If you’ve ever needed a tooth repaired, you may have wondered: How long do dental fillings last? The answer isn’t the same for everyone. The type of material used, your oral hygiene routine, diet, and even whether you grind your teeth all influence the dental filling lifespan.

At Bare Smiles Dental Boutique in Essendon, we see many patients from Moonee Ponds, Strathmore, Niddrie, and across Melbourne who ask this very question. Here’s everything you need to know about the longevity of tooth fillings and how to make yours last as long as possible.

Average Lifespan of Dental Fillings

So, how long do dental fillings last on average? It depends on the material and where the filling is placed in the mouth:

Filling Material	Expected Lifespan
Composite (Tooth-Coloured)	Composite fillings are popular for their natural appearance. On average, they last 5–10 years. They are ideal for front teeth or areas where aesthetics matter most, but they may wear down faster on chewing surfaces.
Amalgam (Silver)	Amalgam fillings are made from a durable metal blend. They can last 10–15 years or longer, making them highly reliable for back molars exposed to heavy chewing.
Glass Ionomer Cement (GIC)	Glass Ionomer Cement (GIC) fillings are often used for temporary or non-load-bearing areas. They typically last 2–5 years, but they release fluoride, which helps protect the tooth.
Ceramic Fillings	Ceramic (porcelain) fillings are highly aesthetic and resistant to staining. Their lifespan is usually 10–15 years, though they can be more brittle if placed under heavy pressure.
Gold Fillings	Gold fillings are less common today, but extremely long-lasting. With proper care, they can last 15–20 years or more. Gold is strong, biocompatible, and resistant to wear.

What Affects the Longevity of a Dental Filling?

Several factors influence how long dental fillings last:

🦷 Material Type

Amalgam and gold fillings generally outlast composite or GIC.

🦷 Tooth Location

Molars face heavy chewing pressure, reducing lifespan.

🦷 Oral Hygiene

Regular brushing, flossing, and check-ups extend your dental restoration.

🦷 Bite & Bruxism

Grinding (bruxism) can fracture fillings; a night guard protects them.

🦷 Diet

Sugary or acidic foods and chewing hard objects can shorten filling life.

Signs Your Filling May Need Replacing

Even strong fillings don’t last forever. Look out for these signs of filling replacement:

• Sensitivity to hot, cold, or sweet foods

• Pain when chewing or biting

• Cracks, chips, or gaps around the filling

• A loose or rough surface

• Discolouration around the edge of the filling

If you notice any of these, book an appointment at Bare Smiles Dental Boutique in Essendon. Early filling replacement prevents further decay or more invasive treatments like crowns or root canals.

How to Extend the Life of Your Dental Fillings

Want to make your tooth fillings last longer? Here are proven tips:

✅ Brush twice daily with fluoride toothpaste

✅ Floss daily to clean around filling margins

✅ Avoid hard or sticky foods like nuts, ice, and caramels

✅ Wear a night guard if you grind your teeth

✅ Schedule routine dental check-ups every 6–12 months

✅ Avoid chewing on pens or fingernails

Small lifestyle changes can dramatically extend the dental filling lifespan, saving you time, money, and discomfort.

How Often Should You Replace a Filling?

Patients often ask not only how long do dental fillings last but also how often they should be replaced. There’s no fixed timeline. Instead, fillings should be checked regularly during routine exams.

• If the filling is still intact and functional, no replacement is needed.

• If it’s cracked, worn, or loose, prompt filling replacement prevents bigger problems.

  
  

On average, most fillings will eventually need replacement after 7–15 years, depending on the material.
