Let’s Clear the Air:
I hear this one almost every week in my chair:
“Doc, now that I’ve got a filling, I’m good for life… right?”
I wish I could tell you “Yes, forever!” and send you off into a cavity-free sunset. But here’s the truth dental fillings aren’t forever.
So, How Long Do They Actually Last?
It depends on a few things:
- Type of filling material – Composite (tooth-colored) fillings usually last 5–10 years. Silver amalgam fillings can push 10–15 years or more.
- Where it’s placed – A filling in your chewing molar wears down faster than one in a front tooth.
- Your daily habits – Teeth grinding, biting nails, or chewing ice? You’re basically giving that filling an early retirement.
Why Fillings Don’t Last Forever
Over time, your filling takes a beating chewing, temperature changes, and pressure cause tiny wear and tear. This can create gaps between the filling and tooth, allowing bacteria to sneak in. And guess what? That means the cavity can come back.
Signs Your Filling Might Need a Checkup
- Sensitivity to hot, cold, or sweet foods
- Pain when biting down
- A visible crack or chip in the filling
- Feeling like something’s “off” when you run your tongue over it
If you notice any of these, don’t wait. A small repair now can prevent a bigger procedure later.
How to Make Fillings Last Longer
- Brush twice daily with fluoride toothpaste
- Floss daily (yes, really)
- Avoid chewing hard objects
- Keep up with your dental checkups — we spot problems before they hurt
Dr. Kalpesh’s Final Word
Fillings are strong, reliable, and can last years — but they’re not a one-and-done deal. Think of them like a car: take care of them, and they’ll take care of you. Ignore them, and, well… you might be seeing me sooner than you’d like.
