Problems solved by technology

However, using different toothbrushes for various functions is generally considered impractical and too time-consuming for the cleaning or appearance of specific areas of the teeth
[0003] For electric toothbrushes in particular, different brush heads can be used to meet specific dental requirements in different areas of the teeth, but constantly changing brush heads is inconvenient and expensive

Embodiment Construction

[0007] figure 1 The dental appliance assembly 10 is shown. The dental appliance assembly 10 includes a dental appliance carrier 12 adapted to receive a user's upper and lower teeth, and a power and control assembly, shown generally at 14 . The dental appliance carrier 12 is generally in the shape of a horseshoe, and typically comprises a plastic material. If the dental appliance carrier 12 is to receive upper and lower teeth, the dental appliance is "H" shaped in cross-section with two vertical side members 16 and 18 and an intermediate horizontal member 20, as shown in the drawings. The side members 16, 18 are generally high enough to cover the side surfaces of the teeth. In some cases, however, the dental appliance unit 12 covers only the upper or lower teeth, in which case the dental appliance unit will be "U" shaped in cross section, upright or upside down, depending on whether the appliance is used for the upper or lower teeth tooth.

Abstract

A dental appliance carrier assembly (12) is adapted and configured to receive upper and lower teeth of a user. The dental kit carrier assembly is driven such that the bristles mounted on the tooth facing surface of the dental kit assembly contact said surface and provide a cleaning effect thereto. A plurality of bristle sections (30, 32, 34, 41, 44) are secured to the tooth-facing portion of the mouthpiece assembly, wherein each bristle section has bristles having a specific configuration and are otherwise adapted to provide the associated tooth region with Cleans effectively.

Description

technical field [0001] The present invention generally relates to dental appliances for cleaning teeth, and more particularly to a dental appliance in which the bristles in the dental appliance are not identical but are different in different areas to achieve different cleaning functions. Background technique [0002] It is well known that different dental areas of the oral cavity have different cleaning requirements (or objectives) and / or appearance requirements (or objectives). But conventional toothbrushes have a single bristle zone, making the selection of specific bristle characteristics a compromise. Certain bristles in a single bristle area may be particularly suitable for cleaning interdental areas of teeth. However, the effectiveness of interdental bristles is often limited because the toothbrush is moved around the entire mouth by the user. Consequently, the positions of the bristles intended to reach the interdental spaces are not always aligned with these areas...
