Absolutely. A tooth with a crown (or any type of restoration) can be moved the same any other tooth as long as its root(s) and surrounding tissues are healthy. If you are missing teeth, orthodontics can improve the alignment of the remaining teeth and enhance tooth replacement options for your dentist. In some cases where one or several teeth are missing, orthodontics can partially or completely close the spaces left by these teeth, which can either reduce or eliminate tooth replacement costs after orthodontics.
