In my experience a odor like you are describing usually comes from a loose crown. The cement has washed out and the bacteria present is the cause of the odor. I would suggest that the doctor look into trying to remove the crown or redoing it. That is not a pleasant odor to be living with.
have u heard of polident??? its a denture cleanser but can be an effective mouthwash...it can cure bad breath and even removed decay and tartar.....maybe it could help u...hope to hear u soon..
My father just went through the same thing. He is getting ready for a major surgery and the docs needed to make sure he had no infections in his body. He went to the dentist 3 weeks ago because he had a similar bad odor coming from the one side of his mouth. The dentist told him to rinse with a good mouth wash several times a day and try and rinse with peroxide once a day. I got him to use fluorigard mouthwash and peroxide and he said it seemed to do the trick. As the previous poster has said, denture cleaner has been known to really thoroughly cleanse the mouth and kill germs and bad breath. I never personally tried this, but I have been reading up on it and that it has worked well.
Thank you for all your suggestions. I specifically asked my dentist if there could be a small gap which is causing this smell. But he says that the gap between the crown and gum is 3mm which is within acceptable limits.
He said that the top of the root canal dosent look OK. But he said in that case the symtoms would be different.
I have no pain or nothing and the smell comes only from the boundary between crown and gum and does not come from the top part of the gum.
I have tried all mouthwashes but it dosent help.
Anyone please suggest something..Please....
It sounds like that crown needs to be redone. I would get a second opinion.
Regarding the Polident mouthwash thingy, Polident do not produce a mouthwash anymore, and they do not recommend using their denture cleaning products as a mouthwash. Try a chlorine dioxide mouthwash (e. g. OxyFresh, CloSysII, Therabreath, Neways, etc.) instead. They are only available from some dentists, or else via mail order, in the US.
I also have a bad odor from gum just behind a crown and root canal tooth (2nd to last right upper molar). Sometimes it flares up and actually pains and all the dentist recommends is to take antibiotics (Doxycycline or Ampicillin) which actually helps but temporarily. Like your dad I am also due for major surgery in a few weeks (OHS)and am very worried about this infected gum. Does anyone else have some comments on a situation like this? Thanks, ChrisR.
