The new National Oral Health Plan has a strong focus on prevention of tooth decay, our most common yet most preventable disease affecting over 11 million Australians each year, where frequent acid demineralisation exceeds saliva and fluoride remineralisation of teeth.


1.  2.  3.  4. 


Over 80% of cavities occur inside pits and fissures on chewing surfaces 1. where food is trapped 2. and resident plaque bacteria change any carbohydrates like sugar to acid that demineralises tooth and brushing saliva and fluoride cannot reach to clean, neutralise acid and remineralise tooth.    


X-rays 3. are often needed to find these cavities that used to need filling, 4. but with early detection, dentists can place costly fissure sealants over chewing surfaces to block food access before cavities develop and prevent decay.

X-ray tomography of pits and fissures in back molar teeth gave accurate dimensions of these developmental faults that helped make 3D models 5. of where food is trapped which is similar to sealants that had been forced inside pits and fissures with an elastomeric type of gum and the teeth dissolved in acid 6..

Glass models7. were made consisting of two squares of glass clipped together by a fold back paper clip. These replicate how chewing forces the first bite of food inside pits and fissures, which brushing cannot reach. However replicating chewing celery after eating forces saliva inside trapped food to dilute any carbohydrate like sugar, neutralise acid and help remineralise tooth. www.youtube.com/suprtoothndk


Other promising options were explored that block food access to prevent demineralisation and increase remineralisation.


 Most other cavities occur between teeth where food is trapped and resident plaque change and carbohydrate in food or drink, to acid that demineralises tooth and brushing has limited access. 



That is why it is important to floss and use interdental brushes to remove plaque and food from between teeth after eating to reduce demineralisation, improve saliva access to neutralise acid and help remineralise tooth. This also to improves fluoride toothpaste access while brushing to remineralise tooth.


 Few cavities occur on other surfaces that are protected by saliva and are easy to brush even though most plaque is easy to see at gum margins. However frequent exposure to carbohydrate rich food and drink can cause demineralisation to exceed remineralisation resulting in decay.


Supertooth with RMIT has developed an opt-in database so every year families and individuals can update their oral health status and record any cavities or fillings inside chewing surfaces and between teeth that are difficult to clean and on other surfaces that are easy to brush as well as fissure sealants, decayed, missing teeth and filled teeth, so they can compare their personal oral health with postcode, state and national averages.


Parents can also register to send baby molar teeth that fall out from children to the Tooth Fairy to measure developmental faults in chewing surfaces that trap food where most cavities occur and brushing can't reach.


This will motivate better personal tooth care, identify those surfaces most affected and monitor the new 10 year national oral health plan.
