You’ve got a silver dental filling in the back of your mouth. It’s been there since college. It doesn’t hurt. It doesn’t bother you. So you figure, why mess with it? That’s a fair question. And honestly? We hear it all the time at Seaside Family & Cosmetic Dentistry in Hampstead.
But dental fillings aren’t like fine wine. They don’t get better with age. And waiting until one hurts or falls out is usually the most expensive way to handle it. Let’s talk about what happens to older fillings, and why being proactive often saves you time, money, and discomfort.
Dental Fillings Have a Shelf Life
Most fillings last between 5 and 15 years. That’s a big range, we know. It depends on a bunch of stuff: how big the filling is, where it is in your mouth, how hard you bite, and how well you take care of it.
But a filling that’s 15 years old is already on borrowed time. Even if it looks fine to you, there’s a lot going on underneath that you can’t see.
What’s Actually Happening Under There?
That filling has been through thousands of meals, hot coffees, and ice-cold drinks. Every time you bite down, there’s tiny pressure on it. Over a decade and a half, that pressure adds up.
Your tooth also expands and contracts a little with temperature changes. The metal in an old silver filling does the same thing, but at a slightly different rate. Over time, that can create microscopic gaps between the filling and your tooth. Bacteria love those gaps. They sneak in, multiply, and start causing decay underneath the filling. You can’t see it. You can’t feel it at first. But it’s there, quietly getting worse.
Signs Your Filling Might Be Done
Sometimes there are clues. Keep an eye out for:
- A dark line around the edge: That’s often stain or early leakage. Not always a crisis, but worth checking.
- Roughness when you run your tongue over it: That can mean the filling is wearing down or cracking.
- Pain when you bite down: That’s a big red flag. It could mean the filling is loose or the tooth underneath is fractured.
- Sensitivity to sweets or cold: This can mean decay has reached a deeper layer of your tooth.
- The filling just falls out: This happens. Usually at dinner. Usually when you’re not expecting it.
The “Wait and See” Gamble
Nobody wants to get a filling replaced just for fun. We get that. But replacing a worn-out filling early might take 30 minutes and cost a few hundred dollars. Waiting until that tooth cracks or needs a root canal? That’s multiple visits, more time off work, and a bill that could be three or four times higher.
It’s like changing the oil in your car. You can do it now, or you can wait until the engine seizes. One of those options is a whole lot more painful.
What Does Replacing a Filling Look Like?
It’s honestly not a big deal. Dr. Francis or Dr. Fuller will numb the area, remove the old filling, clean out any decay, and place a new one. These days, most people choose tooth-colored composite fillings that blend right in, even for back teeth.
You’re in and out in one appointment, and your tooth gets a fresh start.
Don’t Guess. Let Us Look
The tricky thing about old fillings is that you can’t see the whole picture. A quick exam and an X-ray can show us exactly what’s happening underneath the surface. If your filling is 15 years old, or even just getting close, it’s worth having us take a peek. If it’s fine, we’ll tell you it’s fine. No surprises. No pressure. Just honest answers.
