Needless to say, if you want to have a good white tooth, you should take good care of it. How often do you change your toothbrush?
How often do you change your toothbrush?
Toothbrush should not be used for more than 3-4 months. After using the toothbrush for 3-4 months, the bristles will be bent and deformed. If we continue to use it, not only the cleaning function will decline, but also the teeth and gums may be damaged.
Of course, according to the specific situation, some people use toothbrushes with greater loss than ordinary people. For example, people who brush their teeth very hard have a higher frequency of toothbrush replacement than ordinary people. Children also change their toothbrushes more often.
In addition to the service time, replace the toothbrush as soon as possible when the following three situations are found in daily use.
1 toothbrush bristles deformed
If the tip of the toothbrush is found to be deformed, it indicates that the degree of wear is large. The toothbrush has been difficult to bear the task of cleaning teeth and needs to be replaced.
2. The bristle spacing is too large
When I first bought it, the bristles were arranged in a regular dense arrangement. Once the bristle spacing is significantly widened, the effect of tooth cleaning will be reduced, and dirt is easy to remain at the root of the toothbrush, which is not conducive to oral health.
3. The color of bristle root becomes darker
With the increasing use of the toothbrush, the root of the bristle will accumulate more and more dirt, which is difficult to clean. Therefore, it is recommended to replace it in time once it is found.
The toothbrush should be replaced regularly. What points should be considered when choosing a toothbrush?
Brush head size
The brush head is large, the bristle area is large, and brushing teeth is more efficient, but it is difficult to clean some small corners of the mouth. The brush head is small and has high precision. It is easy to clean all parts of the oral cavity, but brushing teeth is more time-consuming.
The choice of brush head size mainly varies from person to person.
The bristles are soft and hard
It is recommended to choose soft hair, which is easy to go deep into the teeth and gingival sulcus, and the cleaning effect is better. However, you can't choose too soft bristles. Too soft will lead to poor cleaning effect.
Straight bending of brush handle
Whether the brush handle is straight or curved will not affect the brushing effect. If you choose to bend the brush handle straight, you can do it yourself.
