I do think that some people are genetically predisposed to tooth decay, however careful they are about dental hygiene.
Although I didn't have many sugary drinks as a child, I did eat sweets every day, and tooth brushing in our house was very haphazard. Although I did have a lot of fillings as a child, at the age of 64 I still have all but two of my teeth and healthy gums (touch wood).
My mum hasn't been to a dentist since she was 9 and has never been careful about dental hygiene but at the age of nearly 94 still has her own (admittedly pretty ropy) teeth. Her 95 year old brother has all his own teeth.
So Harry and family are coming back!
World Class Museums - why are they free to everyone?


from me. Proper parenting was indeed the idea!
