[|Human|] I am a regular pan masala (read Rajnigandha but not Gutkha) chewer . My teeth(s) have got red patches from back though not in front and have formed a sort of layer at the back side. There is as such no problem like pain etc but i am getting worried now on how to clear the back of teeth and getting rid of those red patches. Brushes normally cant clear out those areas. Can you suggest me some techniques or any equipment which can help me clean out those patches? or visit to a doctor needed?
[|AI|]  Hello! I have gone through your query. Please QUIT any tobacco usage hereafter. These red patches are teeth discoloration due to pan masala. They cannot be removed at home by yourself. Based on the severity of stains you have, you must get 1 or 2 sittings of professional scaling(cleaning) done. You must also check if your oral mucosa is normal or shows any signs like burning, roughness. Also make sure your mouth opening is normal(3-4 finger wide).regards.
