Dental crowns, or porcelain dental crowns, are a type of dental restoration that is used to cover or ‘cap’ teeth when they are severely damaged or decayed, as well as to provide cosmetic enhancement. A crown replaces a tooth’s outer surface to provide strength, enhance appearance, and improve alignment. Dental crowns are also placed on top of implants, thus replacing the missing natural tooth.

How long does a crown last?
How long a dental crown lasts depends on several factors, such as type of crown, proper maintenance, and exposure to wear. Proper dental hygiene is just as important in maintaining a crown as it is your natural teeth. If crowns are not properly cleaned, plaque and tartar can deposit around the margins and lead to decay.
People who clench and grind their teeth typically show excessive wear, cracks, and sometimes broken teeth. The same thing can happen to a dental crown which usually results in the crown being fracture and/or the seal becoming compromised, resulting in the need for crown replacement.
For patients that do clench and grind, a night guard would be recommended to protect all teeth and restorations.
