Second opinion!?

I took my 3 year old daughter to the dentist specialist for kids due to a chipped tooth and a cavity due to that, they examined for a few minutes she made a noise didn’t even move and he said she’s too difficult she needs to be put to sleep in order to fix her tooth and I asked why not try the laugh gas or sleep juice to help her relax and then try the full putting her to sleep he didnt even want to try she did so good though without anything she had xrays my husbands okay with putting her to sleep but I’m not unless nothing else works she’s just so young and I don’t know should I seek a second opinion!? What would you do? Has anyone else been in this situation with their child?
