If your oral hygiene isn’t at the top of its game and frankly, just an annoying thing to deal with, here is the Kolibree Smart Toothbrush ($TBA). The first toothbrush of its kind connects with bluetooth to a free app you can download to track how well you’ve brushed your teeth, for how long, and what you can improve on next time. The app can also set reminders for when to brush and you and your dentist will probably thank you for investing in something like this.
