Be specific,how much is your mouth opening? You might need surgical treatment depending upon your mouth opening

It's unfortunate to read this from a 25 yrs old . Well now that you've landed with a problem get yourself examined for oral sub mucous fibrosis and get your medicinal therapy started

Your symptoms are suggestive of a condition called as Oral Submucous Fibrosis. It is mainly due to smoke less tobacco usage, but can also be due to smoking as well as excessive use of Chillies. You need to take care of these habits. 6 months is a short duration to evaluate the reversal of the damaging effects of tobacco which has happened in so many years. Proper evaluation by an oral pathologist can help us in the grading of the lesion, and the right treatment options can be suggested after that. Regards

Pls don't panic it can be repaired by taking some precautions pls minimise the habit gradually as u can't quit in few days pls avoid drinking hot tea,avoid drinking alcoholic beverages,avoid eating hot n spicy food avoid eating Simla mirch.

Please get a check up from a dentist to rule out conditions like OSMF( oral sub mucus fibrosis ) whichmay reduce mouth opening. It is important to get a proper diagnosis.
