Supertooth and Good Food Friends

Simulated chewing traps chocolate inside glass model of pits or fissures in a groove on chewing surfaces of teeth.
Brushing with toothpaste cannot remove trapped chocolate or deliver fluoride toothpaste inside pits and fissures.
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 pits or fissures in grooves.

Food is left trapped between teeth and inside deep pits and fissures in chewing surfaces after every meal or snack and any carbohydrate like sugar or starch is changed to acid demineralisation All cavities occur where food is left on teeth. Though most food is left trapped between teeth, over 80% of cavities occur inside pits and fissures in grooves on chewing surfaces where the brush cannot reach and saliva and fluoride toothpaste have no access to neutralise acid and remineralise demineralised tooth. 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 to remineralise demineralised tooth.
