The British Medical Journal reported on a study of??toothbrushing and found that people with poor oral hygiene had an increased risk of cardiovascular disease and heart attack.
We’ve known for the last two decades that inflammation plays an important role in atherosclerosis.??Markers of low-grade inflammation like C-reactive protein are also shown to be higher in heart disease.
The Scottish Health researchers looked at the general population and followed a large subset with questions about their oral health.??They asked about frequency of dentist visits, toothbrushing, and controlled for many co-variables such as general activity, hypertension, smoking, height and weight.??They also collected blood for studies of??C-reactive protein as a marker of inflammation.??They removed from the analysis participants who had no natural teeth (edentulous) and??those with existing cardiovascular disease.
This elaborate and lengthy study showed that toothbrushing is associated with cardiovascular disease, and that subjects who brushed their teeth less than once a day had a 70 percent??increase in heart disease compared with people who brushed twice a day. The inflammation that periodontal disease causes is directly related to increased C-reactive protein and increased heart attacks.
Leave it to the Scotts and the Brits to remind us to brush and floss every day.
