This is an educational tool. It does not diagnose anything, it is not medical or dental advice, and it does not create a doctor–patient relationship. It cannot tell you what you have — only what a thorough workup usually includes and which parts of it your answers suggest have not been done yet. Take this to a clinician. Do not use it to rule anything out.

Built by Shane Cope, DDS, MSD — residency-trained in periodontics (Indiana University School of Dentistry) and in oral medicine and orofacial pain (University of Southern California). The dryness questions use the Xerostomia Inventory (XI-11), a published research instrument. Symptom-timing patterns follow the classification described by Lamey and colleagues.
