When Replacing Dental Fillings Becomes Necessary

Fillings are tough, but they’re not immortal. Over time, chewing forces, temperature changes, grinding, and normal wear can cause a filling to break down. Replacing dental fillings is sometimes necessary to protect the tooth underneath and prevent bigger issues.

Here are the most common signs.

1) Cracks, chips, or rough edges

If a filling is cracked or chipped, bacteria can sneak in and cause decay under the filling. You might feel it with your tongue before you feel pain.

2) Sensitivity that doesn’t improve

Some sensitivity can happen temporarily. But if you notice increasing sensitivity to cold, sweets, or pressure, it may mean:

• The filling is leaking

• There’s decay underneath

• The tooth has a crack

3) Pain when chewing

Pain on biting can mean a filling is high, the tooth is cracked, or the filling has loosened. Either way, it deserves a look sooner rather than later.

4) Dark staining around the filling

Not all staining means decay, but it can be a clue that the edges aren’t sealed well anymore.

5) The filling is very old

Some fillings last many years, but they should still be monitored. During your exams, your dentist checks the margins, the bite, and any signs of leakage.

Why replacing dental fillings matters

A failing filling can lead to:

• New decay under the filling

• A broken tooth

• Needing a crown instead of a small repair

• Infections that can lead to root canal treatment

Final takeaway

Replacing dental fillings is about preventing a minor repair from becoming a major one. If your filling feels different, looks different, or your tooth starts acting weird, don’t ignore it.

Your tooth is trying to tell you something. It’s not being dramatic. It’s being accurate.
