When Should You Replace Your Dental Crown?
Dental Crowns or "Caps" are often done when there is not enough natural tooth left to allow for normal function without a chance the tooth may crack or fracture. It's very likely if you're reading this, you have at least one crown and think you'll that crown will last forever. Unfortunately, that is not the case. It's like I tell my patients, "We don't last forever, so it's incorrect to think fillings, crowns, or even natural teeth will last forever." If you have a crown and live long enough, it will likely need to be replaced. But how do we know when it's time?
According to studies, a crown, on average, lasts 6-8 years. In my opinion, crowns should last much longer if done well and taken care of. Most patients think when a tooth is crowned, it never has to be done again. Unfortunately, this is not the case. Other than the crown's age, other factors determine when it's time to replace a crown. Obvious signs are cavities at the margin where the tooth and crown meet. Yes, teeth with crowns can still get cavities. So daily flossing, brushing, and watching your diet are still important, even for teeth with crowns.
Gum recession can expose the margin where the tooth and crown meet. When this happens, the natural tooth will begin to wear from under the crown causing a gap between the tooth and the edge of the crown. This allows bacteria to collect at the margin, forming cavities at the edge and under the crown. When a recession occurs, it's essential to monitor the crown margin and replace the crown at the first sign of any open margin.
Crowns are typically made from porcelain, which can fracture and break over time. When this occurs, it's time to replace that crown. Regular dental checkups can identify any of these issues early and avoid more significant problems down the road.
