I'd really appreciate any advice on this. I've never had a problem at all with bad breath but I had a tooth extracted 6 weeks ago and since a couple of days after the extraction, my breath has been awful. The tooth wasn't infected and I had no abscess or anything. It's healed up great but I still have this awful smell.

I thought it would stop within a few days but it's still as bad. I went to my dentist for a check up after 2 weeks and he said it had healed very nicely, though I didn't mention this breath problem as I assumed it would stop. I can't think of anything that would be causing it as nothing has changed diet wise, and I have no sinus pain or signs of infection. I brush twice a day and floss daily, as I've always done. I also use Tepe brushes regularly. I've tried using chlorhexidine but it only masked the smell for about 30 mins.

Could anyone help?
