<s>[INST] Dr. i am parasuram, but i am suffering the problem of mouth opening due to chewing of gutaka (tobacco) so many long years.Now how to open my mouth . actually it has to open for four fingers if we keep the finger in the mouth.Now it is opening only 1 1/2 only.Advise [/INST] Thanks for your query, I have gone through your query.The limited mouth opening is because of the oral sub mucous fibrosis. The treatment for this can be started once you stop the habit of gutkha vchewing. Initially you can take antioxidants like multivitamins for 1 month. Later, intra l;esional injections with dexamethasone and hyaluronidase can be administered biweekly for 6-8weeks. Consult a oral physician and get it treated.I hope my answer will help you, take care. </s>
