Pregnant women should not take painkillers for toothache because painkillers can have adverse effects on fetal development and can cause fetal malformation in serious cases. Especially in early pregnancy, which is a critical period for the development of the fetus, if you take drugs indiscriminately in early pregnancy, it will affect the development of the baby. There are many reasons for toothache during pregnancy, which may be due to fire or gingivitis. There are also wisdom teeth, which can also cause toothache. It is best to go to a regular hospital for examination, identify the cause and then treat it reasonably under the guidance of the doctor. Pay attention to oral hygiene, if it is caused by gingivitis, it is best to brush your teeth with herbal toothpaste. It is also recommended to rinse your mouth with light salt water, which can improve the symptoms of toothache. If it is caused by fire, it is better to drink more water and eat more vegetables and fruits. If it is caused by wisdom teeth, it is best to wait for the wisdom teeth to be removed in the hospital after delivery to avoid causing pericoronitis of wisdom teeth.
