Glass Model of a Fissure in aTooth
The toothbrush and fluoride fail to prevent cavities between teeth and inside Pits and fissures. WHY?
No2. Celery * No1. Plaque * Colouring Book

Remember these facts
* Plaque changes sugars and starches to acid between teeth and inside grooves, each time we eat.
* Fluoride increases tooth resistance to acid attack so cavities yake longer to develop.
* 80% of cavities occur inside pits and fissures on chewing surfaces where the brush cannot reach.
* Dentists can apply a sealant to prevent these cavities in grooves but they often need replacing.
* Brushing gum margins and flossing between teeth before breakfast removes plaque.
* Plaque can double every 20 minutes so it is 8 hours before significant acid attack is again possible.
* Plaque is always present inside pits and fissures to cause acid attack when eating.
* Saliva neutralises acid and repairs demineralised tooth.
* Saliva and brushing do not have access inside grooves.

Glass Model
1 Stick two strips of glass 2 cm wide and 6 cm long, together with silicone in the form of a H so there is an open pocket at each end which simulates what happens inside pits and fissures while eating.
2 Pushing one end of the glass model into green food dye and fibre like celery or dental foam almost fills that end with the dye.
3 Brushing with toothpaste or swishing in water makes no difference.
4 Pushing into chewing gum with red dye replicating the chewing action makes little difference.
5 Pushing into fibre like celery or dental foam removes all the dye.
What does this mean. Left click on the start of the line below and slide down 2 lines to see the answer.
Chewing fibre like celery after eating removes food and forces saliva around teeth and inside grooves to neutralise acid and repair teeth.
Cheese forms a barrier that is hard to remove so prevents acid attack while eating
1. Chew some cheese and put it in a 35 mm opaque film container with some yellow dye and fibre like celery. Push one end of the glass model into the mixture and not it fills the fissure.
2. Push that end of the glass model into confection, bread and blue dye. It cannot penetrate the cheese.
3. Brushing and pushing into chewing gum and red dye makes no difference.
4. Pushing into celery starts to wash out the blue confection.
5. Continual pushing starts to remove both confection and cheese, but takes longer to remove it all.
