I got four new crowns in 2020. I fell at work two weeks ago, and two crowns chipped. Now the metal is showing through. My dentist said she needs to replace the crowns because she can’t repair them. I got a second opinion from another dentist who said the same. Is replacing the crowns my only option? Thanks. Aaron from Chicago
Aaron,
The dentists you spoke with may have suggested replacing your crowns because they may not have the specialized skills to repair them with composite bonding, especially when hiding the metal underneath. Understandably, emergency appointments don’t always allow for extensive dental work.
A skilled cosmetic dentist, however, can restore your crowns using a more advanced technique:
- Etching the Metal: A small sandblaster creates a rough surface on the metal, which helps the bonding agent adhere.
- Etching the Porcelain: The broken edges of the porcelain are etched using either a sandblaster or hydrofluoric acid to improve the bond with the composite material.
- Applying a Bonding Agent: A silane coupling agent creates a strong bond between the porcelain and the composite.
- Adding an Opaquer: An opaquer is applied to the metal to mask its appearance and allow the composite to blend seamlessly with the porcelain.
- Bonding the Composite: A shade-matched composite material is bonded to the crowns, restoring their original appearance.
Cosmetic dentists prioritize the aesthetic outcome of dental treatments. That’s why they typically avoid using metal-based crowns on visible teeth. If your current dentist placed these crowns, they may not have the expertise to achieve a natural-looking result with ceramic restorations.
While a skilled cosmetic dentist can restore your crowns, remember that all dental restorations will eventually age. When it’s time for new crowns, consider all-ceramic options for a more natural and long-lasting result.
To find a qualified cosmetic dentist, look for professionals who have completed advanced training in cosmetic dentistry. Schedule consultations with two or three dentists to discuss your options and get a second opinion.
