What is a professional dental cleaning?

A professional dental cleaning, also known as dental prophylaxis, is a preventive procedure in which the dentist or dental hygienist removes plaque and tartar (calculus) that accumulates on the teeth and below the gumline. Unlike daily brushing, a professional cleaning reaches hard-to-access areas and removes calcified deposits that cannot be dislodged at home. The procedure typically has two phases: scaling, which removes tartar using ultrasonic instruments or hand scalers, and polishing, which removes surface stains and smooths enamel to make it harder for plaque to adhere. Some practices also include subgingival irrigation or a fluoride application. The appointment usually takes 45 to 60 minutes. Professional cleaning is recommended every six months for patients with healthy gums; those with a history of periodontal disease may need visits every 3 to 4 months. Patients with active periodontitis — deep pockets and bone loss — typically require scaling and root planing, a more intensive procedure, before returning to a standard maintenance schedule.
