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.



Eco-friendly, extra soft bristle designed to be used and thrown away every week.

Continuous usage will harden the bristle of the toothbrush, damaging the gums and making it susceptible to canker sores.






Toothpaste specifically formulated for the sensitive without the known, irritating compounds like Sodium Lauryl Sulfate & overly strong minty fragrances + high level of Xylitol that eliminates the plaque that often trigger canker sores.



Chlorhexidine mouthrinse formulated to reduce any canker sore-inducing bacteria like Helicobacter Pylori while remaining gentle to the gums.




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

+ How common are canker sore?

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.

+ How do I know if I have Sutton's Disease II (Major Canker Sores)?

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. 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. 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.

+ 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 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.
