[|Human|] nasty taste in mouth , hard to explain it,but gross maybe chemical rotten taste? and also smell ammonia everywhere. both after stopping smoking about 5-7 days?
[|AI|]  Hello and welcome to Chat Doctor forum, as stated by you, foul odor from mouth, is associated with a number of factors, smoking is one of them, more than that, poor oral hygiene results in accumulation of calculus which initiates inflammation of gums(gingivitis), followed by periodontitis.according to the history provided by you, it seems to be a case of periodontitis which is responsible for foul smell, until diagnosed clinically by a dentist.I would recommend, stop smoking, get professional cleaning of teeth every 6 months, use antibacterial mouthwash twice daily, and brush your teeth twice daily.I wish you good health.
