Throughout life, hormonal changes can affect tissues throughout the body—including the gums. Shifts in hormone levels during puberty, menstruation, pregnancy, oral contraceptive use, and menopause can make the gums more sensitive to plaque, increasing the risk of inflammation or gum disease. Being aware of these changes helps you take proactive steps to keep your smile healthy at every stage.

Puberty

During puberty, rising hormone levels increase blood flow to the gums, making them more reactive to plaque and food particles. This can cause swelling, redness, and tenderness.

Menstrual Cycle

Some women notice gum changes in the days leading up to their period—such as bleeding gums, swelling, or small sores inside the mouth. These symptoms usually clear once menstruation begins.

Pregnancy

Hormonal shifts during pregnancy—especially between the second and eighth months—can lead to red, swollen, or bleeding gums (often called pregnancy gingivitis). Some women may also develop temporary gum growths called pregnancy tumors, which are non-cancerous and often resolve after delivery.
Untreated gum infections have been linked to pregnancy complications, so periodontal care should be part of your prenatal health plan.

Oral Contraceptives

Synthetic hormones found in birth control pills can sometimes cause gum swelling, bleeding, or tenderness. Let your dentist know about all medications you’re taking, as some antibiotics can reduce the effectiveness of oral contraceptives.

Menopause and Post-Menopause

Hormonal changes during and after menopause can cause dry mouth, burning sensations, or altered taste (such as salty or metallic flavors). Reduced saliva flow can also increase the risk of decay and gum disease.
