A disposable dental brush for applying various dental materials onto a tooth in thin, even coatings, e.g. etchants, sealants, bonding agents, tints, opaquers, varnishes and the like that includes an elongated straight handle having a tuft of bristles connected to one end thereof. The elongated handle is constructed so as to allow the portion thereof adjacent to the brush end relative to the longitudinal axis of to be readily bent so as to angularly dispose the brush end the handle. The arrangement is such that the brush can be used either as a straight brush or an angularly bent brush to reach difficult areas of the mouth or teeth. Also, the brush is made of inexpensive plastic material so as to render it readily expendible or disposable after each use.

A readily disposable dental brush for applying various dental materials to a tooth in thin, even coatings comprising an elongated tubular handle formed of a plastic material and having a continuous, uninterrupted bore extending therethrough, said bore opening to at least one of said handle, a tuft of bristles partially inserted into the open end of said bore, said tubular member allowing said tuft of bristles to be inserted therein to a selectable predetermined length, means for securing the bristles therein, said handle having a hinging section formed along said tubular handle spaced from said open end and adjacent said tuft of bristles adjacent the brush end of the handle, said hinging section being defined by the opposed tubular wall portions of said handle being disposed contiguous to one another to define a flattened portion, whereby said hinging section is rendered sufficiently rigid for allowing said handle to maintain its co-linear elongation for use as a straight brush and yet being sufficiently flexible to permit said brush end to be angularly disposed relative to the longitudinal axis of said elongated handle and said flattened portion imparting a memory to said tubular member to maintain said brush end in said angularly disposed position.
