Canker sores are not contagious and are not caused by sexual activity or oral contact with another person. They are typically triggered by factors such as stress, certain foods, or underlying health issues. While some foods may irritate the mouth and potentially lead to canker sores in susceptible individuals, oral contact itself does not directly cause them.
