A system for providing a health profile of an individual, comprising: a toothbrush comprising data outputting means, wherein the toothbrush has a tooth cleaning element and a sensor, wherein the data outputting means comprises means for outputting data from the sensor, and wherein the sensor is a diagnostic sensor; a computing unit configured to derive a health profile of an individual using data obtained from the data outputting means of the toothbrush; and a display configured to display a representation of the health profile, wherein the representation of the health profile comprises an indication of whether the individual is suspected of having a health aspect such as one or more of gingivitis, periodontal gum disease, plaque, halitosis and heart disease, based on the data obtained; characterised in that the representation of the health profile includes a graphical depiction of an oral cavity divided into a plurality of different regions (501, 502, 503, 504, 505), wherein the plurality of different regions (501, 502, 503, 504, 505) comprise an upper teeth region and a lower teeth region, and wherein selection of one of the health aspects causes the representation of the health profile to provide an indication of which of the plurality of different regions (501, 502, 503, 504, 505) of the oral cavity is affected by the selected health aspect; and in that the toothbrush comprises a position sensor operable to detect a position or an orientation of the toothbrush so as to indicate whether the toothbrush is being held bristle-side up or bristle-side down; wherein the data outputting means comprises means for outputting data from the position sensor; and wherein the indication of which of the plurality of different regions (501, 502, 503, 504, 505) of the oral cavity which comprise an upper teeth region and a lower teeth region is affected by the health aspect is obtained from the data originally generated by the position sensor which indicate whether the toothbrush is being held bristle-side up or bristle-side down. a toothbrush comprising data outputting means, wherein the toothbrush has a tooth cleaning element and a sensor, wherein the data outputting means comprises means for outputting data from the sensor, and wherein the sensor is a diagnostic sensor; a computing unit configured to derive a health profile of an individual using data obtained from the data outputting means of the toothbrush; and a display configured to display a representation of the health profile, wherein the representation of the health profile comprises an indication of whether the individual is suspected of having a health aspect such as one or more of gingivitis, periodontal gum disease, plaque, halitosis and heart disease, based on the data obtained; characterised in that the representation of the health profile includes a graphical depiction of an oral cavity divided into a plurality of different regions (501, 502, 503, 504, 505), wherein the plurality of different regions (501, 502, 503, 504, 505) comprise an upper teeth region and a lower teeth region, and wherein selection of one of the health aspects causes the representation of the health profile to provide an indication of which of the plurality of different regions (501, 502, 503, 504, 505) of the oral cavity is affected by the selected health aspect; and in that the toothbrush comprises a position sensor operable to detect a position or an orientation of the toothbrush so as to indicate whether the toothbrush is being held bristle-side up or bristle-side down; wherein the data outputting means comprises means for outputting data from the position sensor; and wherein the indication of which of the plurality of different regions (501, 502, 503, 504, 505) of the oral cavity which comprise an upper teeth region and a lower teeth region is affected by the health aspect is obtained from the data originally generated by the position sensor which indicate whether the toothbrush is being held bristle-side up or bristle-side down.
