Hello - I have a 4 and 3 year old and am here to say that I don't know what your reading, but your child does not have to go to the dentist until age 3. In fact can you imagine trying to get your child to sit in a dental chair at age 1! I think that what your reading is trying to emphasis introducing a dental routine to your child at about age one, give them a toothbrush and get the habit down. Unless you notice a problem with your childs teeth, wait until 3.
