One of the things I'm worried about while raising a small child is brushing their teeth. Many people are worried, such as "When should I start brushing my kids teeth?" "I don't want them to have cavities, but my child doesn't like brushing their teeth."  To prevent cavities in your child's teeth, you need to be careful about their diet during the period of tooth renewal, but it is important to brush their teeth the right way. So, this time, I will introduce when to start brushing your child's teeth, how to brush properly, and precautions to prevent your child's teeth from becoming cavities.When should I start brushing my child's teeth?Basically, children's toothpaste should be used "when milk teeth begin to grow". Teeth grow around 2 to 2 years and 6 months. When your kids are about three years old, let them start practicing brushing teeth by themselves. They can't polish it well at first, but don't let them do too much and motivate them. As the mother happily polishes next to them, the child also imitates. Once they get used to it, it's a good idea to teach them how to brush it correctly little by little. It is very important to foster independence, but on the other hand, there are still many leftovers until the lower grades of elementary school, so parents should do the final finishing cleaning.How to brush your child's teeth correctlySo how do you specifically brush your child's teeth every day? Introducing the correct toothbrushing method, such as how to choose and move a toothbrush.How to choose a toothbrushThe important point when choosing a toothbrush is size. If you use something that does not fit, you will not be able to polish even the smallest details, leaving unpolished parts. When choosing a toothbrush, use the target age as a guide and choose a toothbrush that fits your child's mouth. It is also important to use a toothbrush with your kid's favorite color and character so that they will like to brush their teeth.How to move the toothbrushThe next most important thing after choosing a toothbrush is how to move the toothbrush. As points to note, "how to apply the tip of the hair", "how to move", and "adjustment of force" are the points. Brush the back, front, and meshing surfaces of the teeth at least 20 times each.How to brush the teeth of a small childHelp brush your child's teeth when they start to grow. The basic posture for brushing a child's teeth is laying down. Brush the kid's mouth with the back of your head resting on your knees. Gently grasp the toothbrush with a pen and gently flip the child's lips with your other hand. At this time, it is important to keep the head firmly fixed so that the child does not move his head suddenly.Brush the teeth so that only the tip of the toothbrush hits your kid's teeth. If the brush hits the gums, it will hurt your child, so be careful not to hit the gums with the brush. However, avoiding the gums too much tends to leave dirt between the teeth and gums. Use gentle force to brush the area between the gums and teeth.How to prevent tooth decay in childrenFinally, I will introduce how to prevent tooth decay. There are some things you can do, so please refer to them.Make a habit that is less likely to cause tooth decayDecide when to eat a snack. I want to make it about 10 to 20 minutes so that they don't eat sloppy. It is also effective to "gargle" after eating. For children who find it difficult to brush their teeth after each meal, as it makes it difficult for food to remain in the mouth, let them just gargle.Choose foods that are less prone to tooth decayGood snacks, such as rice crackers and crackers, do not contain sugar and do not stick to your teeth. The one that does not easily remain in the mouth is also good. Although it contains sugar, ice cream that melts quickly is less likely to remain in the mouth than caramel.Brush your teeth carefully at nightThe best is to brush your child's teeth thoroughly after each meal. However, I think it's difficult to brush their teeth well every time, so it's a good idea to be soft even at night. When you are sleeping, the amount of saliva produced is reduced, which makes you more likely to have tooth decay. Therefore, brush your child's teeth at night so that no stains remain.
