Warning Signs Your Filling Is Wearing Out
If you’ve had a filling for a few years, you’ve probably never given it a second thought. That’s exactly how it should work. But fillings aren’t permanent. Depending on the material and how much wear your bite puts on it, a filling can last anywhere from 5 to 15 years, and sometimes longer. Once it starts to break down, the same tooth that the filling protected can be at risk all over again.
At Larson Dental, Dr. Seth Larson and Dr. Zack Larson see patients throughout Prescott Valley whose old fillings are due for a look. Catching the warning signs early usually means a simple, straightforward fix. Waiting too long can mean a bigger, more expensive procedure down the road. Here are five signs it may be time to have your filling checked.
Notice any of these? Call Larson Dental at (928) 772-8128, and we’ll take a look.
1. Visible Cracks or Chips
Run your tongue over an old filling and something feels off — a rough edge, a small notch, a piece that seems to be missing entirely. Even a hairline crack in a filling is a problem, because it gives bacteria and food particles a direct path underneath the material and into the tooth itself. Once decay starts developing under a filling, it’s often hidden from view and can progress for a while before you notice anything else is wrong. If a filling looks anything less than smooth and intact, it’s worth having it examined.
2. Sensitivity to Hot, Cold, or Sweets
A little sensitivity right after a filling is placed is normal and usually fades within a few weeks. Sensitivity that shows up later or comes back after years of the tooth feeling fine is a different story. It often means the seal between the filling and the tooth has started to break down, letting temperature changes and sugars reach the nerve underneath. Mild, occasional twinges are worth mentioning at your next cleaning. Sharp or lingering pain, especially if it’s isolated to one tooth, deserves a sooner look, since it can also point to decay that’s already reached deeper into the tooth.
3. Visible Gaps or Dark Staining Around the Filling
Look closely at the edge where the filling meets your natural tooth. A dark line, a stained margin, or a visible gap along that border can be a sign that decay has already started underneath — even if the rest of the filling looks fine. Gaps also give food and plaque somewhere to collect, which only speeds up the problem. This is one of the harder signs to catch on your own, which is part of why routine checkups matter: a dentist can spot a failing margin with a simple visual exam and X-rays long before it becomes something you’d notice or feel.
4. Pain When Biting or Chewing
Discomfort when you bite down can mean a few different things. Sometimes a filling has shifted slightly or sits a little too high, throwing off your bite. Other times, it’s a sign the filling itself has cracked under the pressure of chewing. Pain with biting can also indicate a crack in the tooth structure surrounding the filling, which is a more urgent issue since an untreated cracked tooth can lead to infection or the need for a root canal. Either way, biting pain isn’t something to wait out. It’s worth having evaluated promptly.
5. The Filling Is Old — Especially If It’s Metal
Even a filling with no obvious symptoms can be due for a replacement based on age alone. Amalgam (silver) fillings are durable and can last for decades, but they do eventually wear down. Composite (tooth-colored) fillings typically hold up for around 5 to 10 years before they may need replacement. If you’re not sure how old a filling is, or it’s been a long time since your last dental exam, that’s reason enough to have it checked — plenty of fillings fail quietly, with no pain at all, until the decay underneath has already spread.
What Happens If You Wait Too Long
A failing filling rarely stays a small problem if it’s ignored. Decay that develops underneath can spread further into the tooth, eventually reaching the nerve and requiring root canal therapy, or weakening the tooth enough that it needs a dental crown instead of a simple filling replacement. Catching these five signs early is almost always the difference between a quick, comfortable fix and a longer, more involved treatment.
