Hi, About 5 months back I noted there is a white fibrous band or lesion (don’t know correctly) seen on my mouth specifically at pterygomandibular raha areas bilaterally. I can open my mouth but when I do that I feels like some thickness and dryness over that area. I can completely open my mouth, there is no trismus. I consulted a dentist and now taking SM Fibro. What I really have? Do I have Oral sub mucous fibrosis? Is there any serious issue? I don’t have any bad oral habits such as are nut chewing or smoking like that. I’m really afraid of this.
