Deep cleaning or what is called scaling and root planning is a procedure done by the hygienist to scrape of tartar build up and infected tissue inside the pocket. This procedure is done when the patient has deep pockets that are 5 mm or more which means that there is periodontal disease present. It can be an active infection or chronic condition when there is bleeding upon probing the pocket depths. Sometimes, placing topical anesthesia in the pockets is needed or even injecting anesthetic in the area of concern so that patients can be more comfortable during the procedure. After the deep cleaning, gingival irrigation with chlorhexidine is done to make sure that there is a decrease in bad bacterial counts and at the same time aid in the healing process of the affected sites. After the procedure, there might be discomfort which may necessitate taking a mild pain killer.
