Getting a dental filling is a common and effective way to restore teeth affected by decay. However, many patients experience temporary sensitivity after the procedure. Is this normal? Yes! Here’s why it happens and how to manage it.
Why Do Fillings Cause Sensitivity?
After a filling, your tooth needs time to adjust. Common reasons for sensitivity include:
- Nerve irritation: Drilling removes decay but can disturb the nerve inside your tooth.
- Material type: Silver (amalgam) fillings expand and contract with temperature changes, while composite fillings may initially cause mild irritation.
- Bite alignment issues: If the filling is slightly high, it may create discomfort when biting down.
- Exposed dentin: If decay was deep, the exposed dentin under the enamel may be sensitive to hot, cold, or sweet foods.
How Long Does Sensitivity Last?
- Mild sensitivity can last a few days to a few weeks.
- If discomfort persists, contact your dentist to check for issues like improper bite alignment.
Tips for Managing Sensitivity
- Avoid extreme temperatures – Skip overly hot or cold drinks for a few days.
- Use desensitising toothpaste – Brands like Sensodyne or Colgate Sensitive help reduce discomfort.
- Chew on the opposite side – Give the filled tooth time to settle.
- Take pain relievers if needed – Over-the-counter medications can ease discomfort.
- Contact your dentist – If pain worsens or lasts too long, a quick adjustment may be needed.
When to Be Concerned
While mild sensitivity is normal, sharp or prolonged pain could indicate:
- A filling that needs adjustment.
- A potential crack in the tooth.
- An issue with the nerve, possibly requiring a root canal.
Final Thoughts
Post-filling sensitivity is common and usually temporary. Following simple care steps and monitoring your symptoms can ensure a smooth recovery and enjoy a stronger, healthier tooth.
