If you’ve had a crown placed — or your dentist has recommended one — you may be wondering:
“How long will it last?”
The good news? With the right care, dental crowns can last 10 to 15 years or longer. In many cases, they last well over 20 years.
Of course, several factors affect how long a crown will hold up, from the materials used to your at-home habits. Let’s take a closer look at what impacts crown longevity — and how to make yours last as long as possible.
🦷 What Is a Dental Crown?
A dental crown is a custom-made “cap” that covers and protects a tooth that’s been:
- Damaged by decay or trauma
- Treated with a root canal
- Weakened by a large filling
- Misshaped or discoloured
Crowns restore function, strength, and appearance, and are made from materials such as:
- Porcelain or ceramic (tooth-coloured and natural-looking)
- Zirconia (extremely strong and durable)
- Porcelain-fused-to-metal (PFM)
- Gold or metal alloys (often used for molars)
⏳ How Long Do Crowns Usually Last?
On average:
- Porcelain or ceramic crowns: 10–15 years
- Zirconia crowns: 15–20+ years
- Gold or metal crowns: 20+ years (extremely durable)
- Porcelain-fused-to-metal crowns: 10–15 years
With proper care, it’s common for well-made crowns to last 15–25 years or longer, especially when placed on healthy teeth and maintained properly.
🧼 What Affects How Long a Crown Lasts?
Several key factors impact crown longevity:
- 1. Material Used
Zirconia and gold crowns tend to last longer than porcelain, though all materials have excellent durability when properly maintained. - 2. Location in the Mouth
Crowns on back teeth (molars) take more biting pressure, so they may wear down faster than those on front teeth. - 3. Oral Hygiene Habits
Brushing, flossing, and regular cleanings keep the tooth underneath the crown (and surrounding gums) healthy — reducing the risk of decay or crown failure. - 4. Bite and Jaw Habits
Clenching, grinding (bruxism), or chewing on hard objects (like pens, ice, or fingernails) can cause crowns to crack or wear down sooner. - 5. Gum Health
If your gums recede over time, the edge of the crown may become exposed, increasing the risk of plaque buildup and decay underneath. - 6. Dental Work Over Time
If nearby teeth shift, or if the crown becomes loose or damaged, it may need to be repaired or replaced to maintain a good fit.
🛡️ How to Make Your Crown Last Longer
- Brush twice daily with fluoride toothpaste
- Floss carefully around the crown
- Use a night guard if you grind or clench
- Avoid chewing ice, hard candy, or sticky foods
- Get regular dental check-ups to monitor the crown and surrounding tooth
🔄 When Should a Crown Be Replaced?
You may need to replace your crown if:
- It becomes loose or falls out
- You notice pain, swelling, or decay near the crowned tooth
- The crown is cracked, chipped, or worn
- There’s visible metal showing through
- The fit feels off or causes issues with your bite
If you’re unsure, your dentist can assess the crown with X-rays and a visual exam during your regular visits.
