Everyone needs their teeth cleaned at least twice a year. No matter how good you do at home brushing and flossing you are probably neglecting some area of your mouth. Once calculus buildup begins there is no way your toothbrush can remove it on its own. I use an ultrasonic scaler which vibrates and sprays water to comfortably and efficiently remove calculus.
