Wisdom teeth do not have to be removed before pregnancy, but can be categorized into those that need to be removed and those that do not. 1. Conditions that require removal: This is mainly due to the fact that the wisdom teeth are not fully developed and have covered the gingival flap to form a deeper blind pocket, causing food debris to become embedded in the blind pocket and causing swelling and pain. In this case, extraction may be recommended to avoid bacterial infection during pregnancy, resulting in maxillofacial swelling and affecting the development of the fetus. If the wisdom teeth are blocked in the middle and form a triangular gap with the neighboring teeth, it will be easy to plug the teeth, and also need to be removed. 2. Do not need to be removed: If the growth of wisdom teeth is good and the position is positive and has the normal chewing ability, then such wisdom teeth are not easy to cause wisdom teeth pericoronitis, there is no need to be removed. Before pregnancy, you should go to the stomatology department for oral examination, treatment of caries, removal of inflammable wisdom teeth, in order to safely get through the pregnancy to make good oral preparation.
