Dental crowns are a common solution for various dental problems, ranging from severe decay to cosmetic concerns like a cracked tooth. These versatile restorations cap or encircle a tooth, restoring its original structure and functionality.
They can be crafted from various materials, including porcelain-fused-to-metal (PFM), ceramic, composite resin, zirconia, gold, or metal alloys. Your dentist may recommend a specific material based on the tooth’s location.
For example, a crowned tooth toward the front of your mouth may be made from porcelain, so it blends in naturally with your smile. Whereas a crown on a molar may be made from PFM because it is subjected to more chewing force.
Regardless of the type of material or the reason for the crown, patients often ask their dentist how long their crown will last.
Lifespan of a Dental Crown
Typically, dental crowns last between 5 and 15 years on average, although they can last much longer with proper care and maintenance. The longevity of a dental crown largely depends on several factors, including the type of material used, the skill and precision of the dentist, the patient’s oral hygiene habits, and the wear and tear the crown is exposed to daily.
Material Used
Different crown materials have varying lifespans. For example, amalgam metal crowns are exceptionally durable, often lasting 22.5 years on average due to their high resistance to wear and tear.
Porcelain and ceramic crowns are more aesthetic, mimicking the natural tooth color, but they may not be as long-lasting as their metal counterparts. Metal oxide ceramics like zirconia have a 94% survival rate after ten years, and leucite-reinforced ceramics have a 95% chance of survival after 11 years. Composite resin crowns are less durable and have a survival rate of around 50% after ten years.
Dental Habits and Hygiene
Regular brushing, flossing, and professional cleanings can prolong the life of a dental crown. Neglecting oral hygiene can lead to problems like gum disease and tooth decay, undermining the crown’s foundation and causing the adhesive cement to weaken. Also, teeth grinding or clenching, biting nails, or chewing on hard objects can place excessive stress on the crown, reducing its lifespan.
Placement and Installation
The skill and precision of the dentist during the crown’s placement and the overall health of the underlying tooth can also impact the crown’s longevity. A well-fitted crown reduces the chances of bacterial infiltration and subsequent decay.
Maximizing the Lifespan of a Dental Crown
While some factors affecting a crown’s lifespan are beyond your control, there are several measures you can take to ensure your dental crown lasts as long as possible. Maintaining good oral hygiene is essential; this includes brushing twice a day, flossing daily, and visiting your dentist for regular check-ups and cleanings.
Using a mouthguard during sports or for nighttime teeth grinding can protect your crown from premature damage. Avoid hard or sticky foods that could crack or dislodge the crown, and refrain from using your teeth as tools like opening bottles or packages.
