Advice on how we should brush our teeth from dental associations and toothpaste companies worldwide is “unacceptably inconsistent”, according to research done at the University College London and published in August 2014 in the British Dental Journal.
The study looked at the brushing advice given by dental associations across ten countries, toothpaste and toothbrush companies, and in dental textbooks. The team found a wide range of recommendations on what brushing method to use, how often to brush, and for how long.
