Is it normal not to move the root of the tooth in orthodontic treatment?

I wore braces for about four years. The treatment plan was to move the premolar into the canine position and create a premolar space for a dental implant. At the end of the treatment, the space between the crowns was perfectly opened, but the one between the roots was not opened enough. Is this normal? Should the roots of the teeth not be in the upright position?

Yes it is.  It is all about the connection, the periodontal ligament (“peri” – around, “odont” – tooth). The ligament consists of a group of fibers made of a protein called collagen. These fibers are what anchor and suspend the teeth in the bone. They join to the root surfaces by inserting into a substance appropriately called cementum that is deposited by living cells. On the other side of the ligament, the fibers insert into bone that is very much alive. The total ligament is like a hammock, allowing teeth some movement in their sockets, and through which they are able to respond to the stresses of biting (force).

This is a very common thing that can happen. The roots need to be bodily moved in order to have room for the implant. When you look at teeth, it looks like there's room. An x-ray shows otherwise. Certain directed forces need to be applied to the teeth next to the space in order for the roots to be apart enough for an implant. Once this happens, the roots will be more upright.
