<s>[INST] Iam eating pan parag from 5 years, this has become a habit which iam not able to leave it. This is causing brown coloration of my teeth. I am brushing daily but still ths stain are not going. I am embarassed by this while talking or smiling [/INST] Hi, Thanks for asking the query, As you are feeling embarrassed with the discoloration of your teeth I would suggest you to replace the habit of pan chewing with chewing gums. The stains can be removed with brushing. I would suggest you to visit to the Dentist and get complete mouth scaling and polishing done. At home brush teeth twice daily and use antiseptic mouthwash rinses. If the stains are severe can go for bleaching of the teeth. Hope this helps out, Regards.... </s>
