Antibiotics Before Treatment. In cases where the individual has a mitral valve prolapse or history of rheumatic heart disease, pretreatment with an appropriate antibiotic is required before any dental work, including cleaning. This is necessary to prevent the possibility of bacterial endocarditis, which can be life threatening.

Deep Cleaning: Scaling and Root Planing

Scaling, polishing, and sometimes curettage are used to manage periodontal disease. They are usually accomplished in a series of three to four visits spaced about a week apart. (Patients might ask their dentist about the gas nitrous oxide, which is helpful for many patients and may reduce the visits to a single one.) The dental hygienist or practitioner generally uses both ultrasonic and manual instruments to remove calculus.

• Calculus above the gum is easily seen. The dental professional usually detects calculus below the gum by careful probing with an instrument.
• The hygienist or dentist may use an ultrasonic instrument for removal of the more accessible calculus. This probe-like device vibrates at a frequency range higher than is audible to the human ear. Some people with low tolerance for the ultrasonic probe may wish to request nitrous oxide.
• A spray of water is used with ultrasound to prevent overheating and to flush out the debris that is dislodged. Povidone-iodine (PVP-I), a potent antiseptic, can reduce the level of gingivitis and may be more beneficial than water as the irrigant used during ultrasonic treatment. Further studies are needed.
• The dental professional will scrape the plaque and from form above and below the gum line (called scaling). When the probe contacts the rock-like calculus, deposits fracture off the tooth fairly efficiently.
• The hygienist or dentist will then smooth the rough spots on the tooth and helps remove bacteria that collect there (root planing) Smooth the surface also helps the gums reattach.
• Polishing is the finishing procedure. It employs a rubber cup with an abrasive paste to remove plaque and stains on the crown portion of the tooth. It produces a smooth surface, making it temporarily harder for plaque to adhere.
