Children begin to alternate between milk and permanent teeth from the age of 6. Should loose milk teeth be left to fall out naturally or should they be extracted in the hospital? Usually, it is necessary to observe and consider active extraction if the loose teeth are going to cause chewing disorders and irritate the surrounding mucosal tissues. This is especially true if the baby teeth refuse to “give way” on time and the permanent teeth come in and have to emerge from the side, giving the child a “double row of teeth”. If you have a “double row of teeth”, you should go to the hospital early to find a doctor to pull out the late deciduous teeth, so that the permanent teeth stand to the correct post, otherwise the teeth will not look good in the future.
