Dental prophylaxis treatment is a form of teeth cleaning program done by dentists to arrest the progression of periodontal disease and gingivitis. Periodontal disease and gingivitis usually occur when the bacterial plaque accumulates on the gum tissue either above the gum line or below it, thus causing serious inflammation and irritation. Such inflammation starts destroying your gum and bone tissues, thus making your teeth unstable and eventually making them fall out. Prophylaxis in dentistry involves teeth cleaning and removing the tartar from your gum tissues, and is an excellent way of maintaining a good oral health. This form of treatment can be performed either in the course of a regular dental visit or under general anaesthesia. Dentists prefer to perform it under local anaesthesia in case of severe periodontal disease. In such cases, an endotracheal tube is placed in the throat to protect your lungs from being affected by any kind of harmful bacteria that is removed from the mouth. Prophylaxis treatment is usually performed in several stages viz. supragingival cleaning, subgingival cleaning, root planning, medication and finally x-rays and examinations. Although dental prophylaxis treatment can be done twice a year, but patients suffering from severe periodontitis are recommended to undergo the treatment at an interval of every 3 or 4 months. While it's not possible to reverse gum disease completely, but with the help of prophylaxis treatment dentists can at least make the effort of retarding the destructive progress.
