Smart toothbrush that tracks and removes dental plaque

A toothbrush for removing dental plaque, the toothbrush comprising:

• a first set of light-guiding bristles, the first set having one or more light sources therein, and a second set of light-guiding bristles, the second set having one or more optical sensors therein;
• one or more processors, one or more computer-readable memories, and one or more computer-readable storage media;
• and
• program instructions, stored on at least one of the one or more computer-readable storage media for execution by at least one of the one or more processors via at least one of the one or more computer-readable memories to:
• capture tooth data based on a difference between light emitted from the one or more light sensors of the first set of light-guiding bristles towards a tooth of a user and light reflected off the tooth of the user captured through the one or more optical sensors of the second set of the light-guiding bristles;
• collect tooth brushing data for the user from a dental history or a brushing history;
• extract one or more features from the tooth data and the tooth brushing data for the user;
• determine a plaque value using a machine learning model that weights the plaque value based on the one or more features, wherein a higher absorption level of the emitted light is associated with a higher plaque value;
• and
• identify a dental plaque location on the tooth based on the plaque value.
