Expander for our 5-year-old



our son is 5 and has recently had an expander put (on top) and bottom of his mouth because our dentist felt he had a slight cross bite and also an xray showed that his permenant teeth (not out yet) are bigger than his jaw can accomodate. It has bee a week now and even though it is all done, I am now wondering if I should have waited till he is older since it is hard for him at this age, and was it even neccessary?.


Treatment at age 5 is unusual and the American Association of Orthodontists recommends age 7. I would suggest consulting a board-certified orthodontic specialist in your area for a second opinion. You can get a list of board-certified specialists from the American Board of Orthodontists website: www.americanboardortho.com/public/.
