A tooth filling is supposed to relieve pain, not cause it. But what if your filling starts hurting months later? This discomfort can be alarming, leaving you wondering if something is wrong.
According to the American Dental Association (ADA), about 50% of adults have at least one dental filling. While most fillings work perfectly, some may cause lingering pain due to various reasons.
In this guide, we’ll explore why your tooth filling hurts after months, when to worry, and how to fix it. Let’s dive in!
Normal Sensitivity vs. Persistent Pain
After a filling, mild sensitivity to hot or cold foods is normal. This usually fades within a few weeks. However, persistent pain months later is not normal and may signal an underlying issue.
Why Sensitivity Occurs
- The filling process irritates the tooth nerve temporarily.
- Deep fillings may cause prolonged sensitivity.
When to Worry
- Throbbing pain that worsens over time.
- Pain when biting down.
- Swelling or fever (signs of infection).
If your pain lasts beyond two weeks, consult your dentist immediately.
Common Reasons Your Tooth Filling Hurts After Months
Improper Bite Alignment
If your filling is too high, it creates uneven pressure when chewing. Over time, this strains the tooth and surrounding tissues, causing pain.
Solution:
- Visit your dentist for bite adjustment.
- They will reshape the filling for a proper fit.
Tooth Decay Under the Filling
Sometimes, decay isn’t fully removed before filling. Bacteria can sneak in, causing new decay and pain.
Solution:
- An X-ray can detect hidden decay.
- The dentist may replace the filling if necessary.
Cracked or Loose Filling
Fillings can wear out, crack, or loosen over time. This exposes the tooth to bacteria, leading to sensitivity or infection.
Solution:
- Schedule a dental checkup.
- The dentist will repair or replace the filling.
Nerve Irritation or Damage
Deep fillings may inflame the tooth’s nerve (pulp). If untreated, this can lead to irreversible pulpitis, requiring a root canal.
Solution:
- Early treatment can save the tooth.
- A root canal may be needed in severe cases.
Allergic Reaction to Filling Material
Rarely, patients react to metals in amalgam fillings or resins in composite fillings.
Solution:
- Discuss alternative filling materials with your dentist.
When to See a Dentist
Ignoring filling pain can lead to serious complications. Seek immediate dental care if you experience:
- Severe, throbbing pain.
- Swelling in the gums or face.
- Fever or foul taste (signs of infection).
Early intervention prevents costly treatments later.
How to Prevent Filling Pain
Actionable Tips
- Maintain good oral hygiene (brush twice daily, floss).
- Avoid chewing hard foods on the filled tooth.
- Use desensitizing toothpaste if needed.
- Visit your dentist for regular checkups.
