Hai doctor,
i'm Bharath, i'm using chaini khaini for about 7 years. i enjoyed using this at the early stage, but now i'm feeling worried about the defects of using this, perhaps due some changes which is noticed in my mouth recently i.e., darkening in the teeth & gum and also i'm getting pain sometimes. kindly analysis my symptoms and inform me the problem as well as advise me how to get rid of consuming khaini. your kind cooperation will be higly valued.
