Youre also at risk for canker sores if you have a gluten intolerance or a gluten allergy , or other food allergies. But its important to note that canker sores arent always caused by food, notes Jennifer Silver, DDS, who is based in Calgary, British Columbia.

These types of lesions can also run in families. So if your mother or father are prone to canker sores, you may be, too.

Additionally, emotional stress and hormonal shifts can be culprits, as well as autoimmune diseases or conditions that cause inflammation, such as Crohns disease, Behcets disease, and HIV or AIDS.

Mouth Ulcerswhy We Get Them

Dental|July 25, 2018| Author: Naturopath


Did you know reoccurring attacks of mouth ulcers is a sign of nutritional deficiencies or food sensitivities? While these painful sores in the mouth are annoying at times they could be trying to tell you what might be lacking in your diet. Mouth ulcers can also be triggered by stress, infection and even if you accidently bite your cheek. So, what exactly are mouth ulcers and what can we do to fix them?

Allergies Versus Oral Health

While allergies can result in tingly or swollen lips, mouth, or tongue and irritated gums, the most common way seasonal allergies can become a problem for oral health is dry mouth. Whenever we have congestion, we end up breathing through our mouths instead of our noses, which dries up our saliva. Having dry mouth presents a serious threat to oral health because saliva is the mouths first line of defense against gum disease and tooth decay.

Toothpaste And Mouthwashes Can Irritate Your Mouth

Toothpastes and mouthwashes help maintain oral health by removing plaque from your teeth and freshening your breath. But if your oral hygiene products contain sodium lauryl sulfate , you may develop a canker sore if youre sensitive to this ingredient.

A review published in March 2017 in the journal Clinical and Aesthetic Dermatology noted that in a trial conducted among patients using SLS-free products and a control group, the SLS-free products didnt reduce the occurrence of sores, but did positively affect the healing process.

If you have a history of canker sores, check the ingredient label of your oral products. Choose toothpastes and mouthwashes that dont contain this ingredient, and then monitor your condition for improvement.

Food Sensitivity Or Allergy

Thats right certain foods may make your tongue hurt. You may have whats called oral allergy syndrome. This condition is also known as pollen-food syndrome, and its most often caused by raw fruits, vegetables, and certain tree nuts.

Along with a sore tongue, you might experience:

  • an itchy mouth
  • a scratchy throat
  • swelling of your lips, mouth, or tongue

Oral allergy syndrome is more likely to start in older children, teens, and younger adults. If your reaction is severe, your doctor may suggest you carry an epinephrine auto-injector.

Smoking and even stopping smoking can cause tongue pain. When you smoke, you also put yourself at a higher risk of developing cancer in your mouth and throat.

Other issues smoking can cause in your mouth include:

  • stained teeth
  • muscle weakness
  • numbness or tingling in your hands and feet

Vitamin deficiencies generally develop over a long period of time anywhere from several months to years. Treatment involves eating a well-balanced diet, taking supplements, and sometimes receiving vitamin injections.

Recurrent Mouth Sores And Burning Mouth Syndrome

Frederick R. Jelovsek MD, MS

“Why do we get mouth sores? I get them on my tongue and under as well as on the inside of my mouth.”

“I am 40, normal menstrual history. Meds I’m on are Orthocept® for birth control, Celexa®, an antidepressant, and Zyrtec® for allergies.”


Mouth sores are sometimes called apthous ulcers or apthous stomatitis when the cause is not known but thought to be allergic or immune in origin. About 15-20% of the population complains of recurrent mouth sores at various times .

I am glad you included your medications because many times these sores are caused by prescribed or over-the-counter medications. Of the medicines you list, none are known for a high incidence of mouth ulcers except anti-depressants which can have a drying effect on the mouth. All of your mediciations have had a very small incidence of this problem reported. The Zyrtec® can produce a pharyngitis and both Zyrtec® and Celexa® have about a 20% incidence of dry mouth. It is possible that a lack of saliva makes you more susceptible to the mouth sores from some other ingested food or drink.

The list of causes of mouth sores is quite long . In general, however, you should look for direct contact irritants or allergens, immune skin conditions and infectious agents.

Contact irritants/allergens can include:

  • acidic foods like colas, juices, coffee
  • spicy foods, eg., cinnamon
  • tobacco
  • lichen planus
  • Behcets disease
  • periadenitis mucosa necrotica recurrens

Who Gets Contact Stomatitis And Why

Contact stomatitis is a delayed hypersensitivity reaction to a chemical in contact with the lining of the mouth. It occurs in people already sensitised to the allergen. However, it is quite uncommon compared to contact allergic dermatitis or contact cheilitis, probably because:

  • Saliva constantly flushes the mouth so chemicals are diluted and do not stay in contact with the mucosa for very long
  • There is a good blood supply to the lining of the mouth meaning any chemical absorbed through the mucosa is quickly removed from the area
  • The lining of the mouth is not well keratinised so chemicals are less likely to bind to keratinprotein to form an allergen.
  • Rarely, contact urticaria may present as stomatitis.

    Treatment And Lifestyle Tips

    What Causes a Sore Throat?

    There are no standard treatments for oral allergy syndrome other than avoiding specific foods that are associated with allergy symptoms. Careful management of diet can ensure that people with the syndrome can lead otherwise normal lives. People with oral allergy syndrome should explain the condition to others to help them understand what foods are off-limits.

    In the event of an allergic reaction, initial treatment generally involves rinsing the mouth with water and then resting. Hot drinks can also destroy some proteins, and so inactivate them.

    Antihistamines typically take 1-2 hours to work, while the effects of oral allergy syndrome typically start to wear off after about 30 minutes. However, an antihistamine can prevent effects from lingering and should be taken as soon as the reaction occurs.

    In some cases, it may be possible to make the immune system less sensitive to the allergen through immunotherapy or allergy shots. This is especially useful when a single allergen is involved. Under-the-skin delivery of immune therapy is currently

    Canker Sores A Sign Of Gluten Sensitivity

    These canker sores can be associated with conditions that affect the GI tract, immune defects and syndromes that are inflammatory. They are not infectious or contagious in any way. However up to 20% of patients with RAS are deficient in iron, vitamin B and folic acid. Another 3% have malabsorption or GI disorders. The detergent sodium lauryl sulphate found in toothpastes may aggravate them. And NSAIDs and other drugs can cause them.

    They found 247 patients with RAS and screened them with the IgA anti-endomysial antibody test along with serum IgA and IgA anti tissue transglutaminase. Seven patients with at least one positive test then had duodenal biopsies and all were found to have gluten sensitive enteropathy. This explained why these 7 patients were not successfully treated with the usual anti-canker sore medications . Over the next six months, 4 of the patients that went on a strict gluten free diet improved greatly.

    How Do You Get A Canker Sore After Exposure To A Allergen Source

    Your immune system regards the food substance as foreign material which can be dangerous for your body and triggers a series of reactions to form immune cells against them, which release histamine. This can cause the clinical symptoms of inflammation, irritation and itching. However, in your fragile and sensitive oral cavity there can be direct cellular or tissue damage leading to the break-up of the intact skin which allows the oral ulcers to appear. The pain associated is due to the exposed free nerve endings of the skin which get damaged by slightest of physical or chemical insult.

    How Is Contact Stomatitis Diagnosed

    The diagnosis of contact stomatitis is mainly clinical, based on history and examination. Investigations may be done to exclude other possible diagnoses and to try to identify the responsible allergen.

    A mucosalbiopsy may be required to exclude other conditions such as various forms of oral leukoplakia, trauma, oral candidiasis , oral lichen planus and oral lichenoid drug eruption, lupus erythematosus or discoid lupus, or oral cancer. The histology of contact stomatitis itself is nonspecific. However, the presence of many plasma cells may be suggestive of a contact allergy.

    The likely source of the allergen will often be identified on the history and examination with improvement when the source is avoided. Recurrence of the stomatitis following rechallenge with the allergen confirms the cause. Patch testing, including with the patients own products, may be helpful in identifying the responsible allergen but false negatives are common. The relevance of a positive patch test reaction must be assessed in the clinical setting.

    Drugs And Radiation Therapy

    The most common drugs causing mouth sores include certain cancer chemotherapy drugs. Drugs containing gold, which were once used to treat rheumatoid arthritis and some other autoimmune disorders, can also cause mouth sores, but these drugs are rarely used because safer and more effective drugs are now available. Radiation therapy is also a common cause of mouth sores. Rarely, people may develop mouth sores after taking antibiotics.

    Natural remedies for canker sores

    Canker sores usually appear as round, painful open sores that have a white or yellowish coating and a red “halo” around them. Most are small and shallow, but occasionally can be larger and deeper.

    Most often, canker sores pop up alone, but they can appear in small clusters. Sometimes an area will tingle or burn before a canker sore actually develops.

    It takes about 2 weeks for canker sores to heal. During this time, the sores can be painful, although the first 3 to 4 days are usually the worst. Unless they are very large or deep, they usually heal without scarring.

    What Causes A Canker Sore

    The cause of canker sores is unknown, but they tend to run in families. Canker sores are not contagious.

    Canker sores may also develop when you:

    • Are stressed or tired.
    • Have your menstrual cycle, if you are a woman.
    • Hurt your mouth, such as biting your lip.
    • Have braces on your teeth.
    • Have food allergies. Eating foods that you are allergic to may cause you to get a canker sore.
    • Eat or drink food or juice that has a lot of acid, such as orange juice.
    • Do not get enough vitamins or minerals in your diet, such as iron, vitamin B12, and folic acid.

    How Is Contact Stomatitis Treated

    The most important treatment for contact stomatitis is the avoidance of the allergen. If it is due to a flavouring or preservative in food or dental hygiene products, the patient should be advised to stop using the product. It may take up to 2 weeks for complete resolution. A topical steroid application may be required for persistent, severe or chronic reactions.

    In one case due to an acrylic monomer in a new denture, prolonged boiling of the denture resulted in full curing of the acrylate and the stomatitis resolved.

    When the contact stomatitis is due to a dental restoration or orthodontic device , replacement of the restoration or device may be considered if the stomatitis reaction is clearly related by site to the restoration/device and a positive patch test to the metal has been shown.
