To answer directly, it is good to have root canal treatment for children’s milk teeth, but the question itself does not make much sense, because root canal treatment itself is an operation, a treatment plan for certain diseases. This question is the same as asking whether it is good for children to take medicine when they are sick. It’s the same question: medication can definitely cure the disease, but there may be a little bit of side effects, but weighing the relationship between the cure and the medication, the child still needs to take the medication. The same is true for root canal treatment. If a child’s baby tooth has a more serious problem, such as pulpitis or periapical inflammation of the baby tooth, the only way to treat the tooth is through root canal treatment. The only way to get rid of the inflammation is through a root canal treatment program, which, if not done, will only worsen the condition. The periapical infection of the milk tooth may affect the eruption of the permanent tooth below, causing damage to the crown of the permanent tooth, which we call Turner’s tooth. Sometimes the decay of the baby tooth causes early loss of the baby tooth, and also creates an uneven alignment of the whole tooth, which affects the nutritional absorption and facial shape of the patient. Therefore, root canal treatment of baby teeth is a necessary operation for pulpitis and periapical infection of baby teeth, and sometimes it is a necessary operation, not simply a question of whether it is good or not.
