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.
