Baby cavities a big hole, parents think, “anyway, after all to replace the teeth, first ignore it”, “a few bad teeth, does not affect the food is good”; baby fell, knocked teeth are a little shaky, parents look, knocked a little broken, but think that the impact is not big, so also do not think. But I think the impact is not big, so I do not think …… but in fact, these “rotten teeth” if not dealt with in a timely manner, is also lurking a lot of harm. The actual fact is that if you don’t take care of these “rotten teeth” in a timely manner, there is a lot of harm lurking. We know that the oral mucosa is a very thin layer of tissue, with sharp edges are always rubbing in the same place, even if it has a strong regenerative capacity, can not eat, over time, can form oral ulcers. And the oral mucosa plays an important role in protecting various tissues under the mucosa and immune barrier, once “broken” it, like the door is wide open, for a variety of germs to “invade” to provide a convenient. When the resistance is low, these “latent” germs will come out to “make waves” and induce various diseases in the whole body: fever, toothache, headache, pneumonia, bronchitis, etc. The teeth are the first gate of the digestive system, when there are “rotten teeth”, it will affect the normal chewing function to a certain extent, so that the food eaten does not get a good chewing process such as cutting, tearing, grinding, etc., directly into the gastrointestinal tract, which will not only increase the burden on the gastrointestinal tract, and This will not only increase the burden on the gastrointestinal tract, but also affect the digestion and absorption of food, in addition, because of bad teeth, children will not like to eat meat or vegetables and other food that is not easy to bite and easy to plug teeth, over time, it will develop a bad habit of partial eating, affecting the balanced intake of nutrition for children. Influence the normal development of permanent teeth If the decayed baby teeth are not treated, because there is a hole, the food is easily stuffed inside when eating, which can make the bacteria gather for a long time and lead to the decay of other teeth. When the cavity continues to go deeper and invade the nerve, it can lead to severe toothache and seriously affect the normal study and life. If the inflammation continues to develop to the root tip, it may affect the normal development of the permanent tooth embryo, and even the enamel development disorder and malformation of the permanent tooth. The development of the jaw is affected by the rotten teeth, the child may chew more on the opposite side of the teeth because it is uncomfortable to chew with the rotten teeth, over time, it has developed the habit of chewing on the side, and for a long time, the facial development can become more and more asymmetrical, in short, when a child is found to have rotten teeth, do not take it seriously, do not wait until the teeth have rotten to affect the normal life of the child In short, when you find a child with rotten teeth, don’t take it lightly, don’t wait until the tooth is so rotten that it affects the child’s normal life, then bring it to deal with. Of course, the most important thing is to do a good job of prevention, keep the oral cavity clean and regular oral examination is very necessary, parents should educate their children to develop a good habit of brushing their teeth before going to bed, rinse their mouth after eating, at the same time, it is best to take the child to the dentist every three months to six months to do an oral health care, timely detection of problems, as early as possible to give the necessary intervention.
