Fillings play a vital role in keeping your teeth healthy, but they’re not built to last forever. After a few years, they start to wear out—sometimes slowly, sometimes all at once, and that’s when trouble can begin. Cavities, sensitivity, or just that annoying spasm-like pain when you bite foods—all signs that your old fillings might be past their prime. So, when should you swap them out? Let’s talk about the warning signs and why getting ahead of the problem matters for your teeth.

Why Are Fillings Important?

Fillings patch up the damage left by cavities. They protect the sensitive parts of your tooth and prevent bacteria from entering. Still, fillings age just like anything else. Over time, they can lose their grip, crack, or wear down, leading to more serious dental problems.

How to Tell If You Need a New Filling

Fillings can fail due to a variety of reasons. The most common ones are:

1. Cracks or Chips

If you spot a crack or chip in your filling, don’t ignore it. Even a hairline fracture lets bacteria hide under the surface, where they can do real damage. The longer you ignore it, the worse it gets.

2. Sensitivity or Pain

A filling that’s worn down or not sealing the tooth right can make your mouth sensitive. Hot coffee, cold drinks, and even biting into something sweet can trigger it. Sharp pain when chewing? That’s a common sign that something’s wrong with your oral health.

3. Loose or Missing Filling

If your filling falls out, call your dentist right away. Without it, your tooth is wide open to decay and infection.

4. Decay Around the Edges

Sometimes, decay starts forming right where the filling meets the tooth. It’s not always easy to spot on your own, which is why regular check-ups matter. If your dentist sees new decay, it’s time for a replacement.

5. Discoloration

Fillings that look dark or stained might no longer be doing their job. Sometimes it’s just a cosmetic thing, but if your smile is starting to change, your filling could be the culprit.

How Long Do Fillings Last?

Dental fillings have different shelf lives based on the materials they’re made of. Silver (amalgam) ones usually last about 10–15 years. Tooth-colored composite fillings are a bit less durable—expect them to last 5–7 years on average. Your daily habits and where the filling sits in your mouth also play a role, so your dentist’s advice matters most.

Different Fillings, Different Lifespans

Let’s break it down:

• Amalgam (silver): Tough, affordable, and long-lasting—often lasts over 10 years.
• Composite (tooth-colored): Blend in nicely with your teeth, but need replacing after 5 to 10 years.
• Ceramic: Looks great and lasts up to 15 years, but they’ll cost more.
• Gold: Some last 20 years or more, but they’re pricey.

What’s It Like to Get a Filling Replaced?

It’s straightforward. Your dentist removes the old filling, cleans out any decay, and then puts in new material that matches your tooth. Most of the time, you’re done in one visit.

Why Bother Replacing Fillings on Time?

Replacing old fillings before they fall out keeps your teeth strong and prevents extensive problems from developing. Catch issues early, and you can skip the pain (and expense) of root canals or crowns down the road. Plus, your teeth look and work better, so you keep your smile in shape.

Putting off filling replacements might not seem like a big deal, but it adds up over time. Regular dental visits help you catch problems early and keep your fillings doing their job.
