Dye

Plaque changes carbohydrate like sugar to acid which demineralises tooth.

Plaque is easy to see at gum margins when stained by food dye from your kitchen as in the photo. Why not stain plaque on your teeth and put a photo on facebook to promote better tooth care and www.supertoothndk.org

Disclosants at the dentist or from the chemist also stains plaque so it is easy to see at gum margins where the brush and saliva have easy access.

Few cavities occur where the brush, fluoride or saliva have easy access to remove plaque and food, neutralise acid and repair demineralised tooth when brushing or after eating.

Some 20% of cavities occur between teeth where food is trapped and the brush cannot reach.

Over 80% of cavities occur inside grooves on chewing surfaces where only a minute amount of food is trapped compared to that trapped between teeth and the brush and saliva cannot reachto remove food, neutralise acid or remineralise demineralised tooth.
