How having your teeth scaled can reduce your chance of having a stoke.
Research recently published in the International Journal of Cardiology showed that patients who had a scale and polish at least once a year were a third less likely to develop an abnormal heartbeat. An irregular heartbeat is a major stroke risk factor.
The more frequently they had a scale the bigger the benefits. It is thought bacteria increases the rate at which arteries get blocked.
