Causes of Sore, Swollen, and Bleeding Gums: Canker Sores

Common culprits behind painful gums are canker sores, or mouth ulcers. These painful sores can develop anywhere inside the mouth, including on the gums, and they often have a whitish center with red around the edges. You may experience one canker sore at a time, making only one area on your gums sore, or you may have multiple sores at the same time throughout your mouth.

While researchers don't know exactly what causes canker sores, and they're not contagious, there may be bacterial or viral involvement. People with certain autoimmune diseases may also be more likely to suffer gum problems caused by canker sores. Canker sores often recur over time.
