Welcome to the Supertooth Blog Supertooth and the Good Food Friends Plaque Watch school project http://supertooth.ndk.biz     http://fooddownunder.com

Plaque can be seen at gum margins with food dye in the Supertooth Project as in this photo.

Plaque changes sugar and starch to acid which demineralises tooth and eventually causes cavities.

Brushing with fluoride toothpaste toughens teeth and helps remove plaque from gum margins that could change sugar to acid.

Plaque bacteria can double every 20 minutes so it is about 8 hours before plaque buildup can convert much sugar to acid.

Saliva has access to gum margins after brushing to dilute sugars, neutralise acid and repair demineralised tooth.

Almost all cavities occur where food is trapped between teeth and inside pits and fissures in grooves on chewing surfaces where the brush and saliva cannot reach after every meal or snack. Chew fibre like Celery after eating to help saliva remove food.
