Dental issues can pop up during pregnancy and I remember how uncomfortable a sore tooth can be. Many dentists recommend doing any necessary dental work in the middle of pregnancy, and by 28 weeks most procedures are still possible with the right precautions. The key is to let your dentist and obstetrician know you're expecting so they can choose safe anaesthetics and x‑ray shields. In the meantime, gentle saltwater rinses and good oral hygiene can help ease discomfort. Don't ignore a bad toothache, though—an untreated infection can be harder on you and baby than getting it fixed.
