Toothbrush is an indispensable oral hygiene tool in our daily life, but not everyone knows about the maintenance of toothbrush. Some people do not change their toothbrush after several years. Some people put their toothbrush in a sealed toothbrush box after brushing their teeth. Even two or three people share a toothbrush. These methods of using toothbrush can not only clean the mouth, but also become the source of oral bacteria.
The correct method of toothbrush maintenance is as follows:
After brushing your teeth, wash them thoroughly with clean water, not only remove the remaining toothpaste and food debris from the toothbrush, but also dry the water on the toothbrush as far as possible. Put the head of the toothbrush up into the mouthwash cup and place it in a dry and ventilated place. Because wet toothbrushes breed bacteria easily. Some scholars have found that whether healthy people or patients use toothbrushes, after a month, there are a large number of bacteria on the toothbrush reproduction. Impurity toothbrushes not only cause gingival inflammation, but also are the source of many diseases.
Toothbrushes are mostly made of nylon filaments, which are easily deformed by heat. Therefore, toothbrushes can not be washed in high temperature water, let alone disinfected by boiling method. A toothbrush can not be used for a long time. It is usually replaced quarterly, or it should be replaced in time when the curl and bifurcation of the bristles are found, so as not to brush the gums.
We should adhere to the principle of one person, one toothbrush, so as to avoid the cross-transmission of infectious diseases.
