Referring more particularly to the drawing, From the above construction taken in connecwherein I have illustrated one of the embodition with the accompanying drawing, it will be ments of my invention, it will be noted that the apparent that I have provided a simple and inbristle carrying head is formed of a plurality of expensive type of tooth brush, wherein the bris- 100 sections indicated at 1, 2 and 3. While, in the tle carrying head is formed of a pluralityof present instance, I have illustrated the head as yieldably connected sections, so that when the formed of three separate sections, it will be apbrush is used upon the teeth, the bristle carryparent that various numbers of sections can be ing head will readily conform to the contour r used for carrying out the idea. thereof.

Each one of the sections 1, 2 and 3 carry the When the brush is brought into engagement usual type of bristle indicated at 4 and the sev-- with the teeth upon the inner side or the outer eral sections have embedded therein and extendside, it will reach all parts of the teeth during ing longitudinally of the head, a yieldable plate the cleaning operation and principally the in- 5 which tapers longitudinally with the larger porside of the teeth which are usually inaccessible and difficult to clean with the standard, rigid brush head.

The device is very simple and inexpensive in construction and can be manufactured and placed on the market at a low cost.

Attention is directed to the fact that the yieldable plate 5 must necessarily be formed from a non-corrosive metal whereby the device as a whole is absolutely sanitary.

While I have shown and described the preferred embodiment of my invention, it will be apparent from the foregoing that slight changes may be made in the construction when putting the invention into practice without departing from the spirit of the same or the scope of the appended claims.

I claim:

1. A tooth brush including a handle, a series of spaced bristle carrying sections arranged in alinement and the inner of which is connected to the handle, and a flat flexible strip embedded in all of the sections, said strip being normally substantially straight and having its opposite longitudinal side edges converging from the inner end thereof to the outer end in substantially straight lines and to cause the outer end of the strip to be of materially less width than the inner end, whereby to allow the sections to flex in a substantially uniform curve corresponding to the curvature of the inner and outer surfaces of the teeth.

2. A tooth brush including a handle, a series of spaced bristle carrying sections arranged in alinement and the inner of which is connected to the handle, and a flat flexible strip embedded in all of the sections, said strip being normally substantially straight and having its opposite longitudinal side edges converging from the inner end thereof to the outer end in substantially straight lines and to cause the outer end of the strip to be of materially less width than the inner end whereby to allow the sections to flex in a substantially uniform curve corresponding to the curvature of the inner and outer surfaces of the teeth, and said strip having a pair of notches for each of the sections and into which the latter extend whereby to anchor the sections to the strip, the notches of the respective pairs occurring on opposite side edges of the strip.
