Seriously - this is interesting tech but it seems like a mostly solved problem. Brush your teeth when you wake up, then floss and brush them again before you sleep.

Once it's routine (hopefully established in youth) it seems extremely easy to maintain.

dismissive advice like this completely ignores the fact you can brush several times a day and have way more dental issues than someone else due to different mouth flora.

but ya bro shoulda brushed! what is their problem!
