Properly planned orthodontic treatment will align the teeth while keeping them surrounded by bone on all sides. In theory, teeth can be moved out of the bone as a result of incorrect treatment. The teeth sit within what is called the alveolar ridge – a horseshoe-shaped ridge of bone made up of soft inner bone and a thin outer shell of hard bone. If the teeth are moved orthodontically within the limits of the soft bone, they will not be pushed out of the bone. If, however, a tooth is pressed until it comes out through the hard bone, there will be no bone around its root in that area, only gum. The gum will not necessarily recede along with the bone, or it may do so years after orthodontic treatment. Widening the bony base is only possible while a person is still growing (in childhood and the teenage years), or with surgical methods in adults. We are limited in how much we can widen the dental arch in adults, because the bone doesn't widen with the teeth.
This answer is for general information. Your own case needs an examination by an orthodontist.
