Brushing your teeth several times a day protects against cardiovascular disease, according to a 12-year study in Scotland.

 

The study found that after 12 years, 3.5 per cent of the group of participants who brushed their teeth less than twice a day had died as a result of heart problems.

Of the group of participants who cleaned their teeth at least twice a day, only one per cent died.

 

There are two possible explanations for the results of this study:

 

1. the lack of oral hygiene causes periodontal disease and other inflammations that promote the calcification of the arteries.

 

2. those who pay close attention to their oral hygiene and brush their teeth at least twice a day are likely to lead a healthier lifestyle overall.
