Pregnancy toothache can be treated in the middle of pregnancy if it is caused by pulpitis. A toothache during pregnancy needs to be treated carefully. A thorough dental examination should be performed before preparing for pregnancy and problems should be treated promptly. If tooth decay is not treated in time and develops into pulpitis or apical infection during pregnancy, painful eating or nighttime pain can be very intense and it is often difficult to sleep or wake up from sleep in pain. If the toothache develops during pregnancy, the tooth can be treated in the middle of pregnancy, that is, from the fourth to the sixth month of pregnancy. If the tooth nerve is inflamed and the tooth becomes pulpitis, the root canal should be disinfected after killing the nerve and then the root canal should be filled. If the dental treatment is performed in the first trimester of pregnancy, emotional stress may cause miscarriage. If the dental treatment is performed in the second trimester, it may cause premature delivery, both of which are dangerous. Dental treatment can be performed when you are more stable in the middle of the fourth to sixth month of pregnancy. It is possible to have dental treatment for a toothache between the fourth and sixth months of pregnancy, and it needs to be done carefully.
