All I can say is I wouldn't do it! It is way to wrisky!! Is it really worth the wrisk? I was told Timmee needed baby teeth pulled out! Well when I looked into it, I had second thoughts! 3 years latter, his baby teeth fell out on there own!9 And I have them all) he is perfectly fine! Any time a small toy breed is put under for anything it can have fatal results!!!! Unless it's life threatening, why ever take that wrisk just bacause the Vet says so! remember they are out to make big bucks on folks who love there Yorkies so much and only want the best no matter what the cost!!! Just PLEASE give it more thought!!! Give nature a chance...
