Abstract: Intraoral sensors and associated systems, devices, and methods are provided. In some embodiments, an intraoral sensor for sensing pH within an intraoral cavity of a subject includes a film composed of a biocompatible polymer and a pH-sensitive molecule. The pH-sensitive molecule can be configured to change in color based on a pH within a subject's intraoral cavity. The pH-sensitive molecule can be immobilized in the film. The intraoral sensor can also include an adhesive configured to couple the film to a surface of a dental appliance or a tooth of the subject.
