Your risk of aphthous stomatitis, or canker sores, an ulcer inside of your mouth, is increased by your gender and family history. Women are more prone to getting canker sores than men. Also, if members of your family tend to get canker sores, then you are at a higher risk of developing them as well.
American Dental Association answeredFatigue, stress or allergies can increase the likelihood of a canker sore (small ulcers inside the mouth with a white or gray base and a red border). Some women may be more prone to them in their premenstrual cycle. A cut caused by biting the cheek or tongue, or reactions from hot foods or beverages may contribute to canker sore development. Intestinal problems, such as ulcerative colitis and Crohn's disease, also seem to make some people more susceptible.

There are a couple of conditions that raise your risk factor for developing aphthous stomatitis. If other people in your family have had canker sores, your chance of getting them is higher. Also, women are more likely than men to get this type of mouth ulcer.
