Chewing
|
Chewing displaces previously trapped food between teeth and inside deep pits and fissures in grooves on chewing surfaces while eating every meal or snack.
Trapped food is the source of carbohydrate that is changed to acid causing cavities.
Almost all cavities occur between teeth and inside grooves on chewing surfaces where Recaldent, saliva, mouth wash, brushing and fluoride have poor or no access as seen in the glass model experiments.
Though most food is trapped between teeth,over 80% of cavities occur inside grooves where the brush, and saliva, fluoride toothpaste, etc. have no access.
Chewing fibre or scouring products like celery string helps force saliva between teeth and inside grooves to neutralise acid and repair demineralised tooth.

Chewing products like nuts or cheese before eating, helps block food being trapped while eating.
Chewing non-cariogenic sealant products like nuts or cheese after eating helps displace trapped food.
Chewing toothpaste on one end of a strip of NDK Foam, forces the toothpaste between teeth and inside grooves on chewing surfaces where almost all cavities occur and the brush cannot reach. The saliva fluoride mix helps neutralise acid, toughen and repair demineralised tooth. |
