Dental fillings are like quiet little heroes in your mouth. They seal out decay, restore strength, and allow you to chew, smile, and enjoy life without thinking about them—until one day, they need a bit of attention.
If you live in Riverside, you probably have plenty of other things on your mind besides your dental work. But ignoring an aging filling can lead to bigger problems down the road. At Riverside Dental Center, we want to help you catch the early signs so your teeth stay healthy and pain-free.
In this article, we’ll walk you through how to know when it’s time to replace a filling, share some insights from our dental team, and give you practical tips to keep your fillings strong for years.
Why Fillings Don’t Last Forever
Even the most well-done filling has a lifespan. Fillings are exposed to constant pressure from chewing, grinding, temperature changes, and even the foods and drinks you consume. Over time, they can wear down, crack, or loosen.
It’s a bit like a road repair—at first, the patch is solid, but years of traffic eventually wear it out. The key is to spot small issues early before they turn into full-blown potholes (or cavities!).
Signs Your Filling Might Need to Be Replaced
If you’re wondering whether an old filling might be due for a replacement, here are some clues to look for:
1. Tooth Sensitivity or Pain

A sudden zing of sensitivity when drinking hot coffee or biting into cold ice cream might mean your filling is failing. This can happen if the seal between the tooth and filling has weakened, letting in bacteria or temperature changes.
2. Visible Wear or Cracks
Sometimes you can see the problem yourself. If your filling looks chipped, cracked, or has a gap, it’s time for a professional check.
Tip from Dr. Patel at Riverside Dental Center: “Don’t wait for pain to schedule a visit. A cracked filling can let bacteria sneak in quietly. Replacing it early can prevent a much larger restoration later.”
3. Rough or Sharp Edges
Run your tongue along the filling. Does it feel smooth, or are there rough edges? A rough edge can indicate wear or damage.
4. Food Getting Stuck

If food is suddenly catching between teeth that used to feel smooth, your filling may have shifted or worn down. This can create tiny spaces where bacteria love to hide.
5. Changes in Bite or Chewing
Does your bite feel different than it used to? Sometimes fillings wear unevenly, changing how your teeth come together.
What Happens If You Ignore It?
Here’s the truth: a worn-out filling is not just a cosmetic issue. Once a filling fails, the tooth underneath is no longer protected. This can lead to:
- New cavities under the filling
- Tooth fractures
- Infection that may require a root canal
- More extensive (and expensive) repairs
Think of it like ignoring a small roof leak—it may seem harmless now, but over time, the damage spreads.
How Long Do Fillings Usually Last?

The lifespan of a filling depends on its material and how well it’s cared for:
- Composite (tooth-colored) fillings: Typically last 5–10 years
- Amalgam (silver) fillings: Can last 10–15 years or more
- Gold or ceramic inlays/onlays: Can last 15–20+ years
Good oral hygiene, regular checkups, and avoiding habits like chewing ice can extend the life of any filling.
A Real-Life Riverside Story
At Riverside Dental Center, we see many patients who are surprised to learn their fillings need replacing. One patient, a longtime Riverside resident, came in for a routine cleaning. She wasn’t in pain, but Dr. Patel noticed tiny cracks around one of her back molar fillings.
Because she caught it early, we were able to replace the filling in a single visit—saving her from a future crown or root canal. Her story is a good reminder that dental issues don’t always announce themselves with pain.
How We Check Fillings at Riverside Dental Center

When you visit our office, we check your fillings using:
- Visual inspection: Looking for cracks, wear, or gaps
- Dental instruments: Gently checking for soft spots or loose edges
- Digital X-rays: Identifying hidden decay under or around the filling
These tools allow us to catch problems before they become bigger issues.
Tips to Make Your Fillings Last Longer

While no filling lasts forever, you can help extend their lifespan:
- Brush twice a day with fluoride toothpaste – Keeps enamel and filling edges strong.
- Floss daily – Prevents plaque from sneaking between teeth and around fillings.
- Avoid chewing hard objects – Ice, pens, and hard candy are tough on fillings.
- Wear a nightguard if you grind your teeth – Grinding puts extra stress on fillings.
- See your dentist regularly – Early detection is key.
