braces

Maggieee
So has anyone had a tooth taken out then had to get braces to pull the tooth behind it up to the gap where the other tooth was? If so can someone please tell me what that was like, because I may have that happen very soon 
Edit: I have straight teeth, but one of my teeth at the back of my mouth is completely decayed on the inside and probably needs to be taken out. If they take the tooth out I will have to get braces so I can fill that gap in with the tooth behind it.
