If the plaque isn't removed, it can cause gingivitis. Red, swollen, and tender gums are more likely to bleed. If you already have gingivitis, the condition is likely to worsen during pregnancy. If untreated, gingivitis can lead to periodontal disease, a more serious form of gum disease.
Pregnant women are also at risk for developing pregnancy tumors.
These are growths that develop when swollen gums become irritated. Normally, the tumors are left alone and will usually shrink on their own. But if a tumor is very uncomfortable and interferes with chewing, brushing or other oral hygiene procedures, the dentist may decide to remove it. You can prevent gingivitis by keeping your teeth clean, especially near the gumline. You should brush with fluoride toothpaste at least twice a day and after each meal when possible.
