Periodontitis is a chronic disease, and as is true for other chronic conditions, it requires constant monitoring throughout life following active treatment. Depending on the used treatment (gingivitis, mild, moderate or severe periodontitis), patient’s oral hygiene practices, percentage of bleeding, number of teeth that have gum pockets >4 mm, smoking and general health condition, an individual re-call schedule will be established after the end of active treatment. During the first year following treatment, the patient has to visit the dentist more frequently.
The patient should go to a check-up and teeth cleaning every 3–4 months. Later, the frequency of re-call depends on the above mentioned factors. Preserving treatment is important for patients that undergo a corrective treatment phase as well as for those that have only non-surgical treatment. As the patients that have suffered from periodontitis belong to a risk group with a higher likelihood of reoccurrence of the disease, it is very important to regularly keep track of the condition of the gums.
Studies show that in case of application of a regular re-call system very few patients and small amount of teeth surface experience reoccurrence or progression of the disease. Loss of teeth during this period was <2% and most of the teeth were removed in relation to some other diagnosis (e.g. broken roots). The study also showed that dental caries occurred much less frequently during this 30-year period (on an average 1–2 new cases per a person, of which most were related to old fillings). A thorough check-up is important for the preservation of healthy gums and teeth
