A pump toothbrush having a toothpaste tube to dispense dentifrice material to top of bristle head is disclosed. The pump toothbrush has a pump head with a resilient button to create an internal vacuum force to draw the dentifrice material from the toothpaste tube. The toothpaste tube is supported by width-limiting fingers to prevent total collapsing of sidewalls resulting in blocking of its flow channel. A self-closing spout is used for preventing backflow. For a manual pump toothbrush the toothpaste tube has an oval-shaped shoulder for mating with the oval-shaped shoulder of a detachable handle for fastening the toothpaste tube by threads. For an electrical pump toothbrush, a detachable endcap connector is used for swinging out the toothpaste tube from its handle for replacement. A sonic vibration model uses rubber molding to minimize vibration on the handle. A dual-rotary model has two rotary bristle elements engaged by gear teeth.

The present disclosure provides a brushhead for an power toothbrush detachably attached to a handle of the power toothbrush, the handle including a vibrating drive shaft, the brushhead comprising: a main body defining a receiving cavity which is configured to receive at least a portion of the vibrating driving shaft, the main body including a cavity wall substantially surrounding the receiving cavity and an end connected to the handle, with an opening which is defined in the end of the main body in air communication with the receiving cavity, so that the vibrating driving shaft is capable of being inserted into the receiving cavity through the opening; and an engaging assembly mounted in a side wall of the main body, the engaging assembly comprising an elastic member, which is made by metal material; wherein, a recess is defined in the outer surface of the side wall, the elastic member is deformably received in the recess, the elastic member is elastically deformed by force provided from the vibrating drive shaft when the brushhead is attached to the handle of the power toothbrush.

The various embodiments described herein include methods, devices, and systems for customizing dental care. In one aspect, a personalized dental care device includes a first customized mouthpiece including a top cleaning tray and a bottom cleaning tray, each customized based at least in part on an electronic 3-D dental model of a respective user's mouth. The personalized dental care device includes one or more power mechanisms, configured to couple with the first customized mouthpiece, and to transmit energy to at least one cleaning tray of the first customized mouthpiece. The personalized dental care device is configured to be operated in a plurality of modes. Each respective mode of the plurality of modes is associated with a different method for providing oral care.

An oral care system that includes an oral care implement and a tracking attachment. The oral care implement may include a handle and a head. The tracking attachment is detachably coupled to the oral care implement. The tracking attachment may include a first component comprising a first housing having an inner surface that defines a first cavity and a second component comprising a second housing having an inner surface that defines a second cavity. When the tracking attachment is coupled to the oral care implement, a first portion of the handle is positioned within the first cavity and a second portion of the handle is positioned within the second cavity.

A magnetically driven electric toothbrush head includes a brush body, a movable board and a screw cap with a cavity. A fixed frame is arranged in the cavity. Two spaced twisting plates are connected between the fixed frame and the movable board. The movable board is connected with a driving shaft extending through the fixed frame and the elastic cover is fixedly connected with the brush body. The bottom of the movable board is provided with permanent magnets. When the screw cap is connected to the brush handle, under the magnetic effect between the electromagnet and the permanent magnets and the distortion restriction of the twisting plates, the movable board drives the driving shaft and the brush body to rotate reciprocatingly and synchronously. The lower part of the twisting plate is exposed to form a twisting section which is connected to the driving shaft via a rubber strip.

An electric toothbrush head includes a brush body. The brush body includes an insertion cavity and a plug-in unit inserted into the insertion cavity. The plug-in unit includes a friction arm and an elastic arm cooperatively forming a pressing channel therebetween. The elastic arm has a bending section with a pressing surface facing the pressing channel. The friction arm has a convex section with a friction surface facing the pressing channel. The pressing surface and a concave-convex structure of the convex section press opposite sides of a vibration unit to fix the vibration unit in the pressing channel. The convex section has a concave surface facing an inner side wall of the insertion cavity, with a curved interval formed between the concave surface and the inner side wall. An elastic rubber block is filled in the curved interval and the elastic rubber block abuts against the inner side wall.

An oral care implement handle or a refill head therefor. The refill head may include a sleeve portion extending from a proximal end to a distal end, the sleeve portion having an inner surface that defines an internal cavity. The internal cavity may extend along a sleeve axis from an open bottom end at the proximal end of the sleeve portion to a closed top end, the internal cavity being configured to receive an attachment portion of a stem of an oral care implement handle. The internal cavity may have a proximal section adjacent the open bottom end and a distal section adjacent the closed top end. The distal section of the internal cavity may include a central portion located on the sleeve axis and at least one slot portion radially extending from the central portion.
