Dental treatment is possible during pregnancy, and it is generally recommended that oral problems be resolved during the preparation stage, i.e. before pregnancy. Wisdom teeth that should be extracted should be extracted, cavities that should be filled should be filled, and a thorough periodontal systemic treatment to get rid of periodontitis or gingivitis must be done before pregnancy. If for some reason a cavity or toothache is found during pregnancy it is essential to get treatment. Pain caused by pulpitis or periodontal inflammation may also lead to miscarriage or premature birth. If combined with interstitial infection, it may even be life-threatening. Generally 4-6 months of pregnancy, these 3 months are relatively safe. If treatment is not particularly urgent, it can be placed in these 3 months. If there is severe pain and significant swelling, you should seek medical attention quickly. At this time, you must not delay the condition because you are worried about the baby or other factors, and you can ask the obstetrics and gynecology department to consult together with the dentistry department for treatment.
