If a young child does not cooperate with the filling, there are many ways to do it. Coercion can be used by wrapping the child in a special blanket and prying the tooth open to give the child treatment, but the disadvantage of this method is that it is more risky, and the child is prone to accidental inhalation in the midst of shouting and screaming, which can create a psychological shadow on the child, so this method has been gradually phased out nowadays. There is also laughing gas inhalation, which allows the child to inhale a certain amount of laughing gas, and be able to cooperate with the filling after their emotions are handled smoothly. There is also general anesthesia, which needs to be carried out in the operating room, general anesthesia fillings make the child feel as if he/she has slept all the teeth have been filled, this method is both safe and efficient for uncooperative young children, and is now being carried out in many hospitals.
