An oral care appliance configured for investigation of a user's mouth, comprising:

• a source of light (16) having a wavelength suitable for oral health condition diagnosis and/or treatment;
• an assembly (16, 14, 26) configured for directing the light to the dental region of the mouth, illuminating one or more teeth;
• a light receiver or camera and sensor assembly (16) configured for receiving light reflected from the teeth, the sensor assembly providing output signal information corresponding to the reflected light from said one or more teeth;
• a processor (20) configured for identifying the presence of an oral health condition from the output signal information;
• a memory configured for storing known typical size and location information of teeth in the mouth, wherein the processor is programmed for processing the stored size and location information with the output signal information, to determine those teeth which have been investigated and the location of oral health conditions and/or to identify those areas of the teeth which have not yet been investigated and to provide such information to a display;
• a system (16) configured for treating the identified oral health condition;
• and
• a display (24) configured for providing to the user information concerning any oral health conditions which have been identified by the processor and information concerning those areas of the teeth which have and/or have not been investigated.
