Abstract: A toothbrush is disclosed. The toothbrush includes a handle, a brush tip coupled to the handle, the brush tip including a plurality of bristles, a motor housed within the handle for operating the brush tip, a power source coupled to the motor, one or more lights coupled to the handle and viewable by a user when holding the handle, and a control module housed within the handle and in communication with the one or more lights, wherein the control module is configured to monitor a pressure exerted by the brush tip on a surface, determine when the exerted pressure exceeds a pressure threshold, and, in response to the exerted pressure exceeding the pressure threshold, activate the one or more lights to alert the user that the exerted pressure exceeds the pressure threshold.

Abstract: A toothbrush is disclosed. The toothbrush includes a handle, a brush tip connected to the handle, wherein the brush tip includes a plurality of bristles operably connected thereto, a power source, a direct current motor in selective electrical communication with the power source, wherein the motor includes a drive shaft, a drive assembly connected between the brush tip and the drive shaft, wherein the drive assembly converts rotation of the drive shaft into movement of the plurality of bristles, and a control assembly in electrical communication with the motor and the power source; wherein during operation of the motor, the control assembly monitors a current draw by the motor and adjusts a current applied to the direct current motor based on the current draw.
