Dental crowns typically last 10 to 15 years. Some last even longer, up to 25 years or more with excellent care. How long a tooth under a crown lasts depends on how well you care for it and which material your crown is made from. Most people get one or two crowns replaced during their lifetime. With good habits and regular checkups, your crown can serve you for many years.
What Exactly Is a Crown?
A crown is a tooth-shaped cap that covers your entire tooth. It’s like putting a protective hat on your tooth. Your dentist places it over a damaged, weak, or discoloured tooth to make it strong and beautiful again.
Crowns are permanent restorations. Once your dentist cements it on, it stays there. You don’t remove it like dentures. It becomes part of your tooth.
Why Do People Get Crowns?
People need crowns for several reasons:
- To protect a tooth after root canal treatment
- To fix a broken or cracked tooth
- To cover a badly decayed tooth
- To strengthen a weak tooth
- To improve the appearance of a discoloured tooth
- To support a dental bridge
When you’re looking for solutions to tooth problems, your dentist might recommend dental crowns in SW Calgary. Each crown is custom-made to fit your tooth perfectly and match your natural teeth.
How Long Can a Tooth Under a Crown Last?
Most crowns last between 10 and 15 years. This is the average that dentists see in their practices. However, this isn’t a guarantee. Some crowns last much shorter. Others last much longer.
What This Means:
- Some crowns need replacement after 5-7 years
- Most crowns serve well for 10-15 years
- Many crowns last 20-25 years
- A few crowns last even longer
Your specific crown lifespan depends on many factors. The material matters. Your habits matter. How well you care for your teeth matters tremendously.
Why Crowns Don’t Last Forever
Crowns are strong but will eventually wear out. The cement that holds your crown can weaken. The crown may also develop cracks or chips. Bacteria can attack the tooth underneath if they get under a crown. If your gum has receded, the edge of your crown may become visible.
None of these problems happen overnight. They develop gradually over years. That’s why regular checkups help catch problems early.
What Affects How Long Your Crown Lasts?
The Material Your Crown Is Made From
The material your crown is made from determines the lifespan of the crown:
| Material | Typical Lifespan | Appearance |
| Porcelain | 10–15 years | Most natural |
| Ceramic | 12–17 years | Very natural |
| Porcelain-fused-metal | 10–15 years | Natural |
| All-metal | 20–25 years | Less natural |
| Composite resin | 5–10 years | Good |
Factors That Determine Crown Lifespan
Metal crowns last the longest because metal is incredibly durable. Porcelain looks more natural but doesn’t last quite as long. When you visit a dental clinic in SW Calgary, your dentist helps you choose the best material for your situation.
- Your Oral Hygiene Habits: People who brush twice daily and floss regularly keep their crowns much longer. People with poor oral hygiene get decay under their crowns faster.
- Your Diet Choices: Eating hard foods, crunchy foods, and chewing ice damages crowns. Sticky foods can pull on crowns too. People who avoid these habits keep their crowns longer.
- Grinding Your Teeth: If you grind your teeth at night, your crowns wear out faster. A night guard protects your crown from grinding damage.
- Smoking and Alcohol: Smoking stains crowns and weakens the cement holding them. Alcohol can damage the cement over time.
- Your Age: Younger people’s crowns sometimes last longer because their teeth are healthier overall. Age itself doesn’t determine crown lifespan.
- Regular Dental Care: People who visit their dentist every 6 months catch problems early. This helps their crowns last longer. A dental clinic near you can monitor your crown and catch issues before they become serious.
Simple Tips for a Long-Lasting Crown
- Brush and Floss: The quality, flavour, and colour of a crown can only be evaluated after it becomes part of the tooth. Brush twice a day and floss once.
- Avoid Hard Foods: Don’t chew on ice, hard candy, nuts, or hard chips.
- Stop Grinding: If you grind your teeth, ask your dentist about a night guard.
- Avoid Sticky Foods: Sticky candy and gum can pull on your crown.
- Keep Your Checkups: Visit your dentist every 6 months so they can check your crown.
- Don’t Use Your Teeth as Tools: Never use your teeth to open packages or tear things.
When Does Your Crown Need Replacement?
It may be time to replace your crown if:
- It shatters or breaks.
- The cement washes away.
- Rotting takes place underneath.
- The gum line moves back.
- The crown becomes dislodged.
- Placement happened 15 to 20 years ago.
Only your dentist can tell you if your crown needs replacement. Don’t ignore changes or discomfort.
