Is a regular toothbrush or an electric toothbrush better?
Dec 02,2025
In terms of toothbrush selection, it is recommended to choose a toothbrush with small soft bristles. The size of the brush head and the softness of the bristles are also carefully considered. It is usually better for the toothbrush head to cover the tooth surfaces of both front teeth. We can choose according to age in the supermarket. Brush heads for 0-2 years old are about 15 millimeters long, brush heads for 2-6 years old are about 19 millimeters long, brush heads for 6-12 years old are about 22 millimeters long, and brush heads for 12 years old and above are about 25 millimeters long.
The brush head should not be too long, otherwise it will be difficult to clean the back half of the mouth. The width should not exceed four rows of bristles, and the top of the brush head should be elliptical, which is convenient to operate; The material of the bristles should be soft and fine nylon thread, with a polished surface at the top that is wear-resistant and easy to dry. The softness and hardness of the bristles should be moderate, as being too hard can damage the dental tissue, while being too soft makes it difficult to clean thoroughly. The handle of a toothbrush should be comfortable to hold, elastic, and slip resistant.
After prolonged use, the bristles of the toothbrush may become deformed, bent, and other issues. When using a toothbrush, the bristles should be as close to the tooth surface as possible to clean the plaque on each tooth surface. If the gap between the bristles widens, it will weaken the cleaning effect of the toothbrush, causing toothpaste or food residue, soft dirt, etc. to accumulate at the roots of the bristles. When the residue slowly accumulates at the bottom of the toothbrush and cannot be completely removed, it can cause a large number of bacteria to proliferate, affecting oral health.
When the bristles of the toothbrush bend, deform, or collapse, it indicates that the toothbrush has been worn out, and we need to replace the toothbrush in a timely manner.
Long term use of toothbrushes without replacement can result in a large amount of bacteria on the surface of the toothbrush. Even if the toothbrush is dried, bacteria still exist, which is not beneficial for oral health. Bacteria can erode the mouth and easily lead to oral diseases such as periodontitis.
