I highly recommend a second opinion! Be very careful.
We had a very bad experience with the dental clinic at Denver Childrens. I had VERY specifically told them what work I agreed to and with and which I did not want them doing but once they had them in surgery they did whatever the H____ they wanted to. I was extremely upset when I found out that they had done stuff that I very specifically told them not to do because one I couldn't afford it and two they were baby teeth that were going to come out soon anyways. My experience is that dentist need and want procedures to do even more than residents and interns. I did not have to pay for the work because I had it in writing what I did and did not want them to do and since they did it anyway, they ate the costs.
In my experience, the reason it is necessary to do it in a surgery setting is because they can do everything all at once, which is not necessarily in the childs best interest.(both of my kids that had dental surgery were in pain for a week after and needed pain meds to control it) Two, they can do more things than they tell you up front with under the idea that they "didn't know" until they got in the mouth to actually do the work.
Honestly, if I had it to do all over again, if it were the baby teeth, unless the teeth were bothoring or causing pain, I would leave them alone. Once the adult teeth come in I would be very pro-active in helping my child take the best care of them as possible and would at that point take them to the dentist on a regular routine bases to prevent as much as possible. I would definetly leave those baby teeth alone though unless they were causing problems for my child in the way of pain and just make sure they were being brushed, flossed, and use a rinse such as biotine as soon as they are old enough to not swallow it.
Best advice, just be very very careful, get 2nd opinions, and really check the dentist out as much as possible.
