What causes those tiny little lesions in our mouths that often appear out of nowhere?
Unfortunately, doctors have not been able to pinpoint the exact cause of canker sores, but there is reason to believe that certain types of bacteria and/or viruses are responsible. Unlike cold sores, they are not related to the herpes simplex virus.

Here’s what we do know. Canker sores can be caused by:
- Mouth injuries. Accidentally biting the inside of the cheek or lip may also result in a canker sore.
- Burns. Temperature hot food or drink may cause a canker sore in an area of the mouth.
- Irritation. Spicy and/or acidic foods often produce a canker sore as a response to the irritation these spices and acids create in the mouth. Chewing tobacco is also known to cause irritation and subsequent canker sores.
- Poor-fitting dentures. A canker sore may form in the area of the mouth where the denture is constantly rubbing.
- Orthodontics. Brackets, bands, and various other orthodontic attachments will often cause canker sores to develop in area of the mouth where there is constant friction.
- Vitamin deficiency. Deficiencies in vitamin B12, foliate (folic acid), and iron, may trigger canker sore development.
- Bacteria responsible for peptic ulcers known as Helicobacter pylori has been linked to canker sores.
- Stress and hormonal changes may also trigger canker sores.
No one. Anyone can get a canker sore at any time. Although, women statistically suffer from canker sores more often than men.
Treatment is not necessary for most canker sores as they tend to heal quickly on their own. If canker sores persist for longer than 2 weeks, give us a call as an underlying problem may be brewing inside your mouth.
