Some causes of swollen gums are gingivitis, malnutrition, pregnancy, infection, and sensitivity to toothpaste or mouthwash, states MedlinePlus. Swollen gums are bulging or enlarged gums that may also develop due to poorly fitting dentures or side effects of medicine, such as calcium channel blockers, Dilantin and phenobarbital.
Bleeding accompanying swollen gums may be a sign of gum disease, says BootsWebMD. Oral health issues may lead to tooth decay and tooth loss. Home care for swollen gums includes eating a healthy diet, avoiding alcohol and tobacco, and brushing teeth regularly, notes MedlinePlus. Swollen gums that last more than two weeks require professional evaluation.
