Dental office

I went to the dental office today. I went to by bus. It took about 15 minutes. My purpose is...pull out my wisdom tooth. I was a little nervous, because it is like a small operation. My dental doctor will prick the needle of anesthetic and cutting my gum, after that she will sawing my gum. It is seems ache, isn't it? So, I was nervous, but she did just explanation for me today. I was disappointed to this. I was preparation for operation. Maybe I'll go 2 weeks later.
