This.
Floss twice a day, brush once, stop eating (and more importantly drinking) absolute chemical garbage and your teeth will last as long as your bones.
Which won't be very long if you've bought into the pharmaceutical industry of late as much as you've bought into the dentistry one.
Mother nature gave you teeth, do your part to keep them or lose them.
It's up to you.
Not (((them))).

TLDR: physically clean your teeth, especially between them, at least once a day, and leave the chemical cleaning to your saliva, the stuff your body produces not least of all for that purpose.
