Abstract

A dental prosthesis removal tool comprising a handle portion and a top portion, the top portion including a head portion and a beak portion. The beak portion is configured to engage both a maxillary dental prosthesis and a mandibular dental prosthesis without the tool needing to be reoriented. The dental prosthesis removal tool makes it possible for a dental prosthesis wearer to remove dental prostheses without the user placing his or her fingers inside of his or her mouth. The dental prosthesis removal tool also allows a denture wearer to remove dental prosthesis without bending, work hardening, or breaking metal clasps contained in some dental prostheses. The dental prosthesis removal tool further allows a denture wearer to more comfortably remove his or her dental prosthesis, promoting better patient compliance with maintenance procedures and oral hygiene.

providing a member having a handle portion at a first end thereof, a top portion at a second opposite end thereof, and a transition portion located intermediate said handle portion and said top portion, said top portion having a head portion located at an end of said top portion distal from said transition portion;

removing the maxillary dental prosthesis by orienting the member in a first orientation relative to a user, engaging the maxillary dental prosthesis with the maxillary dental prosthesis engaging portion of said beak portion and pulling said handle downwardly away from a maxillary jaw; and

removing the mandibular dental prosthesis, while maintaining the member in the first orientation relative to the user, by engaging the mandibular dental prosthesis with the mandibular dental prosthesis engaging portion on said beak portion and pushing said handle upwardly away from a mandibular jaw.
