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
Brianne,

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.

My tooth is still infected after an apicoectomy. I had a raging toothache and infection that required a same-day visit in early October. The dentist did an apicoectomy on a tooth that had a root canal 2 years ago. I had a checkup and x-ray two days ago. The bone is rebuilding, but a small pus sac on my gums shows an infection is lingering. My dentist gave me antibiotics to take for ten days. Is there anything else I can do to get rid of this infection? I
What’s next if I had a root canal fail? A toothache that has been bothering me for the past two months got so bad last weekend that I saw a nearby dentist for a same-day appointment. I did not want to return to my previous dentist because I didn’t like the customer service at the practice, and the hygienist is quirky. The toothache was in an upper left first molar tooth that my dentist did a root canal on two years ago. The dentist I saw most recently said she would need to refer me to an endodontist for a procedure called an apico? I have been a little slack about going to the dentist, and I haven’t seen one since I quit my last dentist, so maybe I could have avoided this. What is this apico procedure, and do I really need it? Thanks. Malachi
My tooth split in half below the gumline, and I am holding it together with floss. It split last night, and I am calling offices for a same-day crown. I’ve been asking dentists how soon I can get a crown, but the first available appointment is at the end of next week. How long will the tooth hold? It’s beginning to feel loose. – Thank you. Andrej
My cheek swelling increased after wisdom teeth extraction from a sinus perforation. I called the oral surgeon when a yellow discharge started coming from my nose and sockets. The surgeon prescribed Augmentin, which decreased the welling. After two weeks, one sinus was still infected. The surgeon took a CT scan and said my sinus was clear of any fragments that could cause infection. He prescribed Azithromycin, and I have a few pills left. The sinus hole is still draining, and I feel some pressure in it. I use a prescription rinse and Flonase. Are my symptoms typical, or do I need to see a sinus specialist or make an emergency appointment with my dentist? Thank you. Naaman from Brooklyn
Is getting wisdom out urgent? have all four wisdom teeth, and three are impacted. They hurt on and off, so my dentist referred me to an oral surgeon. The surgeon says I should have all four teeth extracted to prevent future problems and another surgery. There is a low risk of never damage from the impacted teeth. My dentist and surgeon are really pushing for surgery. But as I mentioned, the teeth hurt on and off, but the pain is not severe. Sometimes I feel a little pressure, too. I am 29 years old, and if I do not need surgery now, I would be happy to wait. – Thanks. Taylor
Both my bottom wisdom teeth have been hurting on and off for the past year. Last month, the pain increased, and three weeks ago, it was not intense and throbbing that I was nauseous. I do not have a regular dentist, so I found one online that takes emergency patients 24/7. The dentist examined my teeth, took an x-ray, and said both teeth were infected and needed to come out.
