Q. Hi Dr Moore, My son is almost 10 year old and today his dentist told me that he may need to pull out two of his baby teeth because the adult teeth are underneath and one of the roots of the baby teeth are still showing strong without sign of being absorbed. I am wondering if the pulling is necessary (a must) because I would prefer waiting for them naturally fall off rather than the manual intervene. Can you give me some advices on which way is the best for my son? thanks
