ABSTRACT:
Retractors discussed herein include lip retractors that have four channel retainers to retain four portions of the lips. The four channel retainers are attached to four resilient members, which are adapted to bias the four channel retainers outwardly away from one another, which in turn retract the portions of the lips that are retained by the four channel retainers to expose the teeth and/or mouth. Optionally, the retractors may be equipped with a tongue retainer. If equipped, the tongue retainer is adapted to limit the tongue to further expose the backside of the teeth.
