Chalky teeth, or more technically, Molar-Incisor Hypomineralisation is when the enamel on the 6 year old molars does not form properly. When the teeth erupt they are brown and can crumble leading to pain, distress and often extraction. Research into the condition which affects one in six children globally has been patchy and the cause or causes are still not understood. Dorothy Boyd is a paediatric dentist at Otago Dental School who has researched chalky teeth.
Dorothy joins Kathryn along with Professor Mike Hubbard who is a New Zealander leading a world wide campaign to get more research funding so dentists can better understand what causes chalky teeth and how to prevent it.
