A device vibrates body tissue to reduce pain experience by the body tissue in a therapeutic procedure. The device includes a frame and a tip connectable to the frame which can be activated to produce vibration. An electromagnetic reader is connected to the frame and includes an antenna for sending and receiving electromagnetic radiation. An electromagnetic tag is connected to the removable tip, and also has an antenna for sending and receiving electromagnetic radiation in communication with the electromagnetic reader antenna. The antennas are disposed proximate to each other when the removable tip is connected to the frame, whereby the electromagnetic tag can transmit information to the electromagnetic reader.
