Firstly, if you were allergic to crown material the tissue in the area would be inflammed and the dentist would see that. If he has made no mention of that then it doesn't sound like an allergic reaction. If the bite is correct then the cementation is not the cause.If the gum is bleeding around the crown then you would have to consider the contour or fit of the crown maybe the problem. At this point I can not give you a definitive diagnosis.The good news is the teeth are not sensitive to percussion which tends to indicate that there is a problem with the root canal or any of the adjacent teeth.
Also could there be a gum tear or infection under the crown?
Thanks!
you should get an opinion from someone other than the person who made it. get a referral to another dentist from a family member or friend, not your current dentist. this should not be a great mystery. indeed it sounds to me like the crown may be impinging on the gum tissue becasue the margins are too deep under the gums, or the contour of the crown by the gum tissue is bad.
Thanks for your input. I just feel like my gums are being pressed down upon around the gum line and it feels like my gums are being cut into. Jagged.
