Renfrew Pharmasave

Canker sores (aphthous ulcers) are small, painful spots inside the mouth that usually heal within 1–2 weeks. They’re common, not contagious, and may be triggered by stress, mouth injury, certain foods, or vitamin deficiencies. Our pharmacists can suggest treatments to ease pain, promote healing, and reduce recurrences.
