According to an aspect of some embodiments of the teachings herein, there is provided a method of creating a retainer for aligning teeth of a specific user. The method includes creating a mold of the teeth of the specific user. Indentations are then placed into the mold, each indentation corresponding to a point at which pressure is to be applied to one of the teeth of the specific user. Using the mold including the indentations, forming a retainer, such that the retainer includes protrusions, each of the protrusions corresponding to one of the indentations. The resulting retainer matches the shape of the teeth of the specific user except for the protrusions, and when the retainer is worn by the specific user, each of the protrusions pushes on a specific tooth at a specific pressure point on the specific tooth, thereby causing the specific tooth to rotate, tilt, or move.
