You can pull out your teeth when you are pregnant, especially impacted wisdom teeth. Wisdom teeth that may have inflammation or residual roots and crowns in the mouth should be pulled out before pregnancy, or repaired after root canal treatment. If inflammation occurs during pregnancy, or redness, swelling, heat and pain occur, it is generally difficult to treat. Therefore, tooth extraction can be carried out before pregnancy. If there are symptoms of oral anti-inflammatory drugs after tooth extraction, you can wait for a period of time to prepare for pregnancy, which can ensure that there is no dental disease and no oral problems during pregnancy, avoid swelling and pain during pregnancy, and avoid affecting the fetus. Moreover, it is best to thoroughly treat periodontal disease before pregnancy, and you can wash your teeth and apply medicine locally. Maintain periodontal health, repair dental caries, remove residual roots and crowns, and remove impacted wisdom teeth, and there will be no problems in the oral cavity.
