Answer

Recurrent aphthous ulcers (canker sores) begin in childhood or adolescence, with peak onset in persons aged 10-19 years. Frequency and severity diminish with age. Major aphthous ulcers (canker sores) may begin soon after puberty. Herpetiform recurrent aphthous ulcers (canker sores) tend to affect older persons.
