Teeth cleanings often involve the use of an ultrasonic scaler to remove any plaque, stains and hard calculus build-up on the teeth surfaces. The quick vibration and jet of water that the scaler produces may feel sensitive to some people. But with regular dental cleanings and the use of fluoride or special toothpastes this sensitivity may ease. After the scaling procedure we usually polish the teeth to remove any other stains and provide fluoride treatment. No matter how well you keep your teeth clean, they do also need to be professionally cleaned as toothbrushing alone does not remove calculus. We usually recommend having a dental cleaning every 6 months to maintain healthy gums and teeth.
