This is the key sentence, IMHO: > Once confirmed to have no ill effects on the human body, it will be aimed at treating children aged 2 to 6 who exhibit anodontia. This greatly limits usefulness of the whole enterprise. The problem is that this condition is not likely to be found at that age, it's found later when the problem is evident to parents. What is actually needed is some treatment for teenagers or young adults.
