An intra-oral mouth vibrator preferably includes a lower bite pad, an upper bite pad, a retention pad, at least two vibratory motors and a power source. Two holes are formed through the upper bite pad to receive the two vibratory motors. One end of a wire is connected to the two vibratory motors to supply power thereto. The other end of the wire is connected to a power source. The retention pad preferably includes a perimeter retention lip. The upper bite pad is placed on a top of the lower bite pad. The upper and lower bite pads are inserted into the retention pad. In use, the vibratory motors receive electrical power from the power source, which causes the at least two vibratory motors to vibrate. The vibration causes the lower bite pad, the upper bite pad and the retention pad to vibrate.
