The Impact of Oral Health on Overall Health and Well-being

Oral Health may seem like a tiny part of the puzzle, but it has a huge impact on overall health and well-being. The mouth is the beginning of the digestive tract that extends through the body; it is the entry point for nutrition and oxygen. Thus, poor health of the mouth will impact the rest of the body. The mouth contains about six million bacteria, most of which are harmless and are controlled by the body’s defense mechanisms as long as good oral hygiene is maintained. In case of poor oral hygiene, these bacteria may multiply, spread, and flow into the bloodstream and reach various vital organs. The main indicators of poor oral hygiene include bad breath, cavities, tooth sensitivity, gum diseases like bleeding or swollen gums, discoloured or stained teeth, dry mouth, persistent toothaches, and plaque buildup. 

If Oral health is not maintained, it may lead to several other health disorders. Poor oral health, especially Periodontitis (gum infection), can lead to the development and worsening of Type 2 Diabetes Mellitus. The inflammation associated with gum disease can enter the bloodstream and cause systemic inflammation, thereby reducing insulin sensitivity and leading to higher blood glucose levels, i.e, worsening of Diabetes. On the other hand, high blood glucose levels can also cause gum disease. Diabetes and gum disease are interlinked, and treatment of gum disease is associated with a reduction in blood glucose levels, a reduction in HbA1c levels, and better control of Type 2 Diabetes. The systemic inflammation that enters blood stream from the gums can then lead to various systemic diseases like Rheumatoid Arthritis, Alzheimers’ disease, dementia, Digestive and gut issues, and Pregnancy and birth complications (periodontitis has been linked to premature birth and low birth weight), etc. If the cavities are not treated on time, it may lead to an infection of the gums, and the bacteria from the gums may enter blood stream and reach vital organs. This may lead to Endocarditis ( a serious infection of the endocardium - heart’s inner lining and heart valves), Cardiovascular diseases, Respiratory diseases, and Stroke. Poor Oral health and chronic inflammation could also lead to the development of Mouth Cancer and other Cancers. In addition, having higher levels of bacteria in the mouth, losing more of one's natural teeth, and experiencing gum disease can all increase the risk of Glaucoma. Some conditions can worsen oral health as well, i.e, Sjogren’s syndrome that causes dry mouth, Cancers and HIV AIDS that cause painful mucosal ulcers and lesions (sores) in the mouth, Alzheimers disease and dementia - as the disease advances, oral health is neglected.

In addition to the above-mentioned systemic diseases, oral health also affects various aspects of life, thereby impacting well-being. Symptoms like bad breath, stained or crooked teeth, gum disease, loss of teeth, etc., can impact one’s confidence and social life. Several individuals with these symptoms become extremely self-conscious, and this impacts their ability to speak in a social setting, smile, or have conversations. This greatly impacts the confidence of individuals and leads to low self-esteem. In some cases, oral diseases can also lead to mental health conditions like depression and anxiety. Oral diseases, pain, and infections significantly influence daily life, making it difficult to eat, speak, and perform daily tasks. Untreated oral diseases can also lead to missing school or work, difficulty concentrating, and a lack of productivity. 

The first step in maintaining good oral health is brushing teeth twice daily and regular flossing. The tongue should be cleaned regularly, and the toothbrush should be replaced every 3 to 4 months. In addition to this, professional dental cleaning should be done once every year. Regular dental checkups are crucial as they help in the early detection of oral diseases, thereby preventing the worsening of diseases and maintaining good oral health. Taking a good, well-balanced diet, limiting sugary foods and beverages can help prevent tooth cavities, decay, and gum disease. Quitting tobacco use in all forms (paan, shisha, bidi, cigarettes, vaping, etc.) helps in maintaining good oral health and prevents gum disease. Extra caution is required if you have the risk factors for poor oral health, i.e, young children or older age, Systemic diseases like Diabetes etc., habits like smoking, alcohol consumption, a diet rich in processed food and sugary food and drinks, etc. Thus, by taking care of oral health with self-care and professional help as required, we can ensure optimal oral health, which leads to optimal overall health and well-being.
