​Electric toothbrush brushes stones

An electric toothbrush is a type of toothbrush that is more popular among the public. It is more delicate than an ordinary toothbrush and it does not rely on human power at all. It relies on batteries and you can charge the toothbrush when it runs out of power. Dental tartar can be brushed away with an electric toothbrush, and it has certain efficacy and functions, but it also has certain side effects and sequelae. So, how to brush dental tartar with an electric toothbrush?

Dental calculus is a mineralized or mineralizing plaque and soft scale deposited on the surface of teeth or restorations. It is composed of 75% calcium phosphate, 15-25% water, organic matter, manganese phosphate, calcium mineral acid and trace amounts of potassium, sodium and iron. These calcium salts and other inorganic salts mainly come from saliva or gingival sulcus fluid and are yellow, brown or black in color.

Electric toothbrushes are new products that have appeared in recent years and have set off a revolution in the field of oral health abroad. Electric toothbrushes use the rapid rotation or vibration of the motor to produce high-frequency vibrations in the brush head, instantly breaking down the toothpaste into fine foam and deeply cleaning the gaps between teeth. At the same time, the vibration of the bristles can promote blood circulation in the mouth and have a massage effect on the gum tissue.

In principle, there are two types of electric toothbrushes: rotation and vibration. The principle of a rotary toothbrush is simple: an electric motor drives the round brush head to rotate, enhancing the friction effect while performing normal brushing movements. Rotary toothbrushes are noisy, clean the tooth surface very well, and are relatively weak in cleaning the gaps between teeth. However, they cause great wear on teeth and are not recommended for long-term use.

Vibrating toothbrushes are more complex and more high-end in price. A vibrating toothbrush has an electrically driven vibration motor inside that allows the brush head to produce high-frequency swings perpendicular to the direction of the brush handle, but the amplitude of the swing is very small, generally about 5 mm up and down. The largest swing amplitude in the industry is 6 mm.

When brushing your teeth, on the one hand, the high-frequency oscillating brush head can efficiently complete the action of brushing your teeth. On the other hand, the vibration of more than 30,000 times per minute also causes the mixture of toothpaste and water in the mouth to produce a large number of tiny bubbles. The pressure generated when the bubbles burst can penetrate deep into the teeth to clean dirt.
