Brushing Your Teeth Never Sounded So Good


Do you find brushing your teeth boring? If so, you're not alone.

However, if that boredom leads to inconsistent or poor quality brushing, that can be bad for your oral health. Over time, poor brushing habits can lead to cavities and gingivitis, not to mention bad breath.

Researchers have known for some time that positive reinforcement can encourage brushing. However, these attempts at positive reinforcement were thought to be too abstract, limiting their effectiveness. Examples included the simple use of music or visual progress indicators.

A team in Japan proposed a different approach: modulating the sounds associated with brushing to connote both comfort and accomplishment as the brushing continued. Their subsequent experiments demonstrated that increasing the sound gain and manipulating frequency can indeed affect feelings of comfort and accomplishment.

The researchers still have more work to do, as it is still unclear what the optimal sound gain, frequency, and sound filter should be to maximize the effect. Further studies are planned. The hope is that the researchers can find a way to make brushing more interesting and rewarding, which everyone agrees sounds great.

The study was published in the International Journal of Arts and Technology.
