The Significance Of Replacing The Toothbrush

Toothbrushes are an inseparable oral hygiene tool in our daily life, but not everyone understands the maintenance of toothbrushes. Some people do not change their toothbrushes after using them for several years. Some people put their toothbrushes in a closed toothbrush case after brushing their teeth. There are even two or three people sharing a toothbrush. These methods of using toothbrushes not only fail to clean the mouth, but also become a source of oral bacteria. The correct toothbrush maintenance method is as follows:

After brushing your teeth, rinse thoroughly with clean water, not only to wash away the toothpaste and food debris left on the toothbrush, but also to shake off the water on the toothbrush as much as possible, put the toothbrush head up in the mouthwash cup, and place it in a dry and ventilated place. Because damp toothbrushes tend to breed bacteria. Some scholars have found that whether it is a healthy person or a patient's toothbrush, after a month of use, a large number of bacteria multiply on the toothbrush. Dirty toothbrushes can not only cause gum inflammation, but also a source of infection for many diseases.

Most toothbrushes are made of nylon filaments, which are easily deformed by heat, so they cannot be washed in high-temperature water, nor can they be sterilized by boiling. A toothbrush cannot be used for a long time. Generally, it should be replaced every quarter, or it should be replaced in time when the bristles of the toothbrush are found to be curled and bifurcated, so as to avoid the bristles from hurting the gums.

It is necessary to adhere to the principle of one toothbrush per person to avoid cross-spreading of infectious diseases.
