If you or your husband had braces and you suspect that your child will have to have them, you can just let nature take it's course. However, if it bothers you or your child or you hope you may be able to get by without braces, you should probably get advice from a pediatric dentist. Many pediatric dentists will refer you to an orthodontist who will consult with you regarding your child's teeth in an attempt to stay ahead of the game and possibly avoid braces by pulling baby teeth to allow space and possibly inserting spacers. It would really be your choice.
We decided to consult with and orthodontist for my oldest son because he has a narrow jaw/mouth and cross bite similar to mine and knew it was highly likely that he would one day need braces. He did need braces, and the orthodontist did suggest pulling some baby teeth that were not budging to make room in his mouth. We chose not to do rush in with the spacer appliance and let his eye teeth grow in badly, but it all worked out because overall, he now will wear the braces for only 2 years instead of the 4 he would have had to do with the spacers. Of course it compacted our timeline to pay, but everything is turning out beautifully! Email me if you have more questions.
