It’s official! Taking a selfie helps us clean our teeth more efficiently


Recording video selfies of ourselves brushing our teeth can help improve oral health care techniques.


That’s according to a news study that used propped up smartphones brushing at home.

Researchers saw an increase in the accuracy of brush strokes, an increase in number of strokes and an overall 8% improvement in tooth-brushing skill if not an increase in the length of time participants brushed.

While most people have the ability, motivation and desire to brush their teeth properly, they often do not because of improper techniques — and opportunities to improve such skills can be few.

‘Often, tooth-brushing is learned and practised without proper supervision,’ said Lance T Vernon, a senior instructor at the Case Western Reserve University School of Dental Medicine and co-author of the study.

‘Changing tooth brushing behaviours, which are ingrained habits tied to muscle memory, can take a lot of time and guidance.’

‘Our study suggests that, in the future, recording these selfies can help shift some of this time investment in improving brushing to technology,’ added Vernon.

‘Patients can then receive feedback from dental professionals.’

The very act of recording a selfie may disrupt ingrained habits, making participants conscious of their brushing and reinforced staples of behaviour change, including the process of memory formation, association and creating new muscle memory.

While the results of this small pilot study, published in the Indian Journal of Dental Research, are promising, researchers suggest that these findings are of more importance in proving the selfie concept is useful in a dental setting.

Video and picture selfies are increasingly used in medical fields to assess, monitor and determine the progression of diseases and effectiveness of treatment —a new area of gathering data known as mobile health, or mHealth.

‘To our knowledge, this is the first report using selfies to study tooth-brushing behaviour,’ Vernon said. ‘It’s a start at an mHealth strategy to create new habits, helping dentists and patients focus more on prevention, rather than on fixing problems once they occur, which can too often be the focus in dentistry.’

‘The cost of an app could be minor, while potentially there could be major long-term benefits to a user's oral health and quality of life,’ Vernon said.

‘Dental care can be inaccessible because of cost and access. It's possible dental selfies and other mHealth strategies on phones can become an important part of oral health prevention and diagnosis in the future.’

Tooth-brushing helps avert preventable oral diseases, such as tooth decay and periodontal disease, although its effectiveness depends on brushing technique.
