While most dentists and dental associations agree on the importance of brushing your teeth twice a day, there is no clear consensus on how to brush your teeth. teeth.
Alarmed by this observation, a team from the University College of London decided to take stock of the various recommendations, in order to establish the prototype of effective brushing.
The researchers thus reviewed the recommendations of 10 different countries, given by dental associations, dentists, dental textbooks and toothpaste manufacturers. They then found great disparities concerning the recommended brushing time and the brushing method.
“The public needs clear information on the best way to brush their teeth, explains Aubrey Sheiham, professor of dental public health and co-author of the study, if people hear one thing from a dental association, another from a toothbrush company, and yet another thing from their dentist, no wonder they don’t know how to brush anymore. »
Thus, scientists have found that the recommendations dental associations were not the same as mentioned in dental textbooks. Moreover, it has not been proven that circular “complex brushing” is better than simple brushing.
A gentle brushing would be sufficient
“Gentle brushing with a simple horizontal friction and a brush oriented at 45 degrees helps to remove dental plaque” says Professor Sheiham. “To avoid brushing too hard, hold the brush like a pencil rather than a clenched fist. This simple method is perfectly effective in keeping gums healthy » adds the author.
Similarly, the study reveals that brushing your teeth after eating sweets is useless because it’s actually too late: the bacteria in the food only take two minutes to produce the acid that damages the enamel.
