Dental fillings remain one of the most reliable restorative forms of treatment when treating decay. When a cavity occurs that threatens the future function and viability of a tooth, these custom creations can deliver optimal protection. But how long do they last? Are they permanent, and if not, what can you do to make sure they last as long as possible? Keep reading to discover what tips and tricks you can use to extend the lifespan of your dental fillings.
What is the Average Lifespan of a Dental Filling?
The lifespan of a dental filling is dependent on a few factors, such as:
- The material used (i.e., amalgam, composite resin, gold, porcelain, etc.)
- The level of care and attention you provide once a filling is in place
- The trauma your tooth experiences
- Whether you practice bad oral habits, like teeth grinding
Generally, the material you and your dentist in Canton choose will be the clearest indicator of how long your filling will last. If using amalgam or ceramic, a crown might endure 15 years before needing replacement, while composite fillings may remain in place for 7-10 years.
When Should One Be Replaced?
Following the average timeframes for fillings can be helpful, but it’s more important to recognize the signs that indicate it’s time for a replacement. During a dental checkup, you can expect your dentist to tell you if one or more of your fillings need to be changed out, but you may notice a few symptoms before your appointment, such as:
- A noticeable crack or damage
- The filling moves when touched
- The filling falls out
- Possible pain forming because of bacteria that have re-entered the space
- Increased tooth sensitivity when eating or drinking hot or cold foods or beverages
How Should You Take Care of Your Dental Filling?
To make sure your dental filling remains firmly in place, you’ll need to stay on top of your oral hygiene routine. It’s too easy for bacteria to penetrate the tooth should a filling become loose over time. Regular brushing (twice daily) for two minutes, flossing at least once, and rinsing with antimicrobial mouthwash will flush out harmful plaque and tartar.
You’ll also need to:
- Keep your regularly scheduled dental checkups and cleanings with your dentist
- Avoiding biting down on anything hard (i.e., food, inanimate objects, ice, etc.)
- Wearing a custom nightguard if you grind or clench your teeth at night
While fillings are not designed to last a lifetime, they can stay in place for one or two decades if you commit to taking care of your smile.
