How Long Do Full Coverage Crowns Last?
The longevity of full coverage crowns will depend on a variety of factors, such as what type of material is used, where the crown is located in the mouth, and how consistent and thorough your oral hygiene practices are. Durability is one of the biggest benefits of full coverage crowns, and if properly taken care of, they can last up to fifteen year or longer.
Different Material Types
The type of material used for your full coverage crown will be one of the primary determinants of its durability. The following are the most common types of materials used:
- Porcelain Crowns: Porcelain crowns are frequently used for their aesthetic appeal, especially for front teeth. Porcelain crowns typically last between 5 to 15 years, depending on your level of care and the extent of wear. Although they offer a natural appearance, porcelain is more susceptible to chipping compared to metal crowns.
- Metal Crowns: Gold and other metal crowns are sometimes preferred for their strength and durability, as they last on average 10 to 20 years or more. Metal crowns are often recommended for back teeth. The biggest drawback to this option is the aesthetic impact on your smile.
- Porcelain-Fused-to-Metal (PFM) Crowns: PFM crowns combine the strength of metal with the aesthetics of porcelain and typically last between 10 to 15 years. While this option does provide a great deal of stability, there is risk of developing gum irritation from the underlying metal. The metal can also become visible at the gum line if you experience gum loss, which is a common result of periodontal disease.
- Zirconia Crowns: Known for their superior strength and natural tooth-like appearance, zirconia crowns can last 10 to 15 years or longer. They are also less prone to chipping and are frequently used for anterior and posterior restorations.
The lifespan of a full coverage crown will be determined by the following factors:
- Bruxism/Teeth Grinding: Teeth grinding or bruxism will significantly shorten the lifespan of crowns. If you clench or grind your teeth, talk with your periodontist about steps you may be able to take (such as wearing a nightguard) to reduce wear and tear to your full coverage crowns.
- Location in the Mouth: Crowns placed on back teeth are more prone to damage as they will bear more of the brunt of chewing forces. Given this additional wear, a stronger material may be necessary to ensure durability.
- Oral Hygiene: Maintaining excellent oral hygiene is crucial for ensuring your crowns last a long time. Healthy will support the crown firmly and prevent decay at the base, and conversely, neglecting dental hygiene can result in gum disease, which can compromise the integrity of your full coverage crown.
To prolong the lifespan of your full coverage crowns, be sure to maintain good oral hygiene habits, like regular brushing (twice daily) and flossing. It is also important to be mindful of your diet and to drink plenty of water. Finally, regular visits to the dentist for check-ups and cleanings are essential for identifying potential issues with the crown or surrounding teeth and maintaining your oral health.
