A dental cleaning is a professional tooth cleaning you receive from a dental hygienist.
Cleanings should be performed at least every six months to prevent excessive plaque buildup. Depending on your periodontal condition and susceptibility, your doctor may recommend a more frequent cleaning schedule. Plaque consists of masses of bacteria that grow between and on teeth, at and below the gum line. Plaque left untreated can lead to unhealthy gums and tooth decay.
