Innovative oral health monitoring technologies, which may be embodied in various apparatuses, systems, and methods, provide enhanced patient sample pH testing and other health data. The technologies may involve an oral health monitoring apparatus, which may include a mouthpiece housing, a pH sensor, and a wireless communication interface. The mouthpiece housing may be fitted to a mouth of a patient and may, by way of the pH sensor, capture saliva pH measurements. The technologies may involve wirelessly transmitting the measurements to a server for health condition correlation analyses, visual report generation, and subsequent display on a user device.
