Do Dental Fillings Need to be Replaced?
December 10, 2025

Dental fillings are one of the most common and effective ways to treat cavities and protect teeth from further damage. But even though they’re durable, they’re not designed to last forever. At Waldo Dental Care, we believe that understanding the lifespan of your dental work is key to maintaining a healthy, confident smile.
If you’re wondering whether your fillings need to be replaced, you’re not alone. We’re here to help you feel informed and at ease about your next steps.
How Long Do Dental Fillings Last?
The longevity of a filling depends on several factors, including the type of material used, your oral hygiene habits, and the amount of wear your teeth experience. Most fillings don’t last a lifetime, but with proper care and regular dental visits, they can serve you well for many years. Here’s a general guideline on how long different fillings may last:
- Composite (Tooth-Colored) Fillings: Typically last 5-10 years
- Amalgam (Silver Metal) Fillings: Often last 10-15 years or longer
Your lifestyle, such as grinding your teeth (bruxism) or consuming hard foods regularly, can also impact how long your fillings stay intact. That’s one reason why Waldo Dental Care takes the time to understand your habits and tailor your dental care accordingly.
Signs That Your Filling May Need to Be Replaced
Even if you’re not experiencing discomfort, there could be subtle signs that a filling is failing. Regular dental checkups are your first line of defense. They make it easier for your dentist to detect early changes. Here’s what to watch for:
- Tooth sensitivity to temperature or sweets
- Visible cracks, chips, or wear in the filling
- Pain or discomfort when biting down
- Discoloration around the filling
- A feeling that the filling is loose or "off"
If you notice any of these issues, it’s time to let your dentist evaluate the filling. At Waldo Dental Care, our team takes a gentle, judgment-free approach, ensuring you feel comfortable while we examine and explain your treatment options.
Why Replacing Old Fillings Matters
Putting off a necessary filling replacement can lead to more serious dental issues. When a filling starts to fail, bacteria can sneak into tiny gaps and cause decay beneath the surface. This often happens without immediate symptoms. Replacing aging or damaged fillings helps prevent the need for more complex (and costly) procedures like root canals or extractions. It also:
- Preserves the strength of your natural tooth
- Restores function and comfort for chewing
- Enhances the appearance of your smile, especially with tooth-colored materials
Our Kansas City team offers high-quality, long-lasting materials and takes pride in our award-winning craftsmanship, ensuring that your dental restorations not only perform well but look beautiful, too.
