To do this, a stream of water with concentrated soda is directed to the teeth, after which they become whiter. The advantage of this method of teeth whitening is that it does not affect the enamel and the risk of side effects is minimal.

Mechanical teeth whitening is performed with anesthesia in case of scratches and damages that are sensitive to pressure drop. The same result can be achieved using an ultrasonic scaler.

Also, along with the dark pigment of the teeth, useful minerals can also be removed, which leads to demineralization.
