A removable and transferable electronic system monitors the brushing patterns and brushing intensity of a user by analyzing the sound(s) that is produced by a conventional tooth brush as it passes over the teeth and/or gums. The system couples to the toothbrush and the brushing sounds are captured by a microphone coupled to the toothbrush which is then communicated to a microprocessor coupled to a digital display. After the microprocessor has analyzed the brushing sounds, a message is displayed on the digital display that directs the user to continue brushing or change brushing habits, depending on the outcome of the analysis. After brushing, the system may be decoupled from the toothbrush and stored or coupled to another user's toothbrush and the process repeated.
