The Basics.

Canker sores, also called aphthous ulcers, are small, shallow lesions that develop on the soft tissues in your mouth or at the base of your gums. 20 ~ 30% suffer from recurrent episodes.

+ What is a canker sore?

Canker sores, also called aphthous ulcers, are small, shallow lesions that develop on the soft tissues in your mouth or at the base of your gums.

For those who suffer from recurrent episodes, such condition may also be characterized as Recurrent Aphthous Stomatitis or Sutton's Disease II.

+ Why do I get canker sores?

Many factors seem to predispose to or trigger attacks, but allergic reactions do not seem to be involved. Such factors include injury to the mouth, stress (for example, a college student may get canker sores during final exam week), and certain foods (particularly chocolate, coffee, peanuts, eggs, cereals, almonds, strawberries, cheese, and tomatoes). People with AIDS often have large canker sores that persist for weeks.

+ How common are canker sores?

Recurrent aphthous stomatitis (RAS) is very common. The cause is unknown, but the disorder tends to run in families. RAS usually begins in childhood, and 80% of people with RAS are < 30 years old.

+ What triggers/worsens canker sores?

Possible triggers for canker sores include:

- A minor injury to your mouth from dental work, overzealous brushing, sports mishaps or an accidental cheek bite
- Toothpastes and mouth rinses containing sodium lauryl sulfate
- Food sensitivities, particularly to chocolate, coffee, strawberries, eggs, nuts, cheese, and spicy or acidic foods
- A diet lacking in vitamin B-12, zinc, folate (folic acid) or iron
- An allergic response to certain bacteria in your mouth
- Helicobacter pylori, the same bacteria that cause peptic ulcers
- Hormonal shifts during menstruation
- Emotional stress

+ What are some diseases that could trigger canker sores?

Canker sores may also occur because of certain conditions and diseases, such as:

- Celiac disease, a serious intestinal disorder caused by a sensitivity to gluten, a protein found in most grains
- Inflammatory bowel diseases, such as Crohn's disease and ulcerative colitis
- Behcet's disease, a rare disorder that causes inflammation throughout the body, including the mouth
- A faulty immune system that attacks healthy cells in your mouth instead of pathogens, such as viruses and bacteria
- HIV/AIDS, which suppresses the immune system

+ What type of canker sore do I have?

Canker sores are often split into two categories:

Simple canker sores: they appear 3-4 times a year; they generally occur in people aged 10-20, and last about 1 week.

Complex canker sores: less common, larger, and more painful. They may last up to 1 month and leave a scar. Complex canker sores are often due to an underlying condition, such as a compromised immune system, Crohn's disease, or vitamin deficiency. Often, as one sore heals, it triggers another subsequent episode.

The Science.

Canker sores, also called aphthous ulcers, are small, shallow lesions that develop on the soft tissues in your mouth or at the base of your gums.

+ How do I know if I have Sutton's Disease II (major canker sores)?

The symptoms of Sutton disease II include red, painful ulcers that may appear on the tongue, the lining of the cheeks (buccal mucosa), floor of the mouth, and back of the throat (soft palate). Ulcers may develop in clusters or appear as single lesions scattered throughout the mouth. As many as 15 sores may be present at once. Individuals with Sutton disease II typically experience recurring episodes of mouth sores, usually with 2 to 3 sores during each attack.

The ulcers associated with Sutton disease II may vary in size. When the mouth ulcers associated with Sutton disease first erupt, they usually appear as red (inflamed) shallow erosions. Sores less than 1 centimeter in size are considered small or “minor” ulcers. These smaller sores are the most common form of the disease and usually last for 10 to 14 days. Smaller lesions do not usually leave scars. In some cases larger or “major” ulcers may develop lasting for weeks or months. Typically, these larger sores leave scars.

In severe cases, other symptoms of Sutton disease II may include a general feeling of weakness (malaise), fever, and swollen lymph nodes around the neck and head (lymphadenopathy).

+ Who are most likely to get major canker sores?

Sutton disease II affects more adult females than males. However, before puberty, males and females are equally affected. This disease occurs most frequently in malnourished children or adults whose immune systems are suppressed (i.e., by chemotherapy) or compromised (i.e., acquired immune deficiency syndrome).

+ What are some synonyms of Sutton's Disease II?

Unfortunately, recurring canker sores come in many names. Some of the names below are used to describe recurrent canker sores :

Aphthous Stomatitis, Recurrent
Aphthous Ulcer, Recurrent
Major Aphthous Ulcer
Major Canker Sore
Major Ulcerative Stomatitis
Periadenitis Mucosa Necrotica, Recurrent Type II
RAU
Recurrent Scarring Aphthae
von Mikulicz's Aphthae
Von Zahorsky's Disease

+ What's the difference between canker sores and cold sores?

Canker sores and cold sores are different conditions:

- Canker sores appear as white circles with a red halo; cold sores are normally fluid-filled blisters.
- Canker sores appear inside the mouth; cold sores appear outside the mouth- often under the nose, around the lips, or under the chin.
- Canker sores are not contagious; cold sores are caused by the herpes simplex virus (HSV) and, more rarely, HSV-2 (the genital herpes virus). Cold sores are contagious.

The Products.

Often people with recurrent canker sores have a family history of the disorder. This may be due to heredity or to a shared factor in the environment, such as certain foods or allergens.

+ What are some things I can do to prevent canker sores?

Watch what you eat. Try to avoid foods that seem to irritate your mouth. These may include nuts, chips, pretzels, certain spices, salty foods and acidic fruits, such as pineapple, grapefruit and oranges. Avoid any foods to which you're sensitive or allergic.

1) Choose healthy foods. To help prevent nutritional deficiencies, eat plenty of fruits, vegetables and whole grains.

2) Follow good oral hygiene habits. 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.

3) Protect your mouth. If you have braces or other dental appliances, ask your dentist about orthodontic waxes to cover sharp edges.

4) Reduce your stress. If your canker sores seem to be related to stress, learn and use stress-reduction techniques, such as meditation and guided imagery.

+ How do I use Dr.Canker products?

Great thing about Dr.Canker products is that you don't need to change your current lifestyle!

1) Brush your teeth as normal with Dr.Canker eco-friendly toothbrush.
Be sure to throw out the toothbrush every week as the soft bristle will eventually turn hard with each usage. Hard bristle can in turn damage your gum, thus creating higher likelihood of recurring canker sore episodes.

2) Use the Dr.Canker toothpaste. Dr.Canker toothpaste is specifically formulated to be extra gentle on your gums and is created without known irritating ingredients like Sodium Laurate. It's also designed with less taste and fragrance to reduce harmful chemicals that could trigger an episode of canker sores.

3) Use The Dr.Canker mouthwash to rinse your mouth after. Dr.Canker chlorhexidine mouthrinse is formulated to kill any canker sore-inducing bacteria like Helicobacter pylori yet designed to remain gentle. Give it a 15 second rinse with Dr.Canker mouthwash and rinse again with warm water after.

+ How long does it take before I see the effect of Dr.Canker?

Assuming you are using Dr.Canker products on a daily basis, it should take about 3 ~ 4 weeks before your mouth adjusts to the new products. Recurring episodes may occur but they should be less painful, heal much quicker and should not trigger further episodes once the initial sore starts healing.
