ABSTRACT:
The present invention is a safety toothbrush with wear indicator. The safety toothbrush provides a safety feature to the conventional toothbrush by attaching a soft bumper to the end of the toothbrush head. The toothbrush head holds the tufts for brushing and is opposite the handle end. The soft bumper is preferably made of an impact absorbing material such as rubber, either natural or synthetic or in the form of the an air cushion, and is attached to the end of the toothbrush head by means of adhesive or embedment or both. The soft bumper is of sufficient thickness to render its effectiveness. An additional useful feature of the safety toothbrush is that the soft bumper is attached in such a manner that the soft bumper or a portion of the soft bumper will become disengaged with the toothbrush head after the toothbrush has experienced a certain amount of wear. The disengagement of the soft bumper with the head not only indicates that the toothbrush should be replaced but presents an unacceptable operating condition causing positive replacement of the toothbrush.
