· Even with fluoridation, oral hygiene, dental health education
and fissure sealants, tooth decay is still the most common and
expensive food related disease with the economic impact of heat
disease, diabetes and obesity.

· Almost all cavities occur where food is left trapped after
eatng, between teeth and inside grooves on chewing surfaces where the
brush, toothpaste, mouthwash, chewing gum and saliva, cannot reach.

· Over 80% of cavities occur inside grooves on chewing surfaces
where saliva and fluoride have no access and very little food is
trapped compared to that trapped between teeth.

· Food left on teeth after every meal or snack is the source of
carbohydrate like sugar that cause all cavities. Particularly food
trapped inside grooves under chewing pressure.

Dental treatment with fillings or fissure sealants on chewing
surfaces, prevents food being trapped inside grooves and reduces
decay progression a further 50%.

Few cavities occur, on tongue, cheek and lip surfaces of everybody in
both fluoridated and non-fluoridated areas, where food is not left on
teeth and saliva has easy access after eating and also fluoride has
easy access when brushing to neutralise acid and repair demineralised
tooth.

Tooth decay is easy to prevent on all tooth surfaces where everybody
in both fluoridated and non-fluoridated areas, has better evidence
based Dental Health Education that develops simple convenient habits
that do not leave food containing carbohydrate like sugar on teeth
after eating while fluoride and saliva have easy access, particularly
when brushing to neutralise acid and repair demineralised tooth.

Supertooth and Good Food Friends is a better dental health education
project that has been developed online for schools, communities and
dental health professionals with teaching aids including a glass
model that shows how food is trapped under chewing pressure,
displacing previously trapped food.

Some foods like nuts, are hard to displace. Chewing sealant foods
like nuts or cheese before meals or snacks, displaces previously
trapped food and helps prevent food being trapped and any
carbohydrate changed to acid.

Chewing such sealant foods, special formulations or celery string
after eating, helps saliva displace trapped food, neutralise acid and
repair demineralised tooth.

While the brush has easy access to clean tongue, cheek and lip
surfaces of teeth, trapped food prevents access of fluoride
toothpaste and saliva between teeth and inside grooves to neutalise
acid, repair and toughen demineralised tooth like on accessible
surfaces.

Chewing toothpaste on the end of a special NDK foam strip, forces the
toothpaste between teeth and inside grooves, promising much greater
prevention of tooth decay within about two years, for adults as well
as children in both fluoridated and non-fluoridated communities.

Fluoridation is not universal, and not fully effective without a
project like Supertooth.

· Fluoridation greatly reduced tooth decay but took ten years
between 1976 and 1986 to reach maximum effect, and only for children;
not for adults.

· After fluoridation, dental health education and oral hygiene
have made no further reduction in tooth decay and needs to be more
evidence based.

· There has been an increase of 21% in cavities for 6 year old
children since 1996.

· Fluoridation is still not available in many communities,
rural areas, some cities like
