My Dentist Wants To Pull My 1 Canine Out Because

My dentist wants to pull my 1 canine out because of it's position as well as all my wisdom teeth. He said he cannot save it and I'm worried my teeth won't match. I am 29 years old and the dentist stated he wanted to pull my eye tooth on one side only before braces because he can't save it and pulling it down will kill the tooth it's on top of. I'm afraid my midline will be off and look funny any advice appreciated. Also the bottom teeth they want to pull the one in the back and I will only have three small teeth then two cuspids will all this look funny? I also have one person wanting to pull all wisdom teeth and another saying if they aren't hurting me then leave them alone especially bc the left bottom has bone missing already and can damage the roots to the tooth on side of it from pulling it out. I have pictures and X-rays if you would like to review them. I live in a small town and don't have many dentist any advice is greatly appreciated.
