Pregnancy can make gums react more strongly to plaque. You may see bleeding, swelling, sensitivity, diet changes, nausea, and more snacking. That does not mean you should wait until after birth.
What matters for prevention
- gentle brushing twice a day with fluoride toothpaste;
- daily interdental cleaning;
- water after vomiting or acid, without immediate hard brushing;
- tell your dentist how far along you are and any obstetric notes;
- do not take medicines or pain relievers without checking with your clinician.
When to get care
Pain, swelling, pus, a high fever, trauma, heavy bleeding, or not being able to eat normally need a dentist. Preventive and needed dental care in pregnancy is planned with your clinicians; delaying an infection can be worse.
