How to clean the black bottom of the toothbrush

The toothbrush handle may have become moldy in a humid environment. It is best to boil it in boiling water before use. If it cannot be cleaned, you should replace it with a new toothbrush.

As long as the toothbrush is used for a period of time, a large number of bacteria will grow and multiply, including Candida albicans, hemolytic Streptococcus, Pneumococcus, etc. These bacteria can directly invade the human digestive tract and respiratory tract through the mouth, which may cause enteritis and lung infections. At the same time, if they enter the human blood through damaged oral mucosa, they will cause serious blood diseases. Therefore, after using a toothbrush, in addition to keeping the toothbrush dry as much as possible, it is best to expose the toothbrush to the sun for disinfection frequently. The place where toothbrushes and toothpaste are usually stored should be ventilated and dry, otherwise bacteria and other microorganisms that are harmful to health will breed. The frequency of replacing toothbrushes should be between one to two months.

How often should you change your toothbrush?

Toothbrushes are something we use every day, and they are used very frequently. Many people only realize that they need to change their toothbrushes after they become deformed. In fact, this is a very bad habit. So, how often should we change our toothbrushes?

Generally speaking, the bristles of toothbrushes currently sold on the market become bent after 1-3 months of use.

Studies have confirmed that under normal use by ordinary people, a three-month-old toothbrush can still function well and is just as effective as a new toothbrush in removing plaque. However, if you use it improperly or with too much force, the toothbrush may quickly lose its ideal cleaning ability, and the soft bristles make it more difficult to clean out food debris stuck between teeth.

Moreover, after the toothbrush head is deformed, people will habitually brush their teeth more vigorously, and vigorous brushing can easily abrade the gums and damage the tissues. In addition, bacteria are likely to remain in the toothbrush head if it is used for too long, so it is generally recommended to replace the toothbrush no more than three months.

It should be noted that the toothbrush should be replaced every three months. If you use the toothbrush improperly or use it too frequently, you should replace the toothbrush more frequently. In other words, the replacement of a toothbrush should be determined based on the actual situation, such as the deformation of the toothbrush bristles and the frequency of brushing. It is generally recommended that you judge whether the toothbrush needs to be replaced by observing the bristles.
