(HealthDay News) -- Gums can swell and become tender as a result of gingivitis, a side effect of certain drugs or pregnancy.

The U.S. National Library of Medicine suggests how to care for swollen gums:

• Don't expose your gums to irritating substances such as tobacco, mouthwashes or alcohol.
• Eat a balanced, nutritious diet.
• Try a different brand of toothpaste if your gums appear sensitive to your toothpaste.
• Practice good oral hygiene, including a periodontal or dental visit every six months.
• If your condition is caused by a drug, ask your doctor about changing medications. Don't switch any medication before you consult with your doctor.
