2019: Electric toothbrushes retain 20% more teeth

As it became known on August 19, 2019, scientists from the University of Greifswald (Germany) proved that electric toothbrushes better support dental health than ordinary manual brushes. The study, which lasted 11 years with the participation of more than 2,800 German residents, showed that the long-term use of an electric toothbrush slows down the development of periodontal diseases and allows 20% more natural teeth to be preserved compared to the use of conventional manual analogues.

These results support the findings of the Cochrane Collaboration, an independent international organization that has reviewed a number of clinical studies involving more than 4,600 people. The results of the analysis are unambiguous: compared to manual, electric toothbrushes with reciprocating technology more effectively remove plaque and improve gum health both in the short and long term. The efficiency of the technology is due to the fact that the cleaning head moves in three planes, while its small size allows removing up to 100% more plaque even in inaccessible places, experts say.

According to August 2019, in Europe alone, more than 50% of residents suffer from gum diseases. According to one industry expert, modern brushes equipped with position sensors and a Bluetooth system are able to monitor the quality of cleaning in real time and make recommendations on oral hygiene.

In addition to evidence of the positive impact of electric toothbrushes on oral health, scientists at Greifswald University recorded an increase in the popularity of these devices: if at the time of the start of the study only 18% of its participants used electric toothbrushes, then by the end of the observation their share increased to 37%. The trend is also confirmed by the fact that only from 2012 to 2016 the market share in electric toothbrushes grew by 6%.

The researchers also concluded that it is possible to recommend the widespread distribution of electric brushes.
