Glass model of a fissure where over 80% of cavities occur and brushing cannot reach trapped food that results in enough acid demineralisation over thousands of meals or snacks to cause over 80% of cavities that saliva and fluoride have no access to remineralise the demineralised tooth.
Why is tooth decay still the most common global disease affecting every family, including 11 million Australians each year, when it is easy to prevent.
Over 80% of cavities occur where food is left trapped inside pits and fissures on chewing surfaces and the brush cannot reach while saliva and fluoride toothpaste have no access to remineralise demineralised teeth.
Fissure sealants placed over chewing surfaces, block food being trapped and halt the decay process. Chewing pressure forces sealant deeper inside pits and fissures.
See the glass model of a fissure experiment that shows how food is trapped under chewing pressure displacing previously trapped food and brushing cannot reach.
However chewing some foods like nuts or cheese before eating, acts like a sealant to help block food being trapped while eating.
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.
