It is probably the most frequent question being asked to a dentist. The frequency with which we should visit our dentist for preventive purposes or to have some cleaning performed is not the same for everyone. Once every six months will usually have a good result. However, the attending physician is the one who will decide when a checking or cleaning etc should be performed, depending on the needs, oral health and the patient’s hygiene. For example, patients with periodontal disease should visit the dentist more often.
