What Causes Canker Sores?
9. Risk Factors
Canker sores can happen in anybody, including the young, fit, and healthy. They tend to be more common in young adults and adolescents, although they can affect people of all ages. They can affect both sexes, but they are more likely to be found in females than in males.
Another potential factor is stress, while people that have recently been ill or run down are also at a higher risk. The sores are also more likely to be found in people if there is a history of them in the family. They are also more likely to be found in people who are likely to be exposed to certain triggers such as allergens.
