Pigmentation on the teeth is usually not effectively removed by daily brushing and can only be removed by basic periodontal treatment. In this case, ultrasonic scaling, or full mouth scaling, is needed. Through effective full mouth scaling, plaque, calculus, food debris and pigmentation attached to the tooth surface can be removed, and through polishing and varnishing, the teeth will be as white and beautiful as ever. However, if you do not change your eating habits and continue to drink foods and beverages such as strong tea and coffee after a full mouth cleaning, you may continue to cause pigmentation on your teeth.
