Have you ever paid attention to your toothbrush? How long have you been using your toothbrush? Toothbrush is an important tool for protecting oral health, but many people do not pay enough attention to the protection and use time of toothbrushes. Sometimes, the bristles have mostly fallen or fallen off, but they are still in use, which can easily cause damage to the oral cavity. Therefore, everyone should also have a certain understanding of the hygiene knowledge of toothbrushes in order to create a healthy oral environment.

After each use of the toothbrush, rinse it thoroughly and shake off as much water as possible. Place the toothbrush head facing up in the mouthwash cup and be sure to keep it in a well ventilated and sunny place away from the sink and toilet, allowing it to dry and receive sunlight for sterilization.

You can use 2-3 toothbrushes alternately to extend the drying time of the toothbrushes. This is particularly important for people suffering from gingivitis and periodontitis. Rotating use can also maintain the elasticity of toothbrush bristles.

The toothbrushes currently available on the market have bent bristles after 2-3 months of use. Curved toothbrush bristles not only make it difficult to clean food residue between teeth, but also scratch the gums. In addition, toothbrushes that have been used for too long are prone to bacterial retention in their heads. So it is generally recommended to replace the toothbrush every 2-3 months. But people who brush their teeth three times a day or prefer to brush their teeth with warm water will experience faster bristle wear and should change their toothbrush once a month.

If you have had a cold or other infectious disease, it is best to replace your toothbrush with a new one after recovering from the illness. Before using a new toothbrush, it should be blanched in hot water to soften the bristles and kill bacteria.

In addition, family members do not put toothbrushes together, but instead place multiple dental jars, which is more conducive to the prevention and control of infectious diseases.
