We're advised strongly from the time our first teeth arrive: brush and floss at least twice a day to maintain good oral health. But new research has uncovered another compelling reason to practice proper oral hygiene-it may play a role in supporting the health of your cardiovascular system.

A recent study analyzed information collected over several years from more than 11,000 individuals who participated in the Scottish Health Survey¹. According to the initial data, 62 percent of participants visited the dentist every six months, and 71 percent reported brushing their teeth at least twice per day.

After adjusting the results of follow-up data for common risk factors such as smoking, obesity and family history, researchers concluded that those who admitted to brushing their teeth less than twice per day had a 70 percent increased risk of cardiovascular disease. The study also found that individuals who brushed less often had a higher blood concentration of certain compounds associated with low grade systemic inflammation, a factor which may contribute to poor cardiovascular health.

Another study analyzed the oral hygiene habits and cardiovascular health of more than 54,000 Japanese men and women². Researchers found that lower frequency of teeth brushing was related to a higher occurrence of several major cardiovascular risk factors, including diabetes, hypertension, high triglyceride levels and low levels of good (HDL) cholesterol.

While the link between oral and cardiovascular health may seem surprising at first, it's important to remember that your body's systems are closely connected and can affect each other in many ways. Establishing a proper oral health routine is an important part of supporting overall health.

The best way to maintain the health of your teeth and gums is to brush at least twice a day, or after every meal when possible. Use a soft-bristled brush, making sure to tackle every surface of the mouth, including teeth, gum lines, cheeks and tongue.  Natural toothpaste made with tea tree oil may be helpful, as this essential oil has germ-fighting properties.

Remember to follow up with floss to remove food particles that may be trapped between your teeth in hard-to-reach places. Additionally, alcohol-free mouthwash made with essential oils such as tea tree and peppermint can help cut down on bacteria without drying out your mouth, leaving behind clean, healthy teeth and gums.

As always, to your good health,
