Devices, methods, systems, and computer program products for quantifying the amount of pressure exerted on a tooth or a set of teeth by an aligner. The quantification may be facilitated by a sensor disposed in the aligner and the sensor may be configured to generate an output signal signifying the amount of pressure in response to receiving an input signal. The input signal may be generated by a detection instrument or a computing device. The amount of pressure may be stored in a treatment tracking software and/or treatment tracking database for review and consideration by a treatment professional. The treatment professional may thereafter make decisions about the orthodontic treatment based on quantified amount of pressure on the tooth or set of teeth.
