My grandaughter and grandson were both put out by gas to have their cavities filled. Both were around 2-3yrs.old. I was told a long time ago by a wonderful dentist that I had, whom I took my daughter to at the age of 5 and he would not fill her tooth. He informed me that by filling a baby tooth it can effect the second tooth coming in, which may have to be pulled as well. He put a screen on her front tooth just to be able to keep it until she lost it. My 2 grandchildren have already had to have work done on their 2nd teeth. If I were you I would definetly get another opinion. Good luck and see if they still have these screens available. It certainly worked with my daughter.
