Pregnancy can make gums react more strongly to plaque. Bleeding, swelling, sensitivity, dietary changes, nausea, and more frequent snacking can all show up. That doesn't mean you should put up with it until after delivery.
What matters for prevention
- gentle brushing twice a day with fluoride toothpaste;
- daily interdental cleaning;
- water after vomiting or something acidic, instead of brushing hard right away;
- telling your dentist how far along you are and any details from your obstetrician's care;
- not taking medications or pain relievers without checking with your doctor.
When to see someone
If there's pain, swelling, pus, a high fever, an injury, heavy bleeding, or you can't eat normally, you need a dentist. Preventive and necessary dental treatment during pregnancy is discussed with your doctor, and delaying an infection can be worse.
