i brush my teeth twice daily. even then my teeth are yellow. what to do?
even after brushing twice daily if your teeth remain yellow then there are chances of calculus deposits on your teeth. brushing alone does not remove calculi. a painless dental procedure called scaling has to be done immediately. scaling is a must for you at this stage because calculi left untreated will cause gum problems. consult a dentist online to know more about scaling --> <link>
