Professional dentists recommend changing the toothbrush once a month, because a lot of dental bacteria have accumulated on the monthly brush, which is the scientific toothbrush replacement cycle.

How long should the toothbrush be replaced, the dentist will generally recommend that the toothbrush should not be used for more than 3 months, and the bristles of the toothbrush are bent and deformed, so they should be replaced in time, because the cleaning effect of the toothbrush with curved and deformed bristles is significantly reduced, and the following is how long the toothbrush should be replaced.

The distance between the bristles becomes larger

Usually the bristles are densely arranged between them, and if the distance between the bristles is significantly wider, dirt is more likely to remain at the root of the toothbrush, so it is best to replace it with a new one.

The toothbrush must be cleaned and dried with clean water after each brushing, and the brush head must be placed in a ventilated and dry place with the brush head facing up.

If the toothbrush is used for a long time, bacteria accumulate in the bristles, which is not good for the health of the mouth. Therefore, the bristles must be replaced, at least every 3 months.
