Dental Cleaning


Share it Please

A tooth cleaning is part of oral hygiene and involves removing plaque (soft, sticky, bacteria infested film) with the intention of preventing cavities (dental caries), tartar (calculus) deposits, gingivitis and periodontal disease that have built up on the teeth over time. Teeth are continually bathed in saliva which contains calcium and other substances which help protect the teeth but routinely we should clean our own teeth by brushing and interdental cleaning. This is a good thing that we tend to get a build-up of calcium deposits on the teeth, like limescale in a pipe or kettle. Dental hygienist can remove hardened deposits (tartar) not removed by routine cleaning. If the tartar (calculus) is allowed to accumulate on the teeth it will provide the right condition for bacteria to prosper next to the gums. Cleaning and polishing can clean and smooth the surface of the teeth, and bacteria can’t stick to them. Nowadays, electric toothbrush are developed and come into widespread general use, whereas just recommended for people with strength or dexterity problems in their hands. Electric tooth brushes reduce plaque formation and gingivitis better then manual tooth brush. In some cases, the dental hygienist or dentist gently removes deposits without harming the teeth by specialized instruments. For example an ultrasonic instrument uses tickling vibrations to knock larger pieces of tartar loose, and also sprays a cooling mist of water while it makes to wash away debris and keep the area at a proper temperature. At all, dental cleaning leaves our teeth feeling lovely and smooth and clean, which is so nice when we run our tongue around them.
