Recording smart phone video “selfies” of tooth-brushing can help people learn to improve their oral health care techniques, according to a new study.

The “selfie” fad may be causing a number of unfortunate incidents across the globe but it also has its upside. According to a new study, recording video “selfies” while brushing teeth can help improve a person’s oral health.

The study’s participants used stands to hold their smartphones and film themselves as they brushed their teeth. Even though the period of time for which the participants brushed did not change, the researchers found an overall eight percent improvement in their skill. The brush strokes were noted to be more accurate and increased in number.
