Canker Sores: What You Need to Know
Canker sores (also called aphthous ulcers) are small, painful ulcers that form inside the mouth — often on the inner lips, cheeks, or tongue. Unlike cold sores, canker sores are not contagious and usually heal on their own within 7–10 days, but severe or frequent sores can interfere with eating, speaking, and daily life.
If you’re struggling with painful or recurring mouth ulcers, a Centrum Pharmacist in the Ottawa and Orleans area can provide fast relief and help you avoid further discomfort. Read on to learn how a Centrum Pharmacist can help.
How a Centrum Pharmacist Can Help
Under Ontario’s Minor Ailments Prescribing Program, pharmacists are authorized to assess and prescribe treatment for canker sores when appropriate.
At Centrum Pharmacy, our pharmacists can:
- Assess the severity and cause of your mouth ulcer(s).
- Recommend or prescribe medicated mouth rinses, topical treatments, or oral medications.
- Provide guidance on avoiding triggers (e.g., stress, certain foods, trauma).
- Advise when a physician referral may be needed — especially for large, frequent, or non-healing sores.
