How Long Does a Dental Crown Last?

If you have a large cavity or fracture in your tooth, a dentist’s first mission is to attempt to save the tooth. We do this in many cases with a root canal or other procedures that could, while saving the tooth, affect its structural integrity. 

To completely restore the tooth’s structure and function, we then place a dental crown over it. 

Crowns can also anchor a dental bridge or to cover shapeless or severely discolored teeth. While there are alternative treatments to crowns in some cases, such as fillings or onlays for minor damage, a crown is often the best choice when a tooth is severely damaged. 

According to one 2022 study, some dental crowns have a success rate of up to 85% even after 25 years of use. The lifespan of your dental crown depends on what material it’s made from, your lifestyle habits, and your dentist’s expertise.

With years of experience and a commitment to using only the highest quality materials, Robert F. Wilcox, DMD, is the go-to specialist for long-lasting dental crowns in Butte, Montana. Here, he explores the factors that contribute to the lifespan of crowns and what you can do to extend them.

How long do dental crowns last?

Several factors determine how long your crown can last. Those to keep an eye out for include:

The material of the crown 

Crowns are made from metal alloys, porcelain fused to metal, all-ceramic, or all-resin materials. On average, with proper care, metal alloy crowns last the longest, often 20 years or more. Porcelain fused to metal (PFM) crowns last an average of 15-20 years, as the porcelain can chip or wear down over time.

On average, all ceramic crowns such as zirconia or lithium disilicate last 10-15 years. But they may be more prone to fracture than metal crowns, especially in patients who grind their teeth. 

All-resin crowns are the most affordable but last only 5-8 years before needing replacement.

Oral hygiene and care 

Regularly brushing, flossing, and getting dental cleanings help your crown last as long as possible. Crowns can still get cavities around the edge without proper hygiene. Brush twice daily with fluoride toothpaste and floss regularly to keep your gums healthy.

Use an antibacterial mouthwash for added protection. Routine dental checkups and cleanings also allow Dr. Wilcox to monitor the health of your crown and address any issues early. 

Lifestyle habits 

Grinding or clenching your teeth, biting objects like pens or fingernails, and mouth piercings put excessive stress on a crown and could cause it to fracture prematurely. 

Dr. Wilcox may recommend a night guard if you grind your teeth. Also, limit sugary and acidic foods that can lead to decay around the crown. Opt for a diet rich in fruits, vegetables, and calcium to support your oral health.

One of the most crucial factors in the lifespan of a dental crown is who places it. A crown’s fit and bonding significantly affect its long-term durability and appearance. That’s why choosing a respected dental specialist like Dr. Wilcox is one of the best investments you can make for your oral health.
