Yes, go for the consultation... I have a family friend who is both a pediatric dentist and an orthodontist. In fact, there are very few in PA that are both ped dentist and orthodontist. You would think that I would be on top of things, right? Well, I missed a six month check-up and just got my kids there in July. In the year between visits, my DD10 lost many teeth and began to get her 12 yr old molars. My friend told me if I had waited a few more weeks, DD10 would not be able to get an expander and would have to have teeth pulled instead!
Thankfully, we have the expander. He also showed me the expander my DD7 will be getting in a few years.
I think that there are so many advances in this area... Not many kids have "headgear" anymore, but there are a number of different types of expanders that do the same job. Also, pulling teeth is often avoided by using the expanders...
Go for the consultation. It will put your mind at ease. Good luck!!
