Can a worn crown be repaired?

Question

I had a crown replaced 2 years ago due to grinding. I have a porcelain crown now without any metal. I can tell it’s getting worn again, but it hasn’t grinded down to a hole yet. It’s thin on top of the molar, in the groove. Is it possible to repair it? It has not cracked or chipped. Thank you

Yes, a worn porcelain crown can sometimes be repaired, depending on the extent of the wear. If the crown is simply thinning but hasn't chipped or cracked, your dentist may use a composite resin material to reinforce the worn area. This can act as a temporary fix to prevent further wear.
However, if the wear is significant or the structure of the crown is compromised, replacing the crown is often the best long-term solution. Since grinding is the cause, you may also want to consider a night guard to protect the crown and your natural teeth from further damage. It’s great that you’re addressing this early&mdash;be sure to consult your dentist for the best option!

If your crown hasn't been severely damaged, it can be repaired or replaced. However, you should consult with your dentist to investigate the causes of the issue.

Yes, it is possible to repair a porcelain crown that is thinning due to wear, as long as it hasn't cracked, chipped, or suffered structural damage. The options for repair depend on the severity of the wear and your dentist's evaluation. Here are some potential solutions:
Composite Resin Repair: For minor wear, your dentist may use a tooth-colored composite resin to build up and reinforce the worn area. This is a quick and minimally invasive procedure but might not last as long as other solutions.
Repolishing: If the wear is minimal, your dentist might be able to smooth and polish the surface to extend the life of the crown.
Crown Replacement: If the wear is significant and the crown has become too thin to function properly, replacing the crown may be the best option to ensure durability and protection for the tooth underneath.
Night Guard: Since grinding (bruxism) caused the initial wear, wearing a custom night guard can help protect the repaired or replaced crown and prevent further damage.
You should visit your dentist as soon as possible for an evaluation. They can assess the extent of the wear and recommend the most appropriate treatment. Addressing the issue early can prevent more extensive damage and ensure the longevity of your dental work.
