How Long Do Zirconia Crowns Last?

October 18, 2025

Zirconium crowns have a lifespan of 15 years. However, the actual usage period depends on the maintenance of the crowns and the quality of the materials used. In one study, the survival rate of zirconium crowns was found to be 92.9% after 10 years of use. In another study involving 276 patients, the success rate of veneered zirconium crowns after 15 years of use was 71.7%. The common point of these studies is that the most important factor shortening the life of crowns is crown fractures and chipping.

New-generation monolithic zirconia crowns are produced from a single piece of zirconium and are much stronger. There is no 15-year data on these crowns yet, as the material has only been in clinical use for the last 10–12 years. However, 5–10 year clinical results show a success rate of 90–95%.

How long a zirconia crown will last depends on many factors. Some are related to the dentist’s technique, while others depend on the patient’s habits and oral hygiene.

What factors affect the lifespan of zirconia crowns?

There are many factors that affect the lifespan of zirconium crowns. Well-maintained crowns can last for more than 15 years.

1. Material quality

It is very important that zirconium crown and the adhesive used are of high quality. The crown must adhere well to the teeth. This ensures that the crowns do not loosen and are securely fixed, making them resistant to breakage.

2. Type of zirconia crown

Metal and ceramic zirconium crowns are also durable. However, although metal-coated crowns are durable, they are not aesthetically pleasing. Ceramic zirconia is more aesthetic but more fragile. New generation monolithic zirconia crowns are produced from a single block, so they crack or break much less than coated zirconia crowns. A monolithic zirconia crown is preferred especially for teeth in the back region because chewing force is greatest in these areas.

The problem of cracking and breaking in zirconia crowns is encountered more often in the back teeth. This is because the chewing force applied here is greater. For front teeth, ceramic crowns can be used to achieve a better aesthetic result.

3. Occlusion adjustment

Dental crown fitting the tooth perfectly is just as important as other factors. Proper adjustment of the occlusion height ensures that chewing force is distributed evenly. Otherwise, excessive pressure is exerted on some teeth, which can lead to breakage.

4. The effect of oral care

Zirconia crowns are not directly affected. However, if regular dental care is not performed, food debris can accumulate between crown and the natural tooth or implant. Over time, this can lead to problems such as decay, infection, or gum recession.

Therefore, daily dental care checks and regular visits to the dentist are key to long-term implant use.

5. Teeth grinding or clenching (Bruxism)

Bruxism shortens the lifespan of dental crowns by causing them to crack and chip. Patients with this complaint are advised to use a night guard. A night guard prevents zirconia crowns from breaking.

6. The structure supporting the crown (natural tooth or implant)

Zirconia crowns are placed on natural teeth or implants. According to research, the survival rate of crowns on natural teeth is slightly higher. This is because the fibrous structure surrounding the natural tooth dampens chewing forces to some extent. This protects zirconium crowns from high pressure.

Conclusion

Regular maintenance, avoiding very hard foods, and using a night guard if necessary are very important. In addition, the longevity of crown depends on the dentist’s skill and the laboratory’s workmanship. Correct tooth preparation, proper cementation, and good polishing are other factors that determine the life of the crown.
