A mouth-containing toothbrush includes a housing, a first tooth-brushing module assembly and a rotary drive assembly. The housing has a groove for containing teeth. The groove has a first inner groove face, a second inner groove face, and a bottom face connected between the first inner groove face and the second inner groove face. The first tooth-brushing component is used for cleaning surfaces of the teeth, and the first tooth-brushing component includes a brush body shaft and bristles arranged on an outer circumference of the brush body shaft. The brush body shaft is rotatably arranged between at least one of the first inner groove face and the second inner groove face and the teeth, and the brush body shaft extends along an extension direction of the groove. The rotary drive assembly is used to drive rotation of the brush body shaft.

The amplitude control assembly for an oral care appliance includes a capacitance-sensing touch array (26) responsive to the position of a user's touch thereon to change the value of capacitance from the array, as determined by a sensor (30). A control assembly (24), responsive to the change of capacitance, changes an operating characteristic of the drive signal for the appliance, to change the amplitude of motion of a workpiece portion of the oral care appliance.

An electric toothbrush is disclosed herein. The electric toothbrush may include an elongated body portion with opposed first and second ends and a longitudinal axis extending therebetween; a brush head section arrangeable toward the first end and including: a first bristle support member rotatable in a first direction, and a second bristle support member coupled to the first bristle support member and rotatable in a second direction about a centrally defined axis, the second direction being opposite the first direction; and a drive rod coupled to at least the first bristle support member and having an axis oriented so as to extend coincident with, or substantially parallel to, the longitudinal axis of the electric toothbrush, the drive rod being arranged to linearly move along the axis so as to rotate the first bristle support member in the first direction and rotate the second bristle support member in the second direction.

A toothbrush (10) includes a brush assembly (16) with at least three bristle arrangements (12), each having opposing inwardly-directed bristles (122, 124, 126) for simultaneously contacting facial and lingual surfaces (52, 54), and preferably also occlusal surfaces (56) of the teeth (50). Flexible linkages (14), interconnecting the bristle arrangements (12), maintain a relative spacing between the bristle arrangements (12) while allowing variation of an effective curvature of the brush assembly (16) such that the bristle arrangements (12) can ride along, and conform to a non-uniform curvature of, the arch of teeth. The toothbrush (TO) preferably also includes an actuation mechanism (22) for generating to-and-fro motion of the brush assembly (16) along the arch of teeth, most preferably combined with a more rapid small-amplitude oscillatory motion.

A teeth cleaning device for simultaneously cleaning multiple teeth, of a user includes a mouth insert for inserting into the mouth of the user, a plurality of cleaning structures attached to the mouth insert or integrally formed together with the mouth insert, a coupling element attached to the mouth insert; and a drive device. The drive device includes a vibration motor, which can be connected to the coupling element such that the vibration motor vibrates the mouth insert during the operation of the teeth cleaning device, and a cleaning program selection element for selecting a cleaning program that defines a vibration frequency of the vibration motor within a specified frequency range and/or a vibration amplitude of the vibration motor within a specified amplitude range. The disclosure further relates to a method for producing such a teeth cleaning device.

Automatic toothbrushes are disclosed herein. A toothbrush configured in accordance with embodiments of the present technology can include, for example, a handle and a mouthguard coupled to the handle. The mouthguard can be configured to be positioned within a mouth of a user over multiple teeth of the user. A brush assembly having a plurality of bristles can be removably positioned within the mouthguard for engaging and cleaning the teeth of the user. A motor can be disposed within or coupled to the handle and configured to articulate the brush assembly within the mouthguard.

A brush head for an electric toothbrush includes a support part supporting upper and lower lateral brush elements and transverse brush elements for the combined brushing of the inner, outer and occlusal surfaces of the upper and lower teeth, and an oscillating device intended to impart an oscillating movement to the support part. The support part is elastically deformable such that it can fit snugly against the upper and lower dental arches during brushing. The oscillating device includes a movable part on which the support part is mounted, and a drive shaft coupled to the movable part in order to move the movable part and the support part in an oscillating manner. The movable part extends between the upper lateral brush elements and the lower lateral brush elements.

A powered toothbrush includes a plurality of rows of bristle tufts that project through a perforated top shell of a hollow toothbrush head. Ends of individual bristles are held in buckets to form the tufts and the bristle ends opposite the bucketed ends are free (where the opposite ends contact the toothbrush user's teeth). The bucketed ends of the bristle tufts are captured within the internal space within the head but are not fixedly attached to any other toothbrush component or structure. This non-fixed attachment feature enables the bristle tufts to have multiple degrees of freedom (DoF) of motion with respect to the perforations in the top shell and can rotate, move axially, and tilt.

A powered brush has two different brushes for different purposes that are selectively vibrated for powered cleaning. The brushes may be a tooth brush and an interdental brush that are separately operated at different frequencies. One or more buttons or switches provide control signals to the powered brush to selectively actuate the different brushes. A controller connects a motor to a power source such as a battery based on the control signals. The controller may include a timer for actuating the selected brush for a given time period.

The various embodiments described herein include methods, devices, and systems for creating customized dental care. In one aspect, a method includes obtaining a dental model of a particular user's teeth and determining, based on the dental model of the particular user's teeth, a configuration for a set of cleaning elements to be included with the toothbrush device. The method further includes forming the toothbrush device for the particular user based on the dental model of the particular user's teeth, whereby the toothbrush device includes: (i) a cleaner body, personalized for the particular user based on the dental model of the particular user's teeth, that defines a cleaning cavity shaped for receiving the particular user's teeth, and (ii) the set of cleaning elements, integrally formed with the cleaner body, that contact and clean the particular user's teeth during application of the toothbrush device, whereby the cleaning elements have the determined configuration.
