If you’ve had a cavity filled in the past, you may be asking yourself how long that filling will stay in your mouth. This is something many patients ask during their dental check-ups with their dentist in Winnipeg. Dental fillings were designed for strength and longevity, but they aren’t permanent solutions. In this blog, we’re hoping to get you clear on the average life expectancy of fillings, how to know when your fillings need replacing, and how to care for your dental fillings to maintain their integrity for the longest amount of time.
What Factors Affect How Long a Dental Filling Lasts?
Multiple factors impact the longevity of dental fillings.
Material—Fillings can be made of a variety of materials—amalgam (silver), composite (tooth-coloured), gold, and ceramic. Each material has its life expectancy:
- Amalgam—$10-15 years
- Composite—5-10
- Gold—up to 15 years or more
- Ceramic—still frequently lasting 15 years or more with great maintenance!
Location—If the filling is located in an area that is under heavy biting forces, such as molar teeth, the filling will likely fail sooner than if the filling were in an area that does not provide the same chewing force.
Oral Habits—Biting nails, grinding teeth, and chewing on ice and hard candies could damage/deteriorate your filling.
Oral Hygiene—Daily brushing and flossing, along with regular dental visits, can keep your fillings in better shape for longer.
How Long Do Dental Fillings Last on Average?
For a better understanding, consider this brief comparison:
| Type of Filling | Average Lifespan |
| Amalgam (Silver) | 10–15 years |
| Composite (White) | 5–10 years |
| Gold | 15+ years |
| Ceramic | 15+ years |
While these are averages, it’s not uncommon for some fillings to last even longer if cared for properly.
When Should You Replace Dental Fillings?
Fillings can weaken over time due to regular wear and tear, and it is necessary to understand when to replace dental fillings so that your teeth are not weakened further. Among the warning indicators to watch out for are
- Sensitivity of the tooth—Sudden sensitivity to hot, cold, or sweet foods might be a sign that your filling is compromised or leaking.
- Pain or Discomfort—The filling will be loose or cracked if there is a sudden pain when chewing or biting.
- Visible Cracks or Wear—If your filling is worn or cracked when you check in the mirror, it might need to be replaced.
- Decay Around the Filling—Existing fillings may become surrounded by new deterioration. Frequent examinations will identify this early.
- Filling Falls Out—This is a definite warning; it must be replaced. Don’t try to pretend you don’t feel it—see your dentist right away.
You must visit your dentist regularly, even when you have no discomfort. Sometimes fillings must be replaced before symptoms even begin.
How Can You Make Your Fillings Last Longer?
The following simple advice will help you safeguard your fillings:
- Fluoride toothpaste should be used twice daily.
- Floss every day to remove food between your teeth.
- Don’t chew on hard things like pencils, ice, or nails.
- Go see your dentist every six months for cleanings and exams.
- Wear a mouthguard at night if you clench your teeth.
- Little habits can add up to make a big difference in how long your fillings will last!
