[|Human|] Dear Sir My teeth are becoming yellowish and also I have several stain mark on them. I used to brush my teeth twice a day, regularly. I used to do profession teeth cleaning once in a year. My friends have white clean teeth. They are as careful as I am. But, My teeth are becoming white some days after profession teeth cleaning. My font teeth are also becoming thinner by days. That I am not sure but I feel. Is it fluorosis? Please suggest how to get rid of the stain problem ?
[|AI|]  Thanks for your query, I have gone through your query. The staining over the teeth can be because of the coffee, tea or smoking(if you are a smoker). But the yellowish color can be because of the deposit(calculus) or it might be because of normal physiological wearing away of teeth structure. Since you are telling teeth will become white after getting your teeth cleaned, it indicates it is because of deposits and stains. Concentrate on the cause what i have mentioned previously, rinse your mouth soon after eating or Chat Doctor.  If the color is bothering you too much then consult an oral physician and plan for veneers. I hope my answer will help you, take care.
