Supertooth and the Good food Friends online school/community dental health project helps develop skills to prevent food being trapped and changed to acid while eating and helps saliva remove soluble carbohydrate like sugar from trapped food after eating, neutralise acid and repair demineralised tooth. http://ndk.biz/slideshow   Almost all tooth decay occurs where food is left trapped between teeth and inside pits and fissures in grooves on chewing surfaces after every meal or snack even after brushing. Trapped food is the source of carbohydrate that is changed to acid causing tooth decay and prevents access of saliva and fluoride even while brushing, to neutralise acid and repair demineralised tooth.   Supertooth research is developing a chewy tongue cleaning adaptor to the toothbrush head that helps force the saliva fluoride toothpaste mix inside pits and fissures under chewing pressure, after brushing to remove trapped food, neutralise acid, toughen and repair demineralised tooth. This should help reduce tooth decay especially in rural communities.   Even with the benefits of fluoride, dental health education and a $304 million oral hygiene industry, tooth decay is still the most common and second most costly diet related disease with an economic impact comparable with that of heart disease and diabetes. Chewing a few peanuts before eating helps block grooves and prevent food bing trapped and changed to acid while eating. Chewing fibre like celery string after eating helps saliva remove trapped food, neutraliseacid and repair demineralised tooth. There is a great need to have governments invest in this technology so that it is convenient effective and available to all.
