Hi, I Got An Orthodontic Treatment Done When U Was

Hi,
I got an orthodontic treatment done when u was 13 years.. got 4 teeth extracted because of creation of the space. Post the treatment I did not wear plates which made my teeth come forward like before. I recently again started my orthodontic treatment since there is no space, my doctor advised me to get my wisdom teeth removed after that he wanted to start the distalization process. But due to the calcium deficiency the screw didn't hold in my gum. Now he suggested a sugery where in he will put two cuts on the either side of my gums and he will put a plate where the screws will hold or he will strip my teeth to create space. What to do. Please advise.
