Hi, I am Dr Sonia S V. I am an ENT Surgeon[Specialist in diseases of the Ear ,Nose ,Throat and Head and Neck Surgery] . Tobacco- Gutka chewing can lead to tightening of the tissues in the mouth and progressive difficulty in mouth opening. This is a condition called oral submucous fibrosis
.Since it is a precancerous condition
it requires a thorough evaluation by an ENT- Head & Neck Surgeon. Tobacco in all forms and alcohol has to be avoided and a periodic examination is required. Medications and treatment for this would depend on the extent of your symptoms and the findings on examination.
All the best
Dr Sonia Suprabha Venugopal
Consultant ENT Surgeon , Head & Neck Specialist,Bangalore
