Canker sores (recurrent aphthous ulcers) are common, painful sores inside the mouth — on the cheeks, lips, tongue, or floor of the mouth. Most classic, recurring canker sores can be treated with a topical prescription. A sore that will not heal after 2 weeks, or one that comes with other warning symptoms, needs an in-person look instead.
If treatment is appropriate, your physician can send a non-controlled prescription to your pharmacy and provide portal instructions for the next step.
