What Is Mouth Sores and Oral Discomfort?

Mouth sores, including canker sores, can be painful and make eating and speaking uncomfortable. Dry mouth, irritation from dental appliances, infections and some medications can also cause oral discomfort.

Sores that last longer than two weeks, or white or red patches that do not go away, always need a dentist’s or physician’s assessment.

Where Compounding May Fit

Commercial products come in set strengths and formats. Sometimes a prescriber wants something different: another strength, a rinse, gel or lozenge format, or a flavour that is easier to tolerate. In those cases the prescriber can write a prescription for a compounded preparation, and our pharmacists prepare it to those specifications.

Compounding is not a first step and not a substitute for an assessment. Whether a compounded preparation is appropriate is your prescriber’s decision, made after considering your history and the commercial products already available.

Please note: We do not promote specific compounded preparations or ingredients to the public. Your prescriber decides what, if anything, to prescribe.

Questions to Bring to Your Appointment

  • How long have the sores or discomfort been present?
  • Do they recur, and do they follow stress, certain foods or new products?
  • Do you wear dentures or braces?
  • Are you having difficulty eating, drinking or swallowing?
  • Which medications and supplements are you taking now?

When to See a Prescriber Promptly

See a dentist, physician or nurse practitioner if a sore lasts more than two weeks, if you find a lump or a white or red patch, or if you have difficulty swallowing. Seek urgent care for swelling of the mouth or throat, or difficulty breathing. This page is educational and does not replace a medical assessment.

Mouth Sores and Oral Discomfort FAQ

Can a pharmacy compound a preparation for mouth sores and oral discomfort without a prescription?

No. A compounded preparation is made against a prescription from an authorized prescriber such as a physician or nurse practitioner.

What is a canker sore?

A canker sore is a small, painful sore inside the mouth. It is not contagious and usually settles on its own, but frequent or large sores should be assessed.

Can medications cause dry mouth?

Yes, many do. Tell your pharmacist and prescriber about dry mouth so your medications can be reviewed.

Does insurance cover compounded preparations?

Coverage varies by plan. Call us with your prescription and we will check what your plan allows before preparing it.

How long does preparation take?

Many preparations are ready within 24–48 hours of receiving a complete prescription, though timing depends on the preparation and ingredient availability. We will confirm when you call.

Do you offer delivery?

Yes, we deliver across the GTA. Call (647) 348-2323 for details and timing.

When should I contact my prescriber or pharmacist?

Contact them if you notice a reaction, new symptoms or questions after starting a prescribed preparation. For difficulty breathing or swelling of the face, call 911.
