Whether children's dental caries need treatment may require taking X-rays of the teeth, or it can be judged based on the child's age. If a child around seven or eight years old has decay in the front teeth, these teeth can soon be replaced, and treatment may not be necessary. However, if the molars at the back, which are replaced at around twelve or thirteen years of age, are decayed, then it is necessary to treat these early by removing the decay and filling the teeth. Otherwise, bacteria may further infect the dental nerves, causing pain. If children's dental caries are not timely treated, it can also affect chewing. During childhood, the jawbone undergoes significant development. If the chewing function is impaired, it can affect the development of the jawbone, hence early treatment of children's dental caries is essential.
