I would try to find a vet that uses gas, twilight, instead of the other, I am lucky my vet knows the risk on toy breeds with anaes. so he uses what the dentist use on you for surg. try to find one that will do that call around it's safe and the babies recover in a few hours, I am in N.c I searched a long time to find the right vet and he is not cheap, bt my babies are worth the extra$$ good luck, on the teeth try for now some cow hooves, and nylon bones, my chippers teeth didn't all come out untill he was a year and a half old, I would give him lots of raw hides/ chew toys/ etc and wait just a little longer before I would have the teeth pulled, thats what my vet told me to do and it worked, didn't have to get one toothe pulled, he is only 9 months, that's how old my chipper was when I became concerned, you do have to watch out for some of these vets they are after the $$ , give him alittle more time on his teeth, as for fixing him, again that is a good move but look around for a vet like mine, and you will have no worries, good luck to you and your baby,
