I am not sure what town you are in, but if at all possible please find a good orthodontist in a larger town. My husband had 8 teeth pulled (in one day) as a child to "make room" in his mouth. This was and still is a bad plan. For him he still has problems and will have to soon seek adult orthodontic work to fix some of his problems.
We have 4 kids and my two oldest ones have seen an orthodontist since the age of 7. There are many plans of action that can be taken to avoid pulling teeth. One is a pallet expander. It is a device put in the mouth that makes the pallet wider thus creating room. Now is the time to have this done as once they get too old you will loose this option.
My oldest is 12 and is now in braces and we have not had to pull any teeth. I know that even with expansion there are cases where you may still have to pull teeth, but the orthodontists that we have seen say that the expansion will still help limit the number teeth to be pulled.
We live in McKinney and I am very happy with our orthodontist. Dr. Packard and his office are great with the kids and great on your budget as well. They will start (and recommend) seeing children by age 7 for their orthodontic evaluation.
Dr. Packard is also great because he does not rush to perform work that is unnecessary or that will have to be repeated. Not all children need braces before the age of 12 but many orthodontists recommend two rounds of braces over time. In all of my children's case we have chosen the pallet expander and then once we see how much room is created we make the next decision. He gives a very thorough screening and gives you all the information you need to make an informed decision without any pressure.
I hope this helps, go with your gut and do not let the doctors pull any teeth if you are not 100% comfortable with it.
