First, correct the wrong way of brushing your teeth. Brushing your teeth is also about methods, but many people don't master them. Many people find it convenient to brush their teeth sideways. The real way to brush your teeth is to brush it twice a day for at least 3 to 5 minutes each time, and brush it from top to bottom, so that you can continue to brush back and forth instead of brushing sideways, which is easy to hurt your gums. Brushing your teeth up and down may be unfamiliar at first, but you will feel particularly comfortable after you get used to it. Only in this way can the brush be clean and will not hurt the gums.
Secondly, eat less sweets and try not to drink carbonated drinks. Carbonated drinks contain acidic substances, and most of them contain pigments, and these acidic substances are easy to attach pigments to the surface of teeth, which will lead to yellowing and blackening of teeth after a long time.
Rinse your mouth in time after meals. Rinsing your mouth after a meal can reduce the food between your teeth. In the process of chewing, there will be a lot of food left in the teeth, and the fiber of these foods is harmful to the teeth and periodontal tissue, so it should be cleaned up in time, flossing can be used if necessary, and toothpicks can be used less, which will increase the gap between teeth.
The sooner you protect oral hygiene, the better the effect, so be sure to let your child get into the habit of brushing his teeth in the morning and evening, and don't eat too many sweets to avoid tooth decay. When a black hole is formed in a tooth, it will be difficult to control, so the sooner you protect your teeth, the better.
