For the past two months, I’ve been bleeding and peeling gums between my center front teeth. The two teeth and the two behind them on either side are crowns. I asked my dentist for a certificate of the alloys, but the assistant gave me a piece of paper that said the crowns were GC LiSi Impress. Is this product causing an infection? If so, I would rather not return to my dentist. I’m afraid to schedule an emergency dentist that I don’t know. This is frustrating. – Brianne from Tampa
If all your crowns are made of the same material, you should react—inflammation or discomfort—near all the crowns, not just the center front one. GC LiSi Press is ceramic — is a high-density lithium disilicate, and we cannot find credible, documented allergies to the material. We are unaware of a dental allergy causing bleeding, but something may be irritating your gums.
Food particles or something else can sometimes get trapped on an overhand behind a dental crown. Floss thoroughly around and behind the crown to remove anything that is trapped. If you feel a ledge beneath your gum tissue while flossing, it is an overhang that your dentist must correct.
Rather than schedule an emergency dental visit, schedule an exam and X-ray. You and the dentist would not accomplish much during an emergency visit anyway. Look for a dentist with advanced cosmetic dentistry training to see if either dental crown is causing bleeding and peeling gums.
