The word prophylaxis means “to prevent disease”. Therefore, prophylaxis dental cleanings are used to clean healthy teeth in order to prevent them from becoming affected by tooth decay or gum disease. Prophylaxis cleanings remove plaque and tartar from the front, back, and sides of teeth using a dental scaler or water stream. Most dental patients only require a prophylaxis cleaning, especially if they have kept up on daily dental hygiene and semi annual dental appointments.
