Am 23. I chewed gutkha and tobacco for five years but not consistently. I developed oral submucous fibrosis. Their are many whitish fibrous bands in my mouth and soft palate. My mouth opening is good and I already met ENT doctor many times and he said nothing to worry about. But the biggest problem is that I develop consistent mouth ulcers even I didn't chew gutkha right now. Doctor told me Whatever damage is done to my mouth will remain permanent but you should quit tobacco and I did the same thing as doctor said. But I'm getting mouth ulcers consistently and Whenever I eat anything it hurts my mouth due to trauma. I'm really scared that one day this fibrosis will turn into cancer due to this frequent ulcers. I'm spending my time thinking about the same thing over and over again even my doctor said nothing to worry. But I'm really scared please help me.
