In caring for the mouth after periodontal surgery procedures entails the maintenance of good dental hygiene. First and foremost, the dental patient must avoid vigorous or overzealous brushing, but make sure to remove plaque and food debris from sticking into the surface of the teeth. Before the periodontal surgery is undertaken, the dental patient must be informed about the possibility of root hypersensitivity. Information with regards on how to cope with the problem should also be given to the patient. Hypersensitivity appears due to the exposure of dentine which is inevitable if calculus and plaque and their products, buried in the root, are to be removed. Over a few weeks, hypersensitivity slowly disappears. Immediate relief from desensitizing agents may not be produced as they have to be used for several days or even weeks to produce results.
