A foldable toothbrush having a self-contained storage compartment contiguous with the body of the toothbrush. A pair of storage compartments are connected to one another, one of which is, in turn, connected to an arm assembly. The arm assembly has a pair of members connected to each other. The toothbrush's bristles are attached to the outermost member of the arm assembly. In its fully folded position, the arm assembly's members fold down on one another to form a folded arm section which is folded into one of the storage compartments. The other storage compartment folds down onto the first storage compartment to yield a small, flat, cylindrical case which houses the toothbrush which can easily be stored in a purse or pocket. The foldable toothbrush is designed to be inexpensive enough to be disposable but sturdy enough to withstand repeated use.

A toothbrush with a bristle head that has densely packed hexagonal tuft holes and hexagonal cross section bristles exhibits increased bristle retention. The increased bristle retention is achieved by increasing the anchored length of the tuft staple without increasing the overall length of the staple. Where the hexagonal tuft holes are of the same area as conventional round tuft holes, and the anchoring staples are of the conventional length, the 'anchored' length of the staple is increased by 25%. Bristle retention is further increased by the increased friction of the flat surfaces of hexagonal bristles against each other and against the flat surfaces of hexagonal tuft holes.

An improved toothbrush is provided with a flexible neck to avoid damage to teeth and gums due to excessive brushing pressure. The toothbrush has a bush head made of a semi-rigid material to adequately support bristles, and a handle and neck made of an elastic material. The elastic material of the handle is comfortable in the users hands. The elastic material of the neck provides the flexibility to avoid damage due to excessive brushing pressure exerted by the user on the handle. The flexible neck is reinforced by semi-rigid arms formed integral with and ending from the semi-rigid material of the brush head. The reinforcing arms are connected by a web with spaced-apart openings. The web openings are provided to receive a portion of the elastic material of the neck to further secure the neck and the handle to the brush head.
