MISSION: A WORLD FREE OF CHALKY TEETH

What are chalky teeth?

Not surprisingly, being a colloquialism, "chalky teeth" means different things to different people. But what we can all agree on is that chalky teeth look different. The D3 Group has adopted "chalky teeth" as a public-friendly catch-all, meaning we're not at all fussy about how the term is used. That said, we think "chalky teeth" is a good term to use when beginning a conversation about teeth that haven't developed properly, leading to enamel that isn't as hard and resistant to decay as normal (read more).


What do they look like?

Chalky teeth can be identified where the enamel has an abnormal colour, either being whiter than normal or having shades of cream, yellow or brown. This discolouration is usually restricted to a small spot or bigger patch, but the whole tooth surface may be affected in severer cases. Sometimes the enamel appears dull and opaque and also crumbles easily (i.e. "chalky", in contrast to the shiny hard surface and translucency of normal enamel). Other times the surface enamel is shiny but irregular, with pits or grooves being visible from some angles.


What are chalky molars?

Chalky molars are the commonest type of chalky teeth and are of particular concern because they cause a lot of suffering and costs around the world. Technically, chalky molars are called "Molar Hypomineralisation", or "Molar Hypomin" for short ("hypomin" is pronounced "high-po-min"). Molars of course are back teeth and those most prone to this type of D3 are the "6-year molars" – otherwise known as the first "adult" or "permanent" molars. Other molars can also be affected including the "2-year molars" in toddlers and the "12-year molars". Sometimes in badly affected children their front teeth (incisors) can have this problem too, in which case you may hear the term "Molar-Incisor Hypomineralisation" or its abbreviation "MIH" used.

Chalky teeth issues

Chalky teeth are commonly associated with toothache and an unusually rapid type of decay – and sometimes the abnormal appearance of chalky teeth is disturbing too. These issues often create need for complex dental treatment, which itself can be problematic in terms of access to appropriate expertise and allied costs.

CHILDHOOD TOOTH DECAY

A strong correlation exists between childhood tooth decay and the tooth types most prone to being chalky (i.e. 2-year molars, 6-year molars, 12-year molars). This reflects chalky tooth enamel being less resistant to acids (from dental plaque and diet), and more prone to breakdown under chewing forces, than normal. Sensitivity of chalky teeth can make them difficult to keep clean, and the porosity of chalky enamel can give dental plaque extra places to hide. Consequently, decay can progress very rapidly in mouths with chalky teeth. For example, an Australian study found that, from age 3 years, decay was over five-times more prevalent in chalky teeth than for normal baby teeth from the same mouths - see the graph below. And as shown in the pictures below, severely-affected chalky molars can crumble badly in just a few weeks. It follows that everyone should be on the lookout for chalky teeth, starting from when each and every new tooth erupts into the mouth.
