According to the dental hospital, in fact, ultrasonic whitening refers to ultrasonic cleaning, which can only remove the calculus and pigment on the surface of the teeth, and cannot change the color of the teeth themselves. Many people think that after using ultrasonic cleaning, the teeth will become white, but in fact, the original color of the teeth is exposed, not the teeth are really white. Therefore, if you want to whiten your teeth and look beautiful, you still need to use the teeth whitening technology of the dental hospital.
