Mistake #1: Brushing too hard Brushing with too much force can hurt your teeth and gums, causing mouth ulcers. In fact, it is not true that the more force you use, the more you can brush your teeth clean. If you brush your teeth in the wrong way, too much force can hurt your teeth. Correct method: the brushing force size varies from person to person, and there is no special quantitative standard. The brushing force should not be too light or too heavy, in order to brush the surface of the teeth is appropriate. About the equivalent of a finger to pick up a popsicle force is enough, use the power of the wrist to brush teeth rather than the power of the arm. Mistake 2: Brushing when you wake up 98% of Chinese people wake up early every day to brush their teeth and then eat breakfast. Some people say that this will be the toothpaste in the “effective dental ingredients” with breakfast eaten together, in fact, ordinary toothpaste can only play a role in cleaning teeth, and there is no so-called effective dental ingredients. In fact, brushing before meals is a wrong habit. The right way: 20 minutes after the meal and then brush your teeth. After getting up and rinsing your mouth with water, eating breakfast, brushing your teeth 20 minutes after meals is the healthiest, especially after drinking acidic beverages or eating acidic foods. Mistake 3: toothbrush is too big Each person’s teeth have big and small, toothbrush is too big, in the mouth to perform the task will not be flexible enough, toothbrush is too small, and can not complete a large area of the mouth to clean the work. It is not recommended to use a toothbrush that is too big. The size of the toothbrush should be such that the head of the brush can flexibly reach the last teeth. If the toothbrush is too big, it will not be able to reach the teeth at the end of the mouth. Correct method: Choose a toothbrush of the right size, the size of the head should be equal to the width of 2 ½ to 3 teeth. When choosing a toothbrush, it is also important to see if the brush head can flexibly reach into the large teeth to clean them. Ordinary toothbrushes can be replaced every 3 months, but the bristles have been deformed toothbrush should be replaced immediately. Mistake 4: Cold water brushing teeth Cold water will lead to dentin sensitivity of people with sore teeth, and is not conducive to toothpaste within the effective substances of tooth cleaning role. Especially in winter, it is necessary to brush with warm water to avoid causing tooth sensitivity. The right way: The main ingredients in toothpaste are friction agents and fluoride, and laboratory research has found that the optimal temperature for these active ingredients to work is around 37°C. Therefore, when brushing, use water close to your own teeth. Therefore, brushing with warm water close to your own body temperature works best, and water that is too hot is not good. Mistake 5: horizontal brushing Survey shows that more than 90% of Chinese people use horizontal brushing method, which is a kind of physical wear and tear on the tooth enamel, dentists give the advice is vertical brushing. This is because brushing horizontally makes it difficult to reach the gaps between the teeth and does not achieve a thorough cleaning. Brushing horizontally has the worse effect of wearing down the enamel of the teeth, especially for those who brush harder, and over time “wedge-shaped wear” can easily form. Wedge-shaped wear is manifested by the roots of the teeth being worn down and atrophied, easy to make the teeth loose, sensitive. Correct method: The correct way to brush your teeth is to brush vertically along the gaps in your teeth.
