Dental prophylaxis is also called professional dental cleaning in common man's language. It is one of the most effective forms of preventing dental diseases. Dental prophylaxis can eliminate the need of dental fillings, dental crowns and every other form of teeth restoration simply because when the patient is free from dental plaque there are less chances of tooth decay. The treatment involves examination of teeth and taking early steps to avoid tooth decay. Plaque and irritants are completely removed from the oral cavity during the process. Scaling and root planing and removal by ultrasonic technology are the methods commonly followed for the purpose.
