Your nasal odor is present all the time? I usually have the nasal odor after I eat. what other symptoms do you have other than odor from the nose?

I have the same problem. I can be in a room and not speak and people still smell the odor from me. I also can only smell it through my nose not my breath. The smell can travel pretty far.

I recently did have an unusually long cold during my dental work. The doc said my sinuses were full. The funny thing is that I've never suffered any sinus infections.

Recently I went to a 2nd dentist to clarify the origin of my BB but she said it wasn't the mouth that was causing a problem.

Then today I coughed out tonsil stones. I too am wondering the cause of BB.
