• tooth-brushes usually consist of a brush-hotly, in one face of which are set the bristles, and of a handle, generall y formed in one piece with the brush-body, being merely a prolongation thereof, or, if formed of a separate piece, rigidly attached to the brush-body, so as to practically constitute, with the latter, a single rigid piece.
• a brush very inconvenient instrument for the purpose intended because the crowns, and particularly the inner faces of the teeth, are accessible for a brush of this shape only with difficulty, and not without disagreeable distortions of the mouth of the user, and a thorough cleaning of the said parts of the teeth with such an instrument is barely possible.
• tooth-brush the main feature of which consists in the fact that the brush-body not only forms a separate piece from the handle and is united thereto, as hereinafter described, by means of a swivel or other joint, so that the brushbody can assume a great variety of different positions with regard to the handle, according to the form of the surface of th'eteeth with which it is brought into contact, but. the bristles are so disposed in this swiveling body that when the brush is upon the crowns or ends of theiteeth at the same time that the other portions act both upon the outside and inside of theteeth.
• the bristles are so disposed in this swiveling body that when the brush is upon the crowns or ends of theiteeth at the same time that the other portions act both upon the outside and inside of theteeth.
• Our invention consists in making the brushbody laterally curved and in setting the brisand useful Improvement bone, or any suitable material.
• this brushbody tles in its concaveface, so that when in use this brushbody acts simultaneously on the inner and the outer faces and on the crowns of the teeth.
• Figure 1 is a front view

• the brush-body is shown slightly inclined with regard to the handle.
• This brush-body 2 is the brushbody, curved laterally, as represented, with the bristles 3 set in the concave side, so that they present three facestwo opposite each other and the third between the two.
• This brush-body 2 is loosely mounted on the extremity of the handle 1 by means of a pin or rivet, 4, which constitutes a swivel-joint.
• a slight longitudinal curvature may be given to the brush-body, so as to accommodate it more or less to the curved line of the jaw.
• a tooth-brush composed of a handle and of a curved brush-body swiveling thereon, and provided with bristles on the inner side of such curve, adapted to span the teeth and also simultaneously to act upon the crown and upon the inner and outer faces of the teeth.
