I had had this problem for approximately two years, with no relief. Additionally, I was prescribed periostat for this problem, and had some work done around the gum line. However, theis problem persists. I am at my wits end. The crown is on the upper right, I believe a canine tooth. If anyone knows anything, your response would be sincerely appreciated. This is very very distressing
Probably not from the cement, especially if you have other crowns with that cement. Usually the odor is from either decay or periodontium. Make sure there is no decay by the post. Are you a smoker?
