US Patent:

Filed:
Mar 23, 1992
Appl. No.:
7/855584
Inventors:

US Classification:

Abstract:
This invention directs itself to a subgingival toothbrush (10) for insertion of first and second sets of bristles (36 and 38) below the gum line (22) of a user. First and second sets of bristles (36 and 38) are adapted to be oscillated and abrasively contact a tooth surface (20) below the gum line (22) to disrupt bacteria adhering to the tooth surface (20). The first and second sets of bristles (36 and 38) are encapsulated by an encapsulating pair of sleeve members (40 and 42) to provide stabilization of the first and second sets of bristles (36 and 38) when in operational use. In this manner, first and second sets of bristles (36 and 38) can optimally be inserted beneath the gum line (22) of a user (14) for abrasive action against the tooth surface (20) and aid in controlling periodontal disease.
