Automatic toothbrushes
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.
1. A method of manufacturing an assembly for a toothbrush, the method comprising:
forming a body having a first side and second side, wherein the body has a generally planar shape including a trough portion and wall portions extending from the trough portion, and wherein the body includes an engagement feature on the second side on one side of the wall portions, and further wherein the engagement feature is shaped and sized to be operably coupled to a motor of the toothbrush;
coupling a plurality of bristles to the first side of the body; and
bending the wall portions relative to the trough portion to define a channel, wherein the bristles extend at least partially into the channel, wherein the trough portion has a U-like shape, and wherein the channel is sized to be positioned over most of the lower or upper teeth of a user.
2. The method of claim 1 wherein at least one of the bristles has a different length than another one of the bristles.
3. The method of claim 1 wherein, after coupling the bristles to the body, at least one of the bristles has a different angle relative to the body than another one of the bristles.
4. The method of claim 1 wherein bending the wall portions further includes heating the body.
