-friendly diet.
- Grinding or Clenching: Bruxism (grinding teeth) places extra stress on fillings and can lead to premature wear or cracking. If you grind your teeth, ask us about a custom night guard.
- Size and Location: As mentioned earlier, larger fillings and those in high-pressure chewing areas may wear down faster.
- Dental Habits: Using your teeth to open packages, chew ice, or bite fingernails can compromise both your teeth and fillings.
Signs Your Composite Filling May Need Replacement
Composite fillings are designed to last for many years, but like all dental restorations, they don’t last forever. Here are some signs it might be time to replace yours:
- Increased sensitivity to hot, cold, or sweet foods
- Cracks, chips, or rough edges in the filling
- Discoloration or dark lines near the edges of the filling
- Pain or discomfort when biting down
- Visible wear or flattening of the surface
If you notice any of these signs, don’t wait. Catching the problem early can help prevent further damage and allow for a simple repair instead of a more involved procedure.
Can Fillings Be Repaired?
In some cases, yes. If a composite filling chips or partially wears down, your dentist may be able to repair it by adding new composite material. However, if the filling is badly worn or the surrounding tooth is compromised, a full replacement may be needed.
This is one of the advantages of composite materials—they’re often more adaptable for repairs than metal fillings.
Are Composite Fillings as Durable as Amalgam?
In the past, amalgam (metal) fillings were considered longer-lasting, especially for large back teeth. But today’s composite materials have significantly closed that gap. With the proper placement and care, composite fillings now offer similar durability, while also providing superior aesthetics and mercury-free safety.
How to Maximize the Life of Your Filling
Want your composite fillings to last as long as possible? Here are our top tips:
- Brush twice a day with fluoride toothpaste.
- Floss daily to remove plaque between teeth.
- Visit your dentist regularly for checkups and professional cleanings.
- Avoid hard foods and bad habits like chewing ice or pen caps.
- Use a night guard if you grind your teeth at night.
- Eat a balanced diet rich in vitamins and minerals for healthy teeth and gums.
