What parents should be careful about is that the child should be referred to an orthodontist after trauma and fracture of the primary teeth. An orthodontist can prevent deformities in the child’s face through simple orthodontic appliances, prevent his face from tilting in the future, and undergo complex surgery and treatments. Sometimes for reasons not yet fully understood, the mandible grows more on one side than the other. The result is a deviation of the lower jaw. Sometimes, some permanent teeth are missing in the patient’s jaw, which causes problems in the dental system. Sometimes the presence of extra teeth causes more teeth than normal, which leads to skewed teeth. The most common extra tooth is the front tooth in the middle of the upper jaw. Sometimes one or more teeth are large or small, which makes the dental system irregular. Premature loss of primary teeth is another cause of malformations. The idea that primary teeth are temporary and therefore worthless is completely wrong. One of the most important tasks of primary teeth is to maintain space in the jaws so that the time for the permanent teeth to come in can be reached. If the primary teeth fall out prematurely, the adjacent teeth will move into the existing empty space, and eventually the permanent tooth may not erupt (remain hidden) or grow out of order. The most important way to prevent these problems is to protect the child’s dental health so that they do not decay. If the primary tooth is lost prematurely, the patient should be given a Space Maintainer to maintain the empty tooth space. Some babies breathe through the mouth instead of the nose. Oral breathing may be due to partial or complete obstruction of the respiratory tract from the nose or causes such as sinusitis, allergies or enlarged tonsils, nasal polyps or others. In this case, in addition to orthodontics, the patient must be examined by an otolaryngologist to treat the patient’s oral breathing problem. In all cases, timely treatment can prevent some acute problems and jaw surgery.
