The Global Burden of Disease Study 2016 estimates that oral diseases affect half of the world's population (3.58 billion), with tooth decay being the most common condition. Severe periodontitis, which causes tooth loss, is the 11th most common disease globally. Tooth loss and decay are among the top 10 causes of disability. Oral cancer is the 3rd most common cancer of all types.

In developing countries like India, these figures present an even more alarming reality. According to a World Health Organization report (2010), in India “over 70% of the population suffers from gum disease, only 50% use a toothbrush, and only 2% visit a dentist”. Lack of awareness, poverty, illiteracy, indifference to the problems, lack of insurance, and irregular visits to dentists may be the reasons for its high prevalence.

Gum disease, like decay, destroys the structures around the teeth, but is painless. If left untreated, tooth loss can have a major negative impact on an individual's quality of life. It can ultimately lead to a number of digestive and nutritional problems. Evidence from published studies suggests that it is a distinct risk factor for heart disease, stroke, lung disease, and cancer. In addition, pyorrhea is described as a potential risk factor for diabetes, arthritis, premature birth, and low birth weight.

The link between oral health and overall health may be direct, indirect or coincidental; but good oral health helps maintain your health and digestion, which is reason enough to make oral health a priority. It is wiser to prevent diseases in the first place than to treat them. Ignoring problems only increases the pain and expense. Breaking bad habits, maintaining oral hygiene and visiting the dentist at least once a year can prove to be very beneficial in the long run.
