I can't wait for daily teeth brushing to be a thing of the past. It amazes me we've had so many technological advances while still having such primitive mouth cleaning solutions.

There's people that basically never have to brush their teeth, why can't their magical bacteria be used by everyone? I recently asked a dentist in training and they told me the bacteria would die after eating the plaque. Even if you have to regularly re-add the bacteria, it doesn't seem like that big of a deal. You could make a lozenge which you suck on once a week, and it's still less effort than brushing daily.
