一、月经期、妊娠期与拔牙:月经期的妇女,拔牙后牙槽可能有代偿性出血。因此,月经期间最好不要拔牙。有的医生认为妊娠期是拔牙的禁忌症。我们的体会是除困难牙和阻生齿外,都可在此期间拔除,但必须指出,对于有习惯性流产或有流产史者,应在保胎的情况下进行。对于妊娠初3个月和妊娠最后2个月的孕妇拔牙时要慎重。 First, the menstrual period, pregnancy and tooth extraction: women during menstruation, extraction tooth alveolar may have compensatory bleeding. Therefore, it is best not to pull teeth during menstruation. Some doctors think that pregnancy is the contraindication of tooth extraction. Our experience is that in addition to difficult teeth and impacted teeth, can be removed during this period, but it must be pointed out that for those who have a habitual abortion or abortion history should be carried out in the miscarriage. For the first 3 months of pregnancy and the last 2 months of pregnancy, pregnant women to be careful when extracting teeth.
