A built-in toothpaste type toothbrush structure includes toothbrush casing, toothpaste inner tube, knob switch, toothpaste storage handle and pushing structure. The toothbrush casing includes a toothbrush head, an accommodating space, and an outlet and a socketing portion. The toothbrush casing is sheathed on the toothpaste inner tube and has a toothpaste channel inside, and the toothpaste storage handle is connected integrally with the toothpaste inner tube for storing toothpaste, and the pushing structure is installed in the toothpaste storage handle to push the toothpaste to the toothbrush head. Therefore, the knob switch can control the communication between the toothpaste inner tube and the toothbrush casing to avoid contaminating the toothpaste stored in the toothpaste inner tube, so that home and office users or students can carry and use the toothbrush for dental cleaning and oral hygiene conveniently.

A hole perforation plate has a front surface, a back surface, a thickness therebetween, and a plurality of holes, grouped into more than one arrangement of holes, wherein the more than one arrangement of holes can be identical or different compared to one another regarding the number of the holes, the shape of the holes, the size of the holes, the distance between the holes, the arrangement of the holes, and a combination thereof.

An oral cleaning unit, e.g. a head for an oral cleaning and/or treatment device, includes electrodes for generating an RF field for providing an oral cleaning and/or treatment function. The unit includes at least a first and second protruding structure, which protrude in a same general direction away from a base or support structure. Each comprises one or more electrodes. The protruding structures are arranged facing one another and separated by a space or gap which is configured so as to be able to receive a tooth pushed or inserted therein between the first and second protruding structures, and with the protruding structures extending on either side of the tooth, i.e. straddling the tooth. This allows the RF electrodes comprised by the protruding structures to reach to a location at least part way down side faces of the tooth, closer to interproximal spaces, enabling interproximal spaces to be better cleaned, and optionally also to be sensed using RF energy/fields interacting with dental features, when the electrodes are suitably driven by an RF signal.

Embodiments are directed to a tug-toy tooth brush. In one example, the tug-toy tooth brush includes a structural frame that provides support for at least one sliding element. The structural frame includes channels that guide the sliding element while sliding within the structural frame. The sliding element is configured to slide from a first position to a second position within the structural frame. The sliding element includes bristles that extrude through the structural frame. The tug-toy tooth brush also includes at least one handle attached to a distal end of the sliding element, where the handle is configured for travel through the structural frame.

An oral care implement that includes a conical tuft of bristles. In one embodiment, the invention is an oral care implement that includes a handle and a head coupled to the handle, the head having a front surface. A plurality of tooth cleaning elements extend from the front surface of the head. The plurality of tooth cleaning elements include a conical tuft that has a continuous bristle wall having an inner surface defining a cavity, the cavity having a transverse cross-sectional area that increases with distance from the front surface of the head. The plurality of tooth cleaning elements may also include a central cleaning element located within the cavity. The conical tuft may terminate in an annular top surface that undulates in height relative to the head. The plurality of tooth cleaning elements may include arcuate cleaning elements arranged in a loop about the conical tuft.

An oral care implement having tooth cleaning elements and an elastomeric soft tissue cleanser. In one aspect, the oral care implement has a handle and a head (110) coupled to the handle, an elastomeric soft tissue cleanser having a plurality of protuberances (152) extending from a rear surface of the head (110), and a plurality of tooth cleaning elements (115) extending from a front surface of the head. The protuberances (152) of the elastomeric soft tissue cleanser collectively define a convex longitudinal side profile and comprise at least one convex transverse top profile. The plurality of tooth cleaning elements (115) collectively define a concave longitudinal side profile and comprise at least one concave transverse top profile.
