Every time we eat, food is trapped between teeth and inside grooves on chewing surfaces seen in the photos. Plaque Bacteria change fermentable carbohydrate like sugar to acid, which demineralises tooth where saliva does not have access to neutralise acid and repair demineralised tooth.

Almost all cavities occur between teeth and inside grooves below where the brush, toothpaste, mouthwash, chewing gum and saliva cannot reach.

The Supertooth Kit has been developed and tested for school or home use to colour plaque at gum margins and between teeth with food dye and helps compare different ways to remove food and plaque and improve access for saliva to neutralise acid and repair demineralised tooth conveniently after eating.

Experiments with a glass model of a fissure in a groove simulate chewing and helps understand how food is trapped while eating. Some foods displace other foods and some are hard to remove. Chewing fibre like celery after eating helps force saliva inside groves to remove food, neutralise acid and repair demineralised tooth. Chewing fibre with a sugarless food that is hard to remove before eating, seals grooves in back teeth where 80% of cavities occur and the brush cannot reach. This seal helps prevent food being trapped while eating similar to fillings and fissure sealants that dentists place in grooves.

Chewing Barium Sulphate with the dental foam strip in the Supertooth Plaque Watch Kit before dental x-rays of back teeth, highlights where food is trapped in grooves and helps the dentist advise mineralisation therapy, sealants or fillings if necessary. This can show how sealant foods work similar to a glass model of a groove made from two strips of glass clamped together to simulate chewing

Dental fillings and sealants often last for years but sometimes break down at margins, which may not be detected till a cavity suddenly appears. Chewing a sealant food, tablet or confection before eating provides temporary protection while eating and helps remove any trapped food after eating.

Chewing a fibre food like celery or the foam strip in the Supertooth Plaque Watch Kit after eating forces saliva around teeth and inside grooves to help remove food, neutralise acid and repair demineralised tooth during rest periods between meals or snacks.
