According to data compiled by researchers in Taiwan, people who had their teeth professionally scraped and cleaned had a 24 percent lower risk of heart attack and 13 percent lower risk of stroke compared to those who never had a dental cleaning.

Researchers said a higher frequency of professional tooth cleaning led to a greater reduction in heart risk. They defined higher frequency as at least two visits to the dentist for a cleaning in two years.
