Those who brush their teeth three times a day or more have a lower risk of diabetes, according to a new study.
Frequent brushing can lower the chances of developing diabetes by 8%.
Additionally, the presence of dental disease is linked with a 9% risk increase – and this stands at 21% for those missing 15 teeth or more.
Results were different for adults 51 and under and adults 52 and older, however.
When compared to those who brushed their teeth once a day or not at all, the younger group had a 10% reduced risk of developing diabetes by brushing twice a day.
This increased to 14% when brushing three times a day.
In the older group, there was no difference in risk between those brushing twice and those brushing once or not at all.
On the other hand, brushing three times a day links with a 7% drop in risk.
The study analysed data collected by the National Health Insurance System-Health Screening Cohort (NHIS-HEALS) in Korea between 2003 and 2006.
It looked at more than 188,000 subjects.
The research was carried out by Dr Tae-Jin Song of Seoul Hospital and Ewha Woman’s University College of Medicine, alongside other authors.
