And Why a Crown Might Be the Better Solution
Knowing when to replace a dental filling is critical to a healthy smile.
It’s easy to assume that if a filling cracks, wears down, or falls out, the solution is just… another filling. But in many cases, a compromised filling is a red flag that your tooth needs stronger support, and the best long-term protection often comes in the form of a full-coverage dental crown.
So before you ask your dentist for a “quick filling fix,” here’s what you should know.
Fillings Don’t Last Forever, And Neither Does Tooth Structure
Dental fillings do a great job of restoring teeth after cavities, but they aren’t permanent. Over time, they break down due to daily wear, chewing forces, and even clenching or grinding. But here’s the real problem: by the time a filling needs to be replaced, the tooth around it may be compromised, too.
That means there’s often not enough healthy structure left to safely support another filling, especially if the original one was large. Trying to “patch” it again can lead to cracks, fractures, or even tooth loss down the road.
5 Signs When To Replace A Dental Filling
If you’re experiencing any of these issues, it’s a sign the restoration—and possibly the tooth itself—needs a more permanent solution:
1. Tooth Sensitivity or Pain
Pain when chewing or sensitivity to hot, cold, or sweet foods often means the tooth is exposed or inflamed beneath a broken filling.
2. Cracks or Rough Edges
Cracked fillings or teeth can’t be repaired with another filling. They need coverage to keep the tooth from splitting.
3. A Loose or Missing Filling
Once a filling falls out, the tooth is vulnerable to bacteria, decay, and structural damage.
4. Discoloration Around the Filling
Staining or dark areas near a filling could mean it’s leaking—or worse, hiding decay underneath.
5. Changes in Your Bite
If your bite feels off or your tooth feels “different” when chewing, the structural integrity may already be compromised.
Why Crowns Are Often the Right Solution
A dental crown is a full-coverage restoration that acts like a protective helmet for your tooth. Instead of filling a damaged area, a crown wraps around the entire tooth, restoring its shape, strength, and function.
When an old filling fails, especially a large one, it usually means the tooth has been weakened. In this case, placing another filling might just delay the inevitable. A crown, however, reinforces the tooth and can prevent cracks, sensitivity, and future root canals.
