Can the toothbrush be used all the time? When should a toothbrush be replaced?

Brushing your teeth once a day and before going to bed can remove food debris from your mouth, which not only prevents bad breath, but also reduces the risk of oral diseases. The ancients said: If a worker wants to do a good job, he must first sharpen his tools. In order to prevent oral diseases, in addition to mastering the correct brushing method, we must have a good toothbrush. What are the signs that it's time to change your toothbrush? 1. The bristle tips are soft and collapsed. Most of the bristle tips are soft and collapsed, indicating that the toothbrush is relatively worn and cannot clean the teeth better. 2. The color of the root of the toothbrush is darkened. The color of the root of the toothbrush is darkened, indicating that too much dirt has accumulated, which is the result of a large number of bacteria breeding. Careful cleaning after using the toothbrush cannot prevent it, so it should be replaced with a new toothbrush in time. 3. The distance between the bristles is widened. The new bristles are densely arranged, and the widening of the distance between the bristles will easily cause dirt to remain at the root of the toothbrush. In this case, a new toothbrush should be replaced. How to choose a toothbrush that suits you? 1. The brush head is short and narrow. Choose a toothbrush with a short and narrow brush head, which can rotate freely in the mouth and ensure that every aspect of the teeth can be brushed to the greatest extent. 2. The bristles are moderately soft and hard. The softer the bristles are not the better. The bristles are too soft to grasp the strength, and they cannot better remove food residues and bacteria in the mouth. Too much brushing can damage the gums and shorten the service life of the toothbrush. . Although hard-bristled toothbrushes have good cleaning power, they are easy to cause tooth wear and damage, so you should choose moderately soft and hard bristles. 3. The bristle tip is processed. After the bristles of the toothbrush are cut, they are not smoothed, and the gums are often damaged because they are too sharp. Therefore, you should choose a toothbrush that has been smoothed to better protect the gums. 4. A good toothbrush should have 2 to 4 rows of bristles, and each row has 5 to 12 bundles. This toothbrush can better remove plaque, and the toothbrush is easier to clean. 5. The brush handle has a non-slip design to ensure that the toothbrush handle is more convenient and comfortable to hold, and has a non-slip design; the toothbrush handle needs to match the shape of the hand. So far, there are two types of toothbrush handles on the market, one is a straight type, which is not easy to grasp the strength; the other is an angled type, which is easy to clean the plaque. Make sure that the angle between the toothbrush handle and the brush head is about 17-20 degrees. Warm reminder even if the toothbrush does not have the above problems, it is necessary to change a new toothbrush every 3 to 4 months, especially those with low immunity should increase the frequency of toothbrush replacement, which can reduce the risk of infection. The correct method is: rinse the toothbrush with running water several times after brushing, shake off the moisture in the toothbrush, and then put it in a dry and ventilated place or face the toothbrush head. Put it on the toothbrush bowl to avoid mold growth. Family doctor's online feature, may not be reproduced without authorization
