Has anyone had gum surgery in Daejeon?

My teeth are sensitive, so I went to the dentist for a check-up, but it wasn't due to cavities or anything like that. They said I have tooth wear and my gums have receded, exposing a lot of my teeth.

In this case, I looked it up on Naver and found that they also perform gum surgery... Has anyone had gum surgery in Daejeon?
