How long does periodontal treatment take? This is a very common question asked by most patients. The treatment process, time and plan for periodontitis are based on the severity of the disease and the time required for treatment varies from patient to patient. For milder cases of periodontitis, treatment usually takes about 2 weeks, and for more severe cases, it takes 1-2 months for basic periodontal treatment, and after 6-8 weeks of basic treatment, the patient will be asked to come in for a follow-up and review. Based on the results of the review, the patient will be re-evaluated and the next course of treatment will be decided. So each patient with periodontitis is actually an individualized treatment plan, and each patient’s approach is different and treatment time varies. In addition, periodontitis is an irreversible disease, patients should pay special attention to long-term oral hygiene, which requires lifelong maintenance, so that the inflammation can be kept under control and prevent the disease from progressing towards a more serious situation, while preventing premature loosening and even loss of teeth.
