<bot>: Hi, Thanks for asking the query, Tobacco contains carcinogenic materials and chewing of tobacco can eventually lead to gum, periodontal diseases and even cancer. Before jumping to any conclusion, I would suggest you to consult to an oral surgeon get a checkup done, take an OPG radiograph also a biopsy is required. Take a course of multivitamin supplements. Take lukewarm saline and antiseptic mouthwash rinses. Take care!
