Intelligent toothbrush monitoring device

A toothbrush monitoring device for a user using a toothbrush, comprising:

• a processor;
• an output device for providing feedback to the user;
• a sensor coupling with the toothbrush for measuring toothbrush patterns, the sensor consisting of an accelerometer such that the accelerometer produces data indicating inclination of the toothbrush;
• a recording device coupled with the processor and the sensor, the recording device being arranged such that reference data relating to a preferred toothbrush pattern is captured by the sensor and stored in the recording device for a plurality of teeth regions, when in a first mode, during use of the toothbrush by the user in the first mode for recording the reference data;
• and
• a comparator coupled with the output device, the processor, the sensor and the recording device such that the comparator compares in the recording device for each of the plurality of teeth regions the reference data to data measured by the sensor, during use of the toothbrush in a second mode, and the comparator indicates with the output device one or more of the plurality of the teeth regions not brushed according to the reference data relating to the preferred toothbrush pattern.
