Teeth cleaning is part of oral hygiene and involves the removal of dental plaque from teeth with the intention of preventing cavities (dental caries), gingivitis, and periodontal disease. People routinely clean their own teeth by brushing and interdental cleaning, and dental hygienists can remove hardened deposits (tartar) not removed by routine cleaning.
Teeth cleaning (also known as prophylaxis, literally a preventive treatment of a disease) is a procedure for the removal of tartar (mineralized plaque) that may develop even with careful brushing and flossing, especially in areas that are difficult to reach in routine tooth brushing. It is often done by a dental hygienist. Professional cleaning includes tooth scaling, tooth polishing and debridement if too much tartar has accumulated. This involves the use of various instruments or devices to loosen and remove deposits from the teeth.
