INSTRUCTION DESCRIPTION OF THE INVENTION (1) Field of the Invention The present invention relates to a toothbrush having an improved cleaning brush head. Prior Art Toothbrush systems are used to remove plaque and debris from the surface of the teeth to clean the teeth. - The traditional toothbrush of the bristle trim is subjected to the ability to remove plaque and along the teeth in conformity with the interdental space between the teeth. In addition, this brush has limited ability to retain the tooth powder used to clean the teeth. During brushing, the dentifrice typically slides through the tuft and out of contact between the bristles and the teeth. Therefore, the tooth powder is often spread over the mouth rather than concentrated on the contact of the bristles with the teeth. Therefore, in order to make the cleaning rate, the invention has a toothbrush that provides a superior cleaning effect with the new Linjie component measurement (10). In one aspect of the invention, a toothbrush includes a brush head having a plurality of tooth cleaning elements extending from a base surface. The tooth cleaning elements generally define a ring arrangement for better retention of the dentifrice near the contact between the bristles and the teeth for more effective cleaning. In a preferred configuration, each loop is constructed of a plurality of independently deflectable cleaning elements to maintain user comfort and provide better tooth cleaning. In another aspect of the invention, other cleaning elements are disposed within the cleaning elements that make up the loop. In this configuration, these central cleaning elements are strategically positioned 25 to maximize the cleaning effect of the retained dentifrice.
