Hi Dear,
Welcome to HCM.
Understanding your concern.
Brief answer - Extrinsic stains on teeth.
Detailed answer - As per your query brown stains on lower anterior teeth is because of frequent consumption of coffee, tea, chocolate or drinks which contain caramel. It could be because of excessive
smoking, excessive fluorides in your water or diet, and it could be because of certain trauma due to which tooth become dead and eventually becomes brown/black. Well all these factors and stains caused by them are extrinsic and can be easily treated.
I would suggest you to maintain proper dental hygiene with regular brushing and flossing. Visit
dentist and go for whitening procedure only in front tooth region commonly known as bleaching. Avoid drinking these substances which contain excessive caramel in them. You can go for veneering as well as it will give a coating to your anterior region. Home remedy for this is take a very small amount of
sodium bicarbonate and rub it on stained area for 2-3 min. on daily basis , make sure you don't touch gums otherwise it will cause burning there.
Enamel micro abrasion is another rotatory method which is used to prevent discoloration, you should go for it after proper oral examination.
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
