Canker Sores

What Are Canker Sores?

Minor Canker Sore

Canker sores, also known as aphthous ulcers, are non contagious, shallow ulcers that appear inside areas of the mouth. They are often accompanied by pain and can cause discomfort when chewing or talking. Canker sores look like small, yellow or white ulcers surrounded by red tissue that are typically found on the tongue, gums, or on the inside of lips. Oral sores are a common dental problem that typically heal within 1-2 weeks, but persistent sores that last longer than a couple of weeks may be the early stages of oral cancer.

Types of Canker Sores

Canker sores are seen in two major types which are categorized as:

  • Minor canker sores – Are small and typically heal in 1-2 weeks without treatment or scarring, can be accompanied by pain, and account for nearly 80% of all canker sores.
  • Major canker sores – Are larger and can take up to 6 weeks to fully heal. This type of canker score can leave hefty scarring, can be excruciatingly painful, and are far less common.
  • Herpetiform canker sores – Are super small in size, appear in patches with up to 100 sores, and heal in 1-2 weeks similarly to minor canker sores.

Canker Sores vs. Cold Sores

Canker & Cold Sores

Although these two types of canker soars are often confused, they are quite different. Unlike cold sores, canker sores only appear inside the mouth, are not contagious, and are not caused by the herpes virus. On the other hand, Cold sores , also known as fever blisters, appear outside areas of the lips or mouth and are highly contagious through touch.

Causes of Canker Sores

The specific cause of canker sores is not completely understood, but some of the possible causes are from:

  • Minor injury to oral tissues from things like: brushing teeth to hard, biting your cheek, braces or dentures, dental work, or a sports injury.
  • Foods that are high in acidity or spices can trigger or worsen a canker sore outbreak.
  • Food allergies or sensitivities can cause a canker sore outbreak.
  • Genetics. Canker sores may be hereditary or simply occur in people that live in the same environments, eat the same food, or have the same allergies.
  • Improper balance of nutrition intake that is lacking vitamin B-12, iron, zinc, or folate which is folic acid. These particular nutrients help you prevent the occurrence of canker sores.
  • Using dental hygiene products that contain sodium laurfyl sulfate has shown to increase the likelihood of developing canker sores.
  • Presence of certain bacteria in the mouth can trigger an allergic response that can cause canker sores.
  • Stress & smoking are both known to weaken your immune system response and can lead to an increased risk a canker sore outbreak.
  • Hormonal fluctuations can cause canker sores, as seen in women who are menstruating or during puberty.
  • Drugs including: Aspirin, NSAID’s, nicotine, certain antibiotics, immunosuppressants, antihypertensives, vasodilators, and protease inhibitors can cause canker sores.
  • Diseases including: Celiac disease, Crohn’s disease, Behcet’s disease, and HIV/AIDS are all associated with a higher risk of canker sore outbreak.

Canker sores can develop in any individual, but are more likely to occur and during the teen years and early adulthood. Canker sores are also more likely to develop in females than in males.

Symptoms of Canker Sores

Large Canker Sore

A number of symptoms may be present when you have a canker sore including:

  • Oval or circle-shaped white or yellow ulcers that appear in the mouth
  • Pain around the areas affected by the canker sore(s)
  • Red tissue surrounding the canker sores that may be sensitive or painful
  • Some individuals also experience a burning or tingling sensation in the area where a canker sore forms up to 24 hours before the sore appears.

There are a number of less common symptoms which may indicate a more serious dental infection or underlying cause and include:

  • Fever which typically indicates infection
  • Swollen lymph nodes which typically indicate infection
  • Physical sluggishness or feeling under the weather

Individuals who have a canker sore outbreak that is accompanied by any of the less common symptoms should see a doctor to ensure there is not a more serious infection or issue.

Treatments for Canker Sores

Most canker sores will heal in 1-2 weeks time without requiring treatment. There are some home remedies that you can use to try to relieve the pain or discomfort caused by canker sores which include:

  • Brushing your teeth with care as to avoid aggravation of canker sores from contact with toothbrush bristles.
  • Avoiding the use of toothpaste or mouthwash that has lauryl sulfate.
  • Drinking cold fluids or dissolving ice in your mouth. The coldness can numb the canker sore and ease pain, but in some cases, the cold fluid touching the sore can cause sharp pain.
  • Rinsing your mouth with a salt + water mix can help relieve pain from canker sores.
  • Rinsing your mouth with a mixture of milk of magnesia and Benadryl can help with canker sores. Dabbing milk of magnesia directly on the sore with a cotton swap can also be effective.
  • Over-the-counter pain relievers such as NSAID’s like asirin or ibuprofen. DO NOT take aspirin if you are under the age of 20 or are already bleeding.
  • Applying topical medications directly to the canker sore such as benzocaine or lidocaine can help relieve the pain or discomfort.

Prevention of Canker Sores

Since canker sores have many potential causes, it can be hard to understand what to avoid to prevent them from happening in the future. Reduce your risk of encountering canker sores by:

  • Relaxation helps avoid bruxism.Avoid foods and actions that irritate the inside of your mouth or have triggered an outbreak in the past. This can include avoiding eating acidic or spicy foods, using a soft bristled toothbrush to avoid irritation while brushing, and avoiding habits such as smoking tobacco or drinking alcohol.
  • Ensure that your diet has a proper balance of: B-12, iron, zinc, and folic acid. These nutrients provide support for your body that can help prevent future canker sores.
  • Reduce your stress levels. Stress negatively impacts the function of your immune system, and avoiding or reducing it can help prevent canker sores from developing.

Seek medical help with your canker sores if you experience:

  • Canker sores that do not heal within 3 weeks
  • Uncommonly larger canker sores
  • Persistent, severe pain that is not responding to pain relievers
  • Canker sore that are spreading or popping up faster than they are disappearing
  • Fever or any other signs of infection
  • Difficulty in eating or drinking

I have had a lot of procedures including 8 implants. There is no better dentist office than Carson and Carson. Dr. Derek Carson (the son of Dr. Leroy Carson) is FANTASTIC! He has learned well from his father (who still works there). Papa is the MAN!, and has been for years. Insane amount of knowledge. The Doctors are THE BEST! The support staff is fun and professional always. I will never go anywhere else.

Excellent service. Dr. Derek was the only emergency oral surgeon to respond, everything was done so fast and without pain. Highly recommended, Carmen is his amazing front office manager, she is highly professional and knowledgeable. I had very painful broken wisdom tooth removed. I can honestly say I have waited longer at the Starbucks Drive thru. Thank you!!!
