How To Choose Different Electric Toothbrushes

For different types of gums, different electric toothbrush performance should be selected.

Tooth enamel is the hardest substance in the human body, but long-term use will also cause some natural wear and even abrasion. Some people have good enamel development and are not prone to wear and abrasion; some people have poor enamel development, or tetracycline dental fluorosis, which is more prone to wear.

Teeth with enamel abrasion will be more sensitive, and symptoms of dentine hypersensitivity and even pain will appear when encountering hot and cold sour and sweet.

According to different tooth sensitivity, the performance of electric toothbrush should be measured when purchasing:

(1) Bristle rounding rate

Too sharp bristles are easy to damage the gums. People with thin gums/sensitive gums are recommended to use an electric toothbrush with a high rounding rate.

The bristles of the current electric toothbrushes use nylon filament bristles, and the tips of the bristles need to be rounded. The better the brand of electric toothbrushes, the higher the rounding of the bristles, the more comfortable to use; and the bristles with low rounding rate are similar to "bad hotel toothbrushes". , Sometimes I brush my gums and make my mouth full of bleeding.

Similarly, the rounding rate of the bristles is low, the bristles are sharper, and they are more likely to wear teeth, and those who are sensitive to the teeth themselves are more likely to wear teeth.

(2) Softness and hardness of bristles

The harder the bristles, the stronger the ``brushing power'', the better the cleaning effect, but improper use can easily damage the teeth and gums; the softer the bristles, the more friendly to the gums, and many ``postoperative care toothbrushes'' are particularly soft to prevent gums from touching the surgical area. pain. However, because this kind of toothbrush does not have enough cleansing efficiency, the soft bristles cannot completely brush off the plaque on the tooth surface. It is only recommended for short-term use after surgery.

For ordinary toothbrushes, we recommend soft bristles; but most of the electric toothbrushes on the market have medium-hard bristles and hard bristles. Why?

Because the vibration frequency of electric toothbrushes is fast, the bristles that are too soft are not easy to quickly recover their deformation under high-frequency vibration, and the cleaning efficiency is not enough. Therefore, the electric tooth actuator requires the bristles to have slightly higher hardness and strong elasticity. Therefore, for ordinary people, an electric toothbrush with medium hard bristles is fine, and for people with sensitive gums, there are still soft electric toothbrushes on the market to choose from.

(3) Brush head and vibration method

Electric toothbrushes on the market are mainly divided into two brush heads and matching vibration methods. One is a square brush head similar to ordinary toothbrushes. The matching vibration method is vibration along the long axis of the toothbrush (simulated Pap brushing method, horizontal vibration cleaning Gingival sulcus), or vibration perpendicular to the long axis of the toothbrush (simulating vertical brush method, vertical vibration to clean the gap between teeth). The amplitude and vibration of this brush head are smaller, and it is more acceptable for people with sensitive gums.

The brush head of another electric toothbrush is a circular brush head, and the matching vibration mode is compound vibration, that is, vertical tooth vibration + reciprocating rotation mode. Because the vibration method is complex, the amplitude and vibration feeling will be larger than the square brush head, but the cleaning efficiency and cleaning ability are also stronger. If people with sensitive gums use this electric toothbrush, it is recommended to choose a soft round brush head.
