Rotating dental systems and related guards and methods are disclosed. In some instances a guard may be configured to prevent material from building up on at least a portion of the dental system. The guard may be configured to prevent materials from being discharged from the dental system. In some embodiments, the guard may also be configured to direct the flow of material along a portion of the dental system. Some guards within the scope of this disclosure comprise bristles.

A toothbrush system configured to be coupled to an external suction source. The toothbrush system includes a shaft with a main body with a first end and a second end, and a bristle array and a suction port arranged at the second end. The bristle array and the suction port both extend away from the shaft so that an opening of the suction port is proximal to a distal end of the bristle array. The shaft also includes a stem arranged at the first end. The stem includes a passageway that extends through the main body to provide a fluid connection to the suction port, and is configured to be coupled to the external suction source. Also, the handle is removably coupled to the shaft and includes a drive system operably coupled to the bristle array to actuate motion of the bristle array.

The present invention discloses a toothbrush head and an electric toothbrush, wherein the toothbrush head is connected to the drive shaft of the toothbrush handle, and comprises a toothbrush head and a clamping piece. The toothbrush head comprises a brush end and a connecting end that are opposite to each other. The clamping piece is installed on the connecting end, and provided with an elastic arm and a clamping slot for clamping the drive shaft. One end of the elastic arm close to the brush end is a free end, and some part of the sidewall of the clamping slot is formed by the elastic arm. The elastic arm is further provided with a butting boss. The butting boss protrudes from the elastic arm into the clamping slot, and can be elastically butted with the drive shaft. The toothbrush head provided by the prevent invention can solve the technical problem that the toothbrush head on some existing electric toothbrushes is difficult to detach from the toothbrush handle.

A brush head (32) including: a supporting portion (42) of a brush neck (40); a plurality of bristle tufts (21), each of which comprises a plurality of bristle strands having a proximal end (23) and a free end (25), wherein each of the plurality of bristle tufts comprises a proximal end head portion (26) melted into a first shape within a mold; and an elastomeric matrix (30) comprising at least a portion of the hard brush neck and the proximal end head portions, wherein the first shape of the proximal end head portion is configured to engage the elastomeric matrix such that the bristle tufts are retained within the elastomeric matrix.

A replaceable head for removeable connection with a manual toothbrush handle, the head comprising: a first end, a second end opposite to the first end, a neck having a hollow portion therein and extending between the first end and the second end, and a bristle carrier disposed adjacent to the first end. The second end comprises a second-end opening leading into the hollow portion of the neck and terminates with a second-end edge comprising a chamfered surface structured and configured to mate with a corresponding chamfered surface of the handle when the head is connected thereto. The neck's hollow portion is defined by an inner wall comprising a recess for receiving a spring-loaded ball associated with a connector of the handle.

An oral cleansing device (e.g., an irrigating, electric toothbrush) is disclosed. The oral cleansing device includes a handle, a cleansing attachment (e.g., a brush head attachment), and an irrigating attachment (e.g., an oral irrigator tip). The handle includes one or more control buttons to activate motion of an output shaft and/or an irrigating feature of the oral cleansing device. The cleansing attachment includes a plurality of bristles and is attachable to the handle such that movement of the output shaft is transferred to the cleansing attachment. The irrigating attachment defines an internal fluid passageway for receiving fluid from the handle and is attachable to the handle such that movement of the output shaft is not transferred to the irrigating attachment.

Disclosed is an electric toothbrush including a head and a handle having a shape couplable to the head and configured to supply a driving voltage to the head according to a user's control. The head includes a toothbrush head in which bristles and first and second electrodes spaced apart from each other are disposed, a head body extending from the toothbrush head, first and second connection lines disposed in the head body and connected from the toothbrush head to the first and second electrodes respectively, a head cover configured to close an end of the head body, and first and second connection pins respectively connected to the first and second connection lines and having portions externally exposed through the head cover.

A brush device for an ultrasonic scaler includes: a base having a first end and an opposite second end, the first end and the second end define a longitudinal axis of the base; an insert housing extending from the first end of the base, the insert housing defines an opening sized and shaped to receive a distal end of the ultrasonic scaler and secure the brush device thereto; and a cleaning element extending from the second end of the base, the cleaning element is substantially parallel to the longitudinal axis.

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 housing including a first housing portion having an inner surface that defines a first cavity and a second housing portion having an inner surface that defines a second cavity. The tracking attachment may also include a tracking unit configured to facilitate tracking at least one of a position, orientation, or movement of the oral care implement to which it is attached. A first portion of the handle may be positioned within the first cavity and a second portion of the handle may be positioned within the second cavity.
