Dental hygiene is the practice of maintaining one's oral health to prevent dental problems, such as tooth decay and gum disease. A proper oral hygiene routine includes regular brushing, flossing, and visiting a dentist for checkups and cleanings. Recent research has shown a link between poor dental hygiene and an increased risk of heart disease. The link between oral health and heart disease is not fully understood, but it is believed that the bacteria responsible for gum disease can enter the bloodstream and contribute to the development of heart disease. Additionally, people with poor oral health may have a higher risk of developing other health conditions, such as diabetes, which can also increase the risk of heart disease. One of the best ways to maintain good oral hygiene and reduce the risk of heart disease is by brushing and flossing regularly. Brushing should be done at least twice a day, with a fluoride toothpaste, and flossing should be done at least once a day. Additionally, using an antiseptic mouthwash can help to kill bacteria and freshen breath. Visiting a dentist for regular checkups and cleanings is also important for maintaining good oral hygiene and reducing the risk of heart disease. Dentists can detect and treat problems early on, before they become more severe, and can also provide professional teeth cleanings to remove plaque and tartar buildup. It is also important for individuals to maintain a healthy diet and lifestyle to support oral health and reduce the risk of heart disease. This includes eating a diet low in sugar and processed foods, and high in fruits and vegetables, as well as getting regular exercise. Avoiding smoking and excessive alcohol consumption can also help to reduce the risk of heart disease. In conclusion, maintaining good dental hygiene through regular brushing, flossing, and visiting a dentist for checkups and cleanings can help to reduce the risk of heart disease. It's important to take care of your oral health and make sure that you're doing everything you can to keep your heart healthy as well. Dr. A. Arrazaghi. MD,FRCPC
