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
