Sticky, dried, and hyper-palatable foods remain in contact with teeth for extended periods, feeding bacteria and maintaining an acidic oral environment.

“so things that are really sticky and um dried I would argue so crackers or toast chips chips I mean think about if you take a handful of Goldfish crackers I haven't done that in a long time time but imagine that it's all throughout your teeth in between the teeth down in the grooves it's sticky it's just a schmorgus board for the bacteria and so what do the bacteria do when they metabolize the sugar or the flour they release acid and so if that food substrate is stuck against the tooth for a long period of time and these foods are also hyper palatable so we're meant to be just snacking and grazing hitting the Bliss point you know grab a handful go do something come back grab another handful you're just constantly feeding that bacteria so your mouth is staying constantly acidic”
