Your gums and teeth are also affected during pregnancy. Between the second and eighth month, gums may swell, bleed, and become red or tender. Large lumps may appear as a reaction to local irritants. However, these growths are generally painless and are not cancerous. They may require professional removal, but usually disappear sometime after delivery. Periodontal health practices should be part of your prenatal care. Any infections during pregnancy, including periodontal infections, can place a baby’s health at risk.
