A dental crown is a custom cap placed over a damaged tooth. Dentists fit crowns to restore a tooth’s shape, strength, and function. They also protect teeth after root canal treatment or large fillings.
Crowns offer strong support. They still wear down over time. Their lifespan depends on the material choice and how well you care for them.
Average Lifespan
How long does a crown last? Most crowns last around 15-20 years. With excellent care, many last 20 years or more. Gum disease or poor oral hygiene can shorten their life.
Factors That Affect Crown Life
Tooth Position
Teeth at the back handle most of the chewing force. Crowns on molars often wear out faster. They may crack under high pressure. Front teeth face other risks. A fall or a sports injury can damage them.
Oral Hygiene
Good hygiene helps crowns last longer. Plaque and tartar build-up can cause decay under the crown. Brushing too hard can wear the crown’s surface.
To protect your crown:
- Brush twice a day with a soft-bristled brush and fluoride toothpaste
- Floss every day or use a water flosser
- Rinse with mouthwash to cut down bacteria
Habits and Lifestyle
Some habits shorten a crown’s life. Teeth grinding, smoking, and nail-biting add stress to crowns. Contact sports without a mouth guard can cause damage. A night guard or sports guard offers extra protection.
Signs You Need a New Dental Crown
Receding Gums
Gums that pull back expose the edge of the crown. This can lead to decay and a visible metal rim on PFM crowns.
Pain or Swelling
Pain around the crowned tooth may mean decay under the crown. A loose crown can irritate gums and cause swelling.
Discolouration
Plaque, tartar, and dark foods can all stain crowns. If your crown looks darker than your other teeth, it may need replacing. Contact us to get more information about dental crowns.
