How long have you been using your toothbrush? Are the bristles of your toothbrush crooked? I'm telling you quietly that if you don't replace your toothbrush regularly, the consequences can be serious!

Under what circumstances should a toothbrush be replaced?

1. The color of the toothbrush roots darkens: The dirt at the roots of the bristles gradually accumulates, which is one of the reasons for the growth of bacteria. Even cleaning after each use cannot completely prevent it, so once the color at the base of the toothbrush becomes darker, it should be replaced immediately.

2. The distance between bristles increases: Normal toothbrush bristles should be densely arranged. If the distance between bristles becomes significantly wider, dirt will be more likely to remain at the roots of the toothbrush. At this point, it is necessary to replace the toothbrush.

3. Outward or deformed bristles: Prolonged use of bristles can easily cause them to wear out and stretch out, making it difficult to fit the tooth surface and reducing the cleaning effect of the bristles. Under long-term stress, the distance between bristles is prone to widening and irregular branching, which not only leaves dirt but also scratches gums and wears teeth.

4. When using for too long: Generally, we need to replace toothbrushes every three months. But if the brush head is placed in a damp environment like the bathroom for a long time, it is very easy for bacteria to breed. After using a toothbrush for two weeks, bacteria will adhere to the brush head

The quantity can reach 2 million. So the scientific method is to replace the toothbrush within three months.

How to choose a toothbrush?

1. Choosing the appropriate brush head: If the toothbrush brush head is too large, it will not be able to rotate freely in the mouth during use, and the gaps will not be cleaned. Gradually, dental plaque will accumulate, which will eventually lead to the formation of tartar and eventually cause diseases such as dental caries and periodontitis. Therefore, it is necessary to choose a toothbrush head of appropriate size.

2. Choose bristles with moderate softness and hardness: If the bristles of a toothbrush are made of hard materials, they can cause damage to the gums, long-term damage to enamel, and gum bleeding. A toothbrush that is too soft cannot clean every corner of the mouth, so when choosing a toothbrush, it is important to choose one with moderate softness and hardness. Patients with periodontal disease and periodontitis can choose a softer toothbrush.

3. Choose a toothbrush with bristles that are rounded at the top: When choosing a toothbrush, you may find that the bristles are also very different at the top, some are rounded and some are pointed. If the top is not rounded, the long bristles will easily reach deep into the gaps between teeth, and if not careful, it may damage the gums and cause tooth sensitivity! Therefore, when choosing a toothbrush, try to choose a toothbrush with rounded bristles at the top.
