Can anyone tell me about possible treatment options of oral submucous fibrosis?

Not a surgery: Oral submucous fibrosis is a chronic, progressive, scarring disease. At a retrospective studies surgery seems to be a poor option in the overall management of the disease. Physiotherapy, nutrition and combined therapy is the better choice.

Complex issue: This may require a mufti-disciplinary approach in a university setting. For an overview of causes and possible treatments look here: http://en.wikipedia.org/wiki/Oral_submucous_fibrosis but this is general information that may not all apply to you. Get to such a facility and get evaluated by the oral medicine department in a dental school and expect consultations with other specialties.
