During pregnancy, due to the increased level of estrogen in the body, the gums are very easy to bleed, and if the oral hygiene is not good, the gums will be enlarged and swollen, bleeding violently, seriously affecting the normal life.

Dental textbooks clearly point out that teeth extraction is not advisable in the first and second trimesters of pregnancy, as it can easily cause miscarriage and preterm labor.

Even after the birth of wisdom teeth extraction is also a certain risk, because at this time the mother is in the breastfeeding period, once the extraction of the teeth after the infection, you need to use medication and can not breastfeed the child, then a long time is easy to return to the milk.
