Background: We look at individualised periodontics from the standpoint of public health. Whether or not they are patients inside a health-care system, everyone may be healthy by establishing and maintaining the conditions and circumstances necessary for this to happen. One of the most common causes of tooth loss and a disorder with a modest prevalence is periodontitis, for which the idea that everyone is susceptible has long been debunked. Even though plaque must exist, it is unknown which individuals may eventually develop periodontitis. It is not well known how the contributing processes work in this process. Periodontitis is currently thought to be the body's immunological reaction to plaque, which involves a complicated interaction of plaque composition, genetic make-up, general health, lifestyle factors, and social factors. Plaque clearance alone may be sufficient to avoid periodontitis despite its complicated origin and progression. Severe periodontitis is the sixth most prevalent chronic inflammatory illness in the world, yet only many people with periodontitis are unaware that they have it because it rarely hurts. It can cause considerable morbidity and financial hardship if neglected. Periodontitis is a serious and underappreciated public health issue. The study, teaching, and practise of periodontology may be revolutionised through individualised periodontics. Early breakthroughs in diagnostic and prognostic testing using non-invasive samples, such saliva and gingival fluid, are encouraging. These could aid in pinpointing the individuals with gingivitis who will eventually develop periodontitis. Contrarily, people who are most susceptible to periodontitis are also the least able to pay costly clinical treatments. On the one hand, periodontal health can be attained simply by effective daily personal plaque control and quitting smoking. On the other hand, high-cost, cutting-edge scientific developments in periodontics are extremely important and vital
