Yes, dental fillings aren’t meant to last forever. Over time, they can wear down, crack, or become loose — which is why regular dental checkups are so important.
Here’s what Canadian patients should know about replacing fillings.
⌛ How Long Do Fillings Last?
- Composite (tooth-coloured) fillings: 5 to 10 years
- Amalgam (silver) fillings: 10 to 15 years
- Gold or ceramic inlays/onlays: Can last even longer with proper care
The lifespan depends on:
- The size and location of the filling
- Your oral hygiene habits
- If you grind or clench your teeth
🚑 Signs a Filling May Need to Be Replaced
- Sensitivity to hot, cold, or sweets
- A visible crack or chip in the filling
- Pain when biting or chewing
- The filling feels loose or rough
- Decay developing around the edges
🥺 Why Replacement Matters
Worn or damaged fillings can allow bacteria to sneak in, leading to:
- Tooth decay beneath the filling
- Infection or abscess
- A possible need for a root canal or crown
Catching issues early can save time, discomfort, and cost.
🛌 What Happens During a Replacement?
The dentist will:
- Remove the old filling
- Clean the area and check for any decay
- Place a new filling, matched to your tooth
It’s usually a quick and painless process.
