More Than a Mouth Sore: Oral Ulcers and Lupus
What the Lupus Canada community survey tells us about oral ulcers
By Dr. Amrit Bhogal
For people living with lupus, oral ulcers can be painful, recurrent and disruptive to everyday life. Dr. Amrit Bhogal explores what Lupus Canada’s community survey tells us about oral ulcers and lupus, and why listening to patients’ experiences matters.
Mouth ulcers are easy to underestimate when you are not the person experiencing them. Hidden inside the mouth, their effects often go unnoticed unless someone takes the time to ask. But when ulcers become painful or recurrent, they can affect far more than the mouth. Eating, speaking, brushing, and enjoying a meal can all become difficult.
Over time, people adapt. They avoid certain foods, speak less when talking hurts, or change how they care for their teeth. To others, these changes may seem small or go entirely unnoticed. To the person living with them, they can gradually affect comfort, confidence, and quality of life.
What the survey revealed
Because much of this burden is hidden, Lupus Canada sought to better understand how oral ulcers affect people living with lupus. In a community survey, 35 respondents shared how often their ulcers occurred, how painful they became, how they affected daily life, and what kinds of support or treatment they had received.
Although a survey of this size cannot represent everyone living with lupus, the responses provide an important window into an experience that is often overlooked. Among respondents, 51% experienced oral ulcers monthly or more often, while 40% rated their worst pain as 7 out of 10 or higher.
The effects extended beyond pain. Eighty percent avoided certain foods, 77% had difficulty eating, and 74% found it harder to brush or maintain their oral hygiene. For 34% of respondents, oral ulcers also caused emotional distress.
Yet the support respondents received did not always reflect that burden. Saltwater rinses were the most commonly used remedy, and 66% had never been prescribed anything for their mouth sores. Some respondents also described feeling dismissed when they raised the issue with healthcare providers.
Relief matters
Interestingly, almost nobody asked for a cure. Instead, respondents focused on practical improvements: faster healing, better pain relief, and help before the pain reached a point where nothing seemed to work.
This distinction matters. People living with recurrent oral ulcers may understand that the underlying cause cannot always be removed. What they are asking for is a way to make each episode shorter, less painful, and less disruptive to everyday life. Some wanted something even more fundamental: to have their experience believed and taken seriously.
Why acknowledgment matters
As healthcare professionals, we often rely on pattern recognition. It helps us recognize common conditions and make decisions efficiently. However, it can also become a shortcut. When an ulcer looks familiar, we may recognize what it is without fully understanding what it is doing to the person experiencing it.
A brief examination cannot reveal how often the ulcers return, whether they make eating or brushing painful, or whether someone has quietly changed daily habits to cope. We only discover that by asking with curiosity.
Empathetic care begins with listening and reflecting back what the patient has described. It also means examining the mouth, explaining the nature of oral ulcers, considering possible contributing factors, discussing realistic options for relief, and following up when appropriate. Even when a provider cannot offer a cure, acknowledgment may give someone the confidence to continue seeking the care and relief they need.
Managing an active ulcer
During an episode, try to keep the mouth clean as comfortably as possible. A soft toothbrush and gentle brushing may be easier to tolerate. Soft or cool foods may feel better, while spicy, acidic, rough, or personally irritating foods may increase discomfort. A pharmacist, dentist, or physician can help identify suitable pain-relieving, protective, or prescription options based on the type and severity of the ulcer.
One option for aphthous ulcers is OralMedic, a single-use topical treatment applied directly to the ulcer. It is intended for common mouth ulcers inside the mouth, not cold sores, and should be used only as directed. Because not every mouth lesion is an aphthous ulcer, speak with a healthcare professional if you are unsure what you have or whether the product is suitable for you.
When to seek care
Speak with a dentist or physician if an ulcer lasts longer than three weeks, looks or feels different from your usual ulcers, is becoming more painful or red, or keeps returning. Recurrent ulcers deserve assessment, particularly when they interfere with eating, drinking, speaking, or oral hygiene.
You are not alone
The survey cannot represent every person living with lupus, but it makes one thing clear: recurrent oral ulcers are not trivial to the people experiencing them. Their pain and daily impact deserve to be heard. If oral ulcers are affecting your life, describe that impact clearly and ask about your options. You deserve care that looks beyond the sore and listens to the person living with it.

Dr. Amrit Bhogal is a practicing dentist and founder of OralMedic Canada. He brought OralMedic to Canada after seeing firsthand how painful oral lesions affected many of his patients and finding that existing treatment options often fell short.
After interviewing a patient living with lupus, he realized that recurrent oral ulcers can be an especially significant burden for people with the disease. Since then, he has been working with Lupus Canada and other patient organizations to better understand patients’ experiences and help improve awareness and access to effective treatment.
