Which Op lets the dental team stay in touch throughout the day. With the push of a button, hygienists and assistants can notify the dentist if the patient needs an exam, to be numbed, a check, and in Which Op the patient is located. The message will show up on any device Which receives text messages. This allows the dentist to view messages hands-free so they can be discreetly notified when they are currently in the middle of a procedure with another patient.
