Are Canker Sores Contagious?

Are canker sores contagious? Dr. Angela Walk

Have your ever had a painful sore in your mouth that just doesn't seem to go away? Does it cause burning and tingling while eating certain foods and even with talking?

That sounds like a troublesome canker sore. As a natural physician, I am often asked about health concerns and how to address them naturally. I have recently had more patients ask, are canker sores contagious?

Contrary to what a lot of people might think, canker sores are NOT contagious and can resolve themselves within a week or two. There is no person-to-person spread. So, you can safely kiss your partner if it's not too painful!

Addressing canker sores naturally is the most effective way to rid yourself of these pesky sores. Natural treatments such as essential oils, proper nutrition, and natural supplements can help to shorten the duration, diminish the pain, and prevent recurrence.

Now that you know that they are not contagious, let's look at what they are, what causes them, and how to get rid of them.

What Are Canker Sores?

What causes canker sores? Dr. Angela Walk

Canker sores are small lesions or ulcers that are found in the mouth at the base of our gums, on the tongue, cheek lining, and inside the lips.

What Are The Symptoms Of Canker Sores?

  • Burning or tingling sensation in the mouth a day prior to the appearance of a sore

  • A small, white or yellow oval-shaped ulcer with a red border

  • Painful or tingling area in the mouth.

  • Pain with eating or drinking certain foods or drinks

  • With more severe or complex canker sores, patients can experience swelling of the lymph nodes, fatigue, or fever

What Causes Canker Sores?

What causes canker sores? Dr. Angela Walk

Canker sores affect 20% of people and women get canker sores more often than men. The most common factors that cause canker sores are increased times of emotional stress, a minor injury to the inside of the mouth, or eating acidic foods or hot, spicy foods.

Take a look at these other common causes:

  • Accidentally biting your cheek or lip

  • A minor injury from dental work or dental equipment such as braces or poorly fitting dentures

  • Cleaning teeth too abrasively

  • Toothpastes and mouthwashes that contain the ingredient Sodium Lauryl Sulfate

  • Food sensitivities, especially acidic and spicy foods

  • Nutritional deficiencies - canker sores are seen more often in patients with nutritional deficiency in vitamin B-12, zinc, folic acid or iron

  • More severe or complex canker sores are seen in patients with autoimmune disorders such as Inflammatory Bowel Diseases (celiac disease, ulcerative colitis and Crohn’s disease), Lupus, Rheumatoid Arthritis, and AIDS.

  • Hormonal shifts during the menstrual cycle

  • Increased times of emotional stress

Canker Sores vs. Cold Sores

Canker sores should not be confused with cold sores or fever blisters. Canker sores may resemble cold sores/fever blisters, but they are not the same. Cold sores or fever blisters are caused by HSV (Herpes Simplex Virus). These are contagious blisters, making their appearance on the lip area or outside the oral cavity. Canker sores are not caused by a virus and therefore are NOT contagious.

Are Canker Sores A Virus?

No, canker sores are not caused by a virus and therefore are NOT contagious.


Natural Remedies For Canker Sores


How To Get Rid Of Canker Sores Fast!

The most effective way to manage canker sores is with natural remedies. Canker sores often recur, but you can reduce their frequency, and ease the discomfort by following these tips:

What Toothpaste Causes Canker Sores?

What toothpaste causes canker sores? Dr. Angela Walk

Conventional toothpaste contains sodium lauryl sulfate, SLS, a chemical compound that functions as a foaming agent in many personal care and home care cleaning products including toothpaste.

If you have recurring canker sores, tossing out your traditional toothpaste is critical. SLS offers no real value and can be harmful to the protective lining in the mouth. SLS-free toothpaste will still offer the necessary cleaning benefits, yet without the harmful ingredients.

What Foods Cause Canker Sores?

What foods cause canker sores? Dr. Angela Walk

Avoid eating abrasive, spicy, or acidic foods. Abrasive foods include crackers, chip, nuts, pretzels or burnt toast. Also avoid acidic foods such as lemons, oranges, orange juice, tomatoes, strawberries, coffee, and sodas. Spicy foods such as hot sauce can also create further irritation.

Can Poor Oral Hygiene Cause Canker Sores?

Regular brushing after meals and flossing once a day can keep your mouth clean and free of foods that might trigger a sore. Use a soft brush to help prevent irritation to delicate mouth tissues, and avoid toothpastes and mouth rinses that contain sodium lauryl sulfate.

Can Stress Cause Canker Sores?

One of the most common causes of canker sores is increased emotion stress. The more stress we experience in our lives, the more health challenges we will have. Make time to practice those things that manage your stress levels.

Exercise, mental health walks, meditation, time out with your friends, playing in the dirt, reading...whatever works for you.

According to Mayo Clinic, reducing stress in your life as much as possible is actually a key canker sore natural treatment. This lifestyle change can help to prevent canker sores since stress reduction is such an overall immune system and health booster.

Can Lack of Sleep Cause Canker Sores?

This goes a long way in helping reduce stress and allowing your body to heal properly. We all need 7-8 hours of sleep per night for proper health and immune strength. Try our Sleep Assist Essential Oil Blend or one of our premium melatonin supplements for a more restful, restorative sleep.

Does Oil Pulling Help Canker Sores?

Does oil pulling help canker sores? Dr. Angela Walk

Oil pulling is swishing coconut oil in your mouth, without swallowing, for 10-15 minutes. Coconut oil has antibiotic and anti-inflammatory properties that will help with your overall oral health (not just with canker sores). This is one of the most effective practices to get rid of canker sores.

The coconut oil acts as a disinfectant and cleanses your mouth of harmful bacteria. You can also add a few drops of essential oils to further cleanse your mouth. Clove and tea tree are the most effective.

What Is The Best Pain Reliever For Canker Sores?

What is the best pain reliever for canker sores?

Use an Organic, Topical Solution to numb the pain, shorten the duration, and prevent recurrence.

There are many other remedies floating around for the treatment of canker sores, but they aren’t all safe to use (putting alum directly on the canker sore, for example).

Avoid products and numbing creams that contain harmful, synthetic chemicals that can be toxic to your skin and mouth.

This is the product I craft and recommend for eliminating canker sores fast. It includes only organic, clean, green ingredients and organically grown essential oils of clove, lavender, peppermint, eucalyptus, and tea tree.

Are Canker Sores A Sign Of A Weak Immune System?

Those who have a poorly functioning immune system are more prone to having canker sores. See below for my recommendations on necessary supplements to boost immune strength.

What Supplements Are Good For Canker Sores?

What supplements are good for canker sores? Dr. Angela Walk

Certain nutritional deficiencies can lead to having more canker sores. The most common deficiencies are vitamin B12 and Zinc. Studies have shown that supplementing with these support the immune system and prevent the recurrence of canker sores.

Is Vitamin B 12 Good For Canker Sores?

Low levels of vitamins B12 was found in one study to be linked to recurrent mouth ulcers. Other research has found supplementation with 1000mcg vitamin B12 reduced the severity and duration of recurrent mouth ulcers in 75% of subjects who took the supplement.

B12 helps promote faster recovery and reduced pain from canker sores. It also improves energy and helps eliminate fatigue and exhaustion.

I recommend our B-Replete because it is a comprehensive supplement of B Vitamins that includes B12 and B6 and helps to improve immune function significantly. When the immune system is under attack, it’s important to include a vitamin B supplement.

Are Probiotics Good For Mouth Ulcers?

I believe the single most important thing people can do to improve their health and immune response is to heal their gut. Probiotics maintain the proper balance of bacteria in your digestive system.

The best way to get probiotics is with fermented foods like kefir, sauerkraut, kombucha, fermented vegetables, and apple cider vinegar. However, if you don't eat fermented foods, a good quality probiotic is the best solution.

Can Zinc Deficiency Cause Canker Sores?

Zinc plays a role in immune function because it is an essential component of many enzymes which are involved in the development of immune cells. Taking a zinc supplements has been shown to reduce canker sores by between 50 to 100 percent and can keep you from getting them in the first place.

Melatonin For Sleep Support

Getting adequate amounts of quality sleep is important for relieving stress and healing from any type of illness. Achieving adequate quality sleep may not be the easiest if you’re under stress, which in turn could worsen its severity.

Melatonin is a natural hormone that regulates your body’s circadian rhythm, or sleep-wake cycle. Supplementing with melatonin may help you fall asleep faster and stay asleep longer. I recommend melatonin in liquid form. This one is lemon flavored. Yum!

Ashwaghanda For Stress Support

Yes, stress is one of the most common causes of canker sores. For stress reduction, I recommend ashwaghanda. It is an adaptogenic herb native to India, where it has been used in Indian Ayurveda, one of the world’s oldest medicinal systems.

According to studies, supplementing with ashwaghanda was strongly associated with greater reductions in stress, anxiety, and depression. Ashwaghanda was also linked to a 23% reduction in morning levels of cortisol, a stress hormone.

What Are The Best Essential Oils for Canker Sores?

Is clove essential good for canker sores? Dr. Angela Walk

Essential oils have enhanced lives for thousands of years with their powerful medicinal properties. They have plant based intelligence that seeks imbalances in the body to support health and have been used successfully with numerous mouth & skin conditions.

Essential oils provide antibacterial and antiseptic properties that aid in the healing of canker sores.

Is Clove Essential Oil Good For Canker Sores?

Cloves have been used for many years as a natural analgesic to relieve mouth pain and toothaches. Clove essential oil also has an antioxidant (ORAC) score of over 1,000,000! So, this is definitely an oil you’ll want to consider for supporting your entire body and especially canker sores.

Can Tea Tree Oil Heal Canker Sores?

Tea Tree offers strong anti-viral support and can significantly shorten the duration of canker sores. It has anti-inflammatory and antimicrobial properties and has strong wound healing properties.

Is Lemon Balm Good For Canker Sores?

Lemon balm has been studied extensively for it's ability to actually reduce pain from canker sores. It even outperformed other traditional topical remedies that are typically recommended for canker sore pain.

Is Cinnamon Oil Good For Mouth Sores?

Cinnamon oil has many health benefits to aid in the healing of canker sores. It has powerful anti-inflammatory properties that immediately begin to reduce the swelling.

Can Oregano Oil Help Canker Sores?

Oregano oil contains a polyphenol which acts as a potent antibacterial. It also boosts your immune system function.

As a wellness physician, I have consulted my patients for years regarding the use of essential oils for skin challenges and immune support. I handcraft proprietary essential oil blends and organic body care products to address such concerns.

I use these 5 essential oils in my Canker Elimin-X oral mouth solution that also contains coconut oil, aloe vera & sweet almond oil. We've taken the guesswork out of combing natural ingredients and essential oils to resolve canker sores and prevent recurrence.
