Dental cleanings involve removing plaque (a soft, sticky layer of bacteria, food & saliva) and hard tartar (calculus) deposits that have built up on the teeth over time. Your teeth are continually bathed in saliva which contains calcium and other substances which help strengthen and protect your teeth. While this is definitely beneficial, it, unfortunately, means that we tend to get a build-up of calcium deposits on the teeth. This chalky substance will build up over time, almost like the limescale deposits at the base of your kettle. For more details please contact us! 8398055117.
