Disclosed is a vibration apparatus for dental care including a body in which a vibrator is embedded; a tip part connected to the body to extend to an outside of the body and configured to transmit vibration energy of the vibrator to a resin applied to a tooth; and a controller configured to control a magnitude of vibration energy generated from the vibrator and transmitted to the tip part, wherein the controller controls a vibration frequency of the tip part within a range of 3 to 70 Hz. According to such configuration, the viscosity of resin attached to a tooth is lowered so that the resin can be easily formed into a desired shape and the tooth can be treated without generation of voids in the resin.
