Plenty of people admit to bad oral hygiene; not changing bristles on toothbrush every three months and not brushing the recommended twice a day. Startup company Quip has come up with a toothbrush that is on a two minute timer with vibration reminders to change brushing positions on thirty second intervals. Also with the toothbrush, you are charged $5 every three months and you are mailed new toothbrush heads. If desired, customers can pay $10 for the brush heads and a three month tube of toothpaste (plus a two week travel tube of toothpaste). Prices per brush between $5-$40 depending if the brush is manual or electric. The mission of Quip is to help people prevent gum disease and have overall better oral hygiene.

I love this idea. It is such a need and I’m sure dentists love it too. I also think the idea of them sending you one monthly is a very good idea, so you know when it is time to change your toothbrush.
