Signs Your Dental Filling Needs Replacement
Signs Your Dental Filling Needs Replacement
Dental fillings are designed to restore teeth damaged by cavities and protect them from further decay. But like any dental restoration, fillings are not permanent. Over time, they can wear down, crack, loosen, or fail — sometimes without obvious symptoms.
Ignoring a failing filling can lead to deeper decay, infection, or even the need for root canal treatment. Knowing the warning signs helps you act early and protect your tooth.
Here’s what to watch for.
How Long Do Dental Fillings Last?
The lifespan of a filling depends on the material used, your oral hygiene habits, and daily wear and tear.
-
Composite (tooth-colored) fillings typically last 5–10 years
-
Amalgam (silver) fillings may last 10–15 years or longer
-
Larger fillings tend to wear out faster than smaller ones
Regular dental checkups help monitor their condition.
Common Signs Your Filling May Need Replacement
1. Tooth Sensitivity
If you experience new sensitivity to hot, cold, sweet, or pressure, it could mean the filling is worn, cracked, or pulling away from the tooth. Sensitivity often indicates microscopic gaps where bacteria can enter.
2. Pain While Chewing
Sharp pain when biting down may signal a cracked filling or tooth structure beneath it. This should be evaluated promptly to prevent further damage.
3. Visible Cracks or Chips
If you notice cracks, rough edges, or pieces of the filling missing, it needs attention. Even small fractures allow bacteria to seep underneath.
4. Dark Spots Around the Filling
Discoloration near the edges of a filling may suggest leakage or new decay forming underneath.
5. Food Frequently Getting Stuck
If food consistently gets trapped around a filled tooth, it may indicate the filling has shifted or developed gaps.
6. Loose Filling
A filling that feels loose or moves slightly is no longer sealing the tooth properly. This requires immediate replacement.
7. Persistent Bad Breath
Bacteria trapped under a deteriorating filling can cause chronic bad breath or an unpleasant taste in the mouth.
Why Fillings Fail
Several factors can shorten the life of a dental filling:
- Teeth grinding (bruxism)
- Poor oral hygiene
- Large cavity size
- Repeated pressure from chewing
- Aging dental materials
Regular dental examinations help detect early failure before symptoms worsen.
What Happens If You Delay Replacement?
A compromised filling allows bacteria to re-enter the tooth. This can lead to:
- Secondary decay
- Tooth fractures
- Infection of the pulp
- Need for root canal treatment
- In severe cases, tooth extraction
Early replacement is usually simple and prevents more extensive procedures.
The Filling Replacement Process
Replacing a filling is typically straightforward:
- The old filling is carefully removed.
- The area is cleaned to eliminate decay or bacteria.
- A new filling material is placed and shaped for proper bite alignment.
In some cases, if significant tooth structure is lost, your dentist may recommend an onlay or crown instead of another filling.
When Should You Get Your Fillings Checked?
Even if you don’t feel discomfort, fillings should be examined during routine dental visits every six months. Many issues are detected early through visual examination and digital X-rays before pain develops.
