Supertooth and Good Food Friends

Simulated chewing traps chocolate inside glass model of a groove on chewing surfaces of teeth.
Brushing with toothpaste cannot remove trapped chocolate or deliver fluoride toothpaste.
Chewing toothpaste on a foam strip, forces fluoride toothpaste to displace chocolate inside the glass model.
Chewing Barium Sulphate on a foam strip before x-rays shows where food is trapped in grooves.

Food is left trapped between teeth and inside deep pits and fissures in chewing surfaces where almost all cavities occur and the brush cannot reach. Trapped food prevents access of saliva to neutralise acid and repair demineralised tooth after eating. Also food prevents access of fluoride toothpaste between teeth and in grooves to toughen demineralised tooth while brushing. Floss and chew toothpaste on a foam strip before brushing to help fluoride access between teeth and inside grooves.
