Many kindergarten dolls because usually love to eat sweets, but also do not pay attention to oral hygiene, will appear different degrees of caries in the molar teeth. Look at the child’s cheeks swollen high, can’t eat or sleep, the whole family began to be entangled – the baby’s “bad teeth” is to pull or treatment, no one can not decide! Or listen to the stomatologist’s professional guidance. “Milk teeth” is the first set of teeth in life, the general baby in half a year old when the first eruption, six years old before the flush. After that, the child enters the “replacement period” – the milk teeth fall out one after another, the permanent teeth erupt. Until the age of 12 or 13, permanent teeth become our second set of teeth. Just because the milk teeth sooner or later is to be replaced by permanent teeth, when the child’s milk teeth caries, many parents think, anyway, milk teeth are to be replaced, since the child’s pain is unbearable, it would be better to pull out, but in fact, we must analyze the specific problem. Milk teeth should not be easily removed decayed milk teeth should not be easily removed. If the premature extraction of milk teeth will affect the normal chewing function of children, while the loss of permanent teeth eruption of the induction function, is not conducive to the maintenance of the gap, may cause occlusal disorders and dental irregularities. For caries of milk teeth, the general principle is to try to repair first. If the cavity is shallow, fill it directly after treatment. For deeper cavities, root canal treatment is required. Many parents are concerned and resistant to root canal treatment because they think it is long and painful and are afraid of the impact on the permanent tooth germs at the base. Although the principles of root canal treatment for children’s baby teeth are the same as those for adults, the methods and materials used are very different, and the treatment time is shorter, acceptable to most children, and anesthesia is usually not required. The entire root canal operation is done in the baby tooth, so there is no need to worry about the permanent embryo being affected. If the cavity is large and the tooth is thin, do not chew on hard objects after filling and restoration, so as not to break the tooth. In addition, after the restoration of milk teeth, it is also necessary to have a review every six months. Due to the small caries cavity in the front teeth, the filling is easy to fall off, and should be filled again in time after falling off. Bad teeth with no restorative value should be extracted Caries should be extracted or not, which requires the physician to make a judgment. Decayed deciduous teeth that are close to replacement stage can be extracted. Badly decayed baby teeth with no restorative value should be extracted promptly. Cavities encroach on the dental nerve causing severe pain, seriously interfering with the normal life of the child, in this case milk teeth should also be extracted. Because the pain will lead to the child often use the non-painful side of the teeth to chew food, which will have an impact on the development of the jaw and face; in addition, sometimes the diseased tooth is not removed, the pulp of the inflammation can not be inhibited, will be downward invasion of the alveolar bone, which affects the normal development of the permanent tooth embryo. At this time the tooth must also be extracted. Many parents wait for their children to experience severe pain and large holes in their teeth before coming to see a doctor, which is of course much more troublesome to deal with. In fact, early tooth decay may be just a small white spot. As for tooth decay in the fossa area, it may be just a small black spot at the earliest. With the development of caries, the small black spot will gradually become bigger, after which the caries will continue to develop and the surface will collapse to form a small hole. If left untreated, the small hole will become a large one, and you will begin to experience soreness when eating hot or cold foods or sweets. It is only when caries continues to deteriorate and bacteria invade the pulp causing pulpitis that the tooth begins to ache severely. Therefore, parents should be alert to the initial form of dental caries and seek early treatment. At the same time, let the child develop a good habit of brushing teeth carefully in the morning and evening, especially after drinking drinks, after eating with water rinse mouth to dispose off the surface of the teeth residual food. Doll tooth extraction mom attention baby after tooth extraction, the wound is usually in about 10 days of basic healing, parents in this period to properly protect the wound. Otherwise there is a risk of excessive bleeding after tooth extraction, and even cause wound infection, inflammation, swelling, limited opening of the mouth, pain, and prolonged wound healing time, and in severe cases can cause complications of dry socket. After tooth extraction, you should bite the gauze cotton ball on the extraction wound and spit it out after half an hour. Biting the gauze cotton ball, on the one hand, can stop bleeding, but also can make the trauma of the blood clot coagulation, conducive to wound healing. The bleeding usually stops in about half an hour. Spit out the cotton ball too soon is easy to cause bleeding, but the gauze cotton ball should not bite too tight for too long, or in turn increase the chance of infection. It is normal to spit out the cotton ball with a small amount of blood. Don’t lick or suck the wound with your tongue, and don’t touch the wound with your fingers or toothpicks. Don’t spit all the time, because repeated spitting is easy to cause bleeding, and you can swallow when there is more saliva in your mouth. Eating after tooth extraction needs to wait until after 2 hours, because anesthesia can maintain 1-2 hours, eating too early will bite the lips and mucous membranes by mistake. In order to prevent flushing out the clots in the wound, which may cause further bleeding, you may not brush your teeth or rinse your mouth on the day of tooth extraction. If there is still more bleeding after tooth extraction, and even if you can spit out clots, you should go to the hospital for examination to see if the extraction site continues to ooze blood, and to stop the bleeding in time. 24-48 hours after tooth extraction, if the mouth is mildly restricted can be appropriate to do hot compresses or physical therapy.
