The Importance of Toothbrush for Oral Health

Toothbrush is a tool to clean the mouth, but many people neglect the hygiene of toothbrush. For example, the bristles of the toothbrush are bifurcated and still not replaced. The toothbrushes of the whole family are put together, and the bristles are rubbed with each other or shared with the mouthwash cup, resulting in the indirect transmission of bacteria; or the bristles are placed downward, resulting in the failure of the bristles to keep dry and easy to breed bacteria. I suggest that you should keep your toothbrush dry at ordinary times and change it regularly every 3 months to ensure your health.

Oral cavity and teeth are one of the main portals for bacteria to invade the human body. Toothbrush contacts teeth and oral cavity every day, inevitably many bacteria are hidden in the gaps of toothbrush; in addition, toothbrush often remains toothpaste and sucrose on toothpaste, which also provides good conditions for the growth and reproduction of bacteria. Therefore, if the toothbrush is not cleaned or replaced regularly, it will pose a threat to human health.

Once upon a time, a stomatologist used a cold light instrument to detect the water just after cleaning the dishcloth, and found that there were more than 70000 bacteria in the water. However, after two days of bacterial culture, the number of bacteria on the brush hairs was more than 690000, almost 10 times that of the dishcloth water.

These bacteria, including Staphylococcus, Streptococcus, Candida, etc., mainly exist in the oral cavity, a few in the environment, originally safe with the human body, but if the bacteria invade the human body from the oral wound and gum bleeding, it will cause acute tonsillitis Pharyngitis and other diseases, if the immune system is not sound, easily lead to rheumatic fever, acute glomerulonephritis, endocarditis or septicemia.

It is the first step of oral hygiene to form a good habit of maintaining toothbrush. Remind people to form the habit of washing teeth after brushing teeth. Keep the place where the toothbrush is placed dry. If you have to put it in the bathroom, you’d better open a window to keep the bathroom ventilated. When placing the toothbrush, keep the brush head up, not down, so as to avoid increasing the chance of getting infected with bacteria.

As for when to change the toothbrush? Depending on personal use, if you brush twice a day, you need to change your toothbrush about 3 months; if you brush three times a day, you need to change your toothbrush at a shorter interval.
