What happens if you use someone else's toothbrush

Toothbrushes are mainly used to clean the oral cavity. Regular brushing can make our teeth look bright and white. Because toothbrushes are used directly in the mouth, they are very personal items. In daily life, we don’t allow others to use our toothbrushes. The problem is that sometimes mistakes may occur, resulting in the toothbrush being shared with others. So, what happens if you use someone else’s toothbrush? Let’s look at the consequences.

Can I use someone else's toothbrush? There are many dangers of using a toothbrush incorrectly. The most important thing to note is that it can lead to the spread of diseases, such as hepatitis B, AIDS, tuberculosis and other infectious diseases. Therefore, the key is to see whether the other person has an infectious disease. Another possibility is that if the oral mucosa is damaged or there is bleeding gums, the possibility of mutual infection is very high. If you are a healthy person, then don't worry too much. At the same time, you need to keep your personal belongings in a place you are familiar with and pay attention to personal hygiene.

So you can't share a toothbrush with two people.

The correct way to use a toothbrush: 1. Wash the toothbrush thoroughly after each use and shake off as much water as possible. Place the toothbrush head upward in a mouthwash cup, or place it in a ventilated and sunny place to dry it and sterilize it.

2. If conditions permit, you can buy 2 or 3 toothbrushes and use them in rotation to extend the drying time of the toothbrushes. Doing this is especially important for people with gingivitis and periodontitis. In addition, rotating the toothbrush can also maintain the elasticity of the bristles.

3. Old toothbrushes whose bristles have spread out or curled and lost their elasticity must be replaced in time, otherwise it will be harmful to the teeth and gums.

4. Children living in a group should have their toothbrushes thoroughly cleaned and disinfected once a week.

5. Toothbrushes should not be shared to prevent cross-infection of diseases.
