When you get a cavity treated, a dental filling helps restore your tooth’s strength and function. While fillings are durable, they are not designed to last forever.Daily chewing, temperature changes, and normal wear eventually cause fillings to break down.
At Aqua Dental Care, we help our Etobicoke patients stay ahead of dental problems.Knowing when a filling needs attention can help you avoid more extensive and costly treatment later.
How Long Does a Filling Usually Last?
Most dental fillings last between 5 and 15 years.The exact lifespan depends on several factors:
- The material: Silver (amalgam) fillings often last longer, while tooth-colored (composite) fillings usually last 5 to 10 years
- Wear and tear: Teeth grinding or jaw clenching can put extra pressure on fillings
- Your routine: Good brushing and flossing habits help protect the tooth around the filling
5 Signs Your Filling May Need Replacement
A filling can fail without causing obvious pain.Watch for these common warning signs:
1. Sensitivity to Hot and Cold
Sharp pain or lingering sensitivity when eating or drinking hot or cold foodsmay mean the filling has pulled away from the tooth, allowing temperature changes to reach the nerve.
2. A Visible Crack or Chip
Fillings can crack just like natural teeth.Even a small fracture can allow bacteria to enter and cause decay underneath the filling.
3. Discomfort When Chewing
Pain or pressure when biting down may indicate that the filling is loose, worn, or damaged.
4. A Rough or Sharp Texture
If your tooth feels jagged or rough when you run your tongue over it,the filling material may be wearing down or breaking away.
5. Dark Spots or Staining
Dark edges or staining around a filling can be a sign of leakage.This means the seal is compromised and decay may be forming underneath.
Why Replacing a Filling Matters
A worn or damaged filling can no longer protect your tooth.If left untreated, it may lead to:
- A larger cavity
- A cracked or broken tooth
- An infection that could require a root canal or crown
Replacing a filling early is often a simple procedure and helps preserve your natural tooth structure.
