Load sensing for oral devices

A toothbrush comprising:

• a brush tip comprising a plurality of bristles operably coupled thereto;
• a motor that actuates movement of the brush tip, the plurality of bristles, or a combination thereof;
• a power source that provides current to the motor;
• a sensing module that detects a current provided to the motor;
• and
• a motor control coupled to the motor and the sensing module, wherein the motor control dynamically adjusts a provided current to the motor based on the detected current.

A method of operating a toothbrush comprising:

• determining an initial current provided to a motor driving a plurality of bristles on a brush tip wherein the initial current is determined prior to applying any pressure to the plurality of bristles;
• detecting, by a sensing module, a current provided to the motor, wherein the detected current is proportional to a pressure applied to the plurality of bristles and the detected current is determined relative to the initial current;
• determining, by a processor, whether the detected current exceeds a threshold current;
• and
• responsive to determining that the detected current exceeds the threshold current, providing an alert to a user responsive to determining that the detected current exceeds the threshold or dynamically adjusting one of a current or a voltage provided to the motor.
