If the child’s milk teeth are loose due to trauma, it is important to check the location and age of the child’s milk teeth, if it is common to have trauma to the front teeth, especially the upper front teeth. If the child is around 5 or 6 years old, as the child is approaching the stage of alternation of the front teeth, the loose milk teeth can be considered to be extracted directly, preserving the corresponding gap and waiting for the permanent teeth to erupt. If the child’s milk teeth will take a longer time to be replaced, you can consider the method of fixing the loose teeth together with the surrounding teeth, thus acting as a splint fixation, and observe the effect of fixation for about 3 to 4 weeks.
