Abstract
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.
