Which tooth brushing technique should you use? If you aren't certain, you are in good company.
A study by University College London examined brushing advice from dental associations in nearly a dozen countries. The study also reviewed tooth brushing recommendations from dental textbooks, toothbrush companies and toothpaste companies.
Surprisingly enough, the associations, textbooks, and companies did not offer the same brushing advice. This was true for tooth brushing methods, how often to brush your teeth, and how long to brush your teeth. The lead author of the study, Dr. John Wainwright, said that the wide range of recommendations found is likely due to the lack of strong evidence suggesting that one method is conclusively better than another.
So what should you do?
The most common recommendation for brushing teeth suggested that the toothbrush should be gently moved across the teeth's surface horizontally. The objective of the brushing should be to release any food particles and bacteria that are stuck on the surface of the teeth.
The study was published in the British Dental Journal.
