 Eligible patients at the Craniofacial Pain Center at the Tufts School of Dental Medicine TUSDM will be randomized to listen to a tablet containing a calmative Comfort Talk app or app with white noise on an intent-to-treat basis. Their anxiety and pain measures will be recorded on validated 0-10 scales and before listening, at the end of the waiting room period, and every 10 minutes while on the dental chair.
