Canker sores refer to small and shallow lesions that appear either in your mouth’s soft tissues or in the area underneath your gums. These sores actually go by many names, such as aphthous ulcers1 or recurrent aphthous stomatitis (RAS).2 However, despite their small size, canker sores can be very painful and could lead to eating and/or talking difficulties.
When Are People Most Prone to Have Canker Sores?
Unfortunately, no one knows exactly when canker sores will affect you. These lesions do not pick an age, so anyone can develop canker sores — even children as young as 2 years old may have them.3 However, they tend to occur most often among teens and young adults. In fact, peak incidence of canker sores is recorded during these stages.4
Canker sores are more common in women compared to men,5 and may occur more among Caucasians, nonsmokers and people with high socioeconomic status.6
