Visiting a dental hygienist isn't just good for your teeth – it could also protect your heart, researchers claim.
They found that those who have their teeth professionally cleaned and polished at least once a year cut their risk of a heart attack by nearly a quarter.
And they are 13 percent less likely to have a stroke compared to those who have never had the treatment.
Scientists have known for several years that the condition of teeth and gums is strongly linked to the likelihood of heart problems.
Not brushing properly causes plaque to build up, which leads to gum disease. Bacteria then enter the blood stream via the gums, and it is thought that this causes artery walls to become inflamed, which can trigger heart attacks or strokes.
The bacteria may also contribute to the build-up of fatty deposits in the bloodstream, which can also lead to heart problems.
Researchers from Taiwan looked at the records of more than 100,000 adults over seven years and noted how often they went to a dental hygienist.
Lead researcher Emily Chen from the Veterans General Hospital in Taipei, who presented the findings at the American Heart Association's scientific sessions conference in Florida, said: "Protection from heart disease and stroke was more pronounced in participants who got tooth scaling at least once a year."
Natasha Stewart, Senior Cardiac Nurse at the British Heart Foundation, said: "It's already known that poor oral hygiene may be associated with more well known risk factors for heart disease, such as smoking and poor diet."
"So it's important to make sure that good personal hygiene forms a basic part of a healthy lifestyle."
"Keeping your teeth clean and visiting the dentist is important but if you really want to help look after your heart, make sure you eat a balanced diet, avoid smoking and take part in regular physical activity."
