Dental fillings are a common way to repair a tooth that has a cavity. And the answer to how long a dental filling lasts depends on the material used and your daily oral health habits. Dental fillings help protect your tooth from more decay and are a key part of restorative dental care that restores its function.
Fillings are strong, and most last for a long time, but they don’t last forever. Regular dental exams and cleanings help keep your teeth in good condition, so your smile stays healthy. These appointments also give your dentist a chance to ensure everything else in your mouth is okay.
A Look at Different Types of Fillings & Their Lifespans
There are several materials used for fillings, and each has a different typical lifespan. Your dental team can help you choose the right one for your needs. This choice often balances appearance, strength, and cost.
Composite Fillings
These are also known as tooth-coloured fillings because they blend in with your natural teeth. They are a popular choice for visible teeth because they look so natural, much like other cosmetic options such as bonding and veneers. With proper care, they can last 7–10 years.
Amalgam Fillings
Also called silver fillings, these are very durable and have been used for a long time. You can often expect an amalgam filling to last for 10–20 years. Sometimes they can last even longer with good care.
Gold & Ceramic Fillings
Gold and ceramic (or porcelain) fillings are known for their strength and longevity. Both types can last 15–20 years or more. They are a strong option for restoring your teeth.
Factors That Affect Your Filling’s Lifespan
The material of your filling is just a piece of the puzzle. Several other factors can affect how long your filling lasts over time. Your daily actions play a large part in the health of your dental work.
- Your oral hygiene habits: Brushing twice a day and flossing daily help prevent new decay from forming around the edges of your filling
- Your diet: Frequent consumption of sugary, sticky, or hard foods can put stress on your fillings and teeth
- Teeth grinding: If you grind or clench your teeth, it can cause fillings to wear down or crack more quickly
- Trauma or injury: A knock to the mouth or biting down on something hard can damage a filling
Signs You Need a Replacement Filling
It’s not always obvious when a filling needs replacing. That’s why regular dental visits are so helpful; your dentist can spot problems before you feel them. But there are a few signs you can watch for at home.
Pay attention to any new or unusual feelings in your mouth. Your body often gives you clues when something needs attention. If you notice any of these, it’s a good idea to schedule a visit:
- Tooth pain or aches: A new toothache or a dull, persistent ache around a filled tooth could be a sign of a problem
- Sensitivity: If your tooth suddenly becomes sensitive to hot, cold, or sweet things, the seal on your filling may be compromised
- Visible damage: You might see a crack in the filling or a piece that has chipped off
- A change in your bite: It’s a good idea to have it checked if chewing feels different or uncomfortable
How to Make Your Fillings Last Longer
You play a substantial role in the longevity of your dental work. With a few simple habits, you can help extend the life of your fillings. These same habits help keep your whole mouth healthy.
Brush & Floss Daily
Good at-home care is your first line of defence against problems. Remember to brush for 2 minutes, 2 times a day. Daily flossing is also key to cleaning between teeth, where decay around fillings can start.
Eat a Tooth-Friendly Diet
Try to limit foods that can cause damage, such as hard candies, ice, and sticky snacks that can pull on a filling. A balanced diet low in sugar also helps prevent new cavities from forming.
Schedule Regular Checkups
Visiting your dentist for regular cleanings and exams is one of the most effective ways to protect your fillings. Your dental team can identify and address minor issues before they become bigger problems. These visits allow a professional to check on your fillings and overall oral health.
