#asktheexpert My son is two years and 8 months old. He doesn’t like to brush and when he does, he just eats the paste. Some times he chews the brush. When I try to brush his treats, he doesn’t cooperate. Sine a month I have seen one of his molar teeth has become slightly black. I am worried that he has a cavity. Can cavities be treated for kids at such young age? What precautions can we take to ensure good health of his teeth.
