My 4 year old was diagnosed with a crossbite?

My son went to the dentist a while back and I was told that he has a crossbite(underbite). Anyone out there with any experience with this? He's got an appt with an orthodontist in June. What can we expect? I'm sure he'll have to have the palate expander as well as braces as he gets older. How bad does the palate expander hurt? Does it work? When will he get it(what age)? I guess I'm just looking for some re-assurance that he'll come out of this OK. Thanks for your time.

Would it be a waste of money to take him to the orthodontist so early? His dentist suggested that at the least, he be seen so that the orthodontist can give me a timeline as to what needs to be done when.

Yes i agree with the other Doc in terms of treating a cross bite, but i would recomend that you wait for the eruption of the first molars. These erupt at six to seven years old. They help determine the position of the rest of the permanent dentition. You can do it now, but it will probably will be less efective and you might have to do it again if these molars erupt in a crossbite pattern. orthodontist recomend an evaluation at seven years old, its at this time that treatment can be more effective because the fist molars have erupted.
