An electric toothbrush head and an electric toothbrush are provided. The electric toothbrush head includes a brush head body, bristles and a flexible member. The brush head body includes a brush rod and a brush plate. The brush plate is elastically deformable and has a non-deformed state and an elastically deformed state relative to the brush rod. An included angle between the brush plate and the brush rod is changeable within a range from 0 degrees to X degrees. The X degrees are equal to or greater than 10 degrees. The elastically deformed state includes a first deformed state in which the brush plate is bendable or deformable towards a front surface relative to the brush rod and a second deformed state in which the brush plate is bendable or deformable towards a back surface relative to the brush rod.

This disclosure presents systems and methods to improve user brushing behavior. Exemplary implementations may: effectuate presentation of audio content via an audio output device, the audio content being characterized by an audio profile; obtain output signals from one or more sensors coupled to a user device, the output signals conveying user input information, the user input information defining user input by a user via the user device; determine, based on the user input information, a user profile, the user profile including one or more user values of the one or more audio attribute; compare the user profile with the audio profile to determine, for individual audio attributes, one or more differences; determine one or more scores reflecting the one or more differences; and/or perform other operations.

The present disclosure generally relates to oral care systems and devices. An oral care system includes a container defining an interior portion and a moveable funnel configured to slide in the interior portion of the container. The moveable funnel includes a funnel portion having a base connected to a tube. The system further includes a toothbrush supported by the tube, the toothbrush having a handle extending out from the container.

An oral care implement including a handle and an oral care refill head. The handle has a gripping portion, an engagement component coupled to a distal end of the gripping portion, and a stem. The engagement component includes a plate portion and a first engagement feature. The stem extends through an opening in the engagement component and protrudes from the plate portion. The oral care refill head includes an oral care treatment portion and a sleeve portion. The sleeve portion has an inner surface that defines a sleeve cavity having a cavity axis and a second engagement feature. When the oral care refill head is detachably coupled to the handle, the first and second engagement features mate with one another to at least one of: (1) position the oral care refill head and the handle in an operational alignment; and (2) lock the oral care refill head to the handle.
