Oral ulcers, Stomatitis, Mouth ulcers, Crohn’s disease, and coeliac disease.
Root Cause of Disease
In many cases, the reason for mouth ulcers is unclear. Most single mouth ulcers are caused by damage to the lining inside of the mouth. For example:
- Accidentally biting the inside of your cheek or a sharp tooth
- Poorly fitting dentures
- Hard food
- A defective filling
Symptoms
The symptoms of a mouth ulcer depend on the cause, but may include:
- One or more painful sores on part of the skin lining the mouth.
- Swollen skin around the sores.
- Problems with chewing or tooth brushing because of the tenderness.
- Irritation of the sores by salty, spicy, or sour foods.
- Loss of appetite.
Aphthous ulcers generally occur on the softer mouth lining of the lips, cheeks, sides of the tongue, floor of the mouth, back of the roof of the mouth, and around the tonsil area. These ulcers are usually no larger than 5mm. You may develop more than one aphthous ulcer at a time, and sometimes these ulcers are joined together.
Causes
Mouth ulcers can be caused by a wide range of factors including:
- Accidentally biting the inside of your cheek.
- Injury from a toothbrush (such as slipping while brushing).
- Constant rubbing against misaligned or sharp/broken teeth.
- Constant rubbing against dentures or braces.
- Burns from eating hot food.

When to seek treatment for mouth ulcers?
If ulcers interfere with your normal daily activities or have persisted for 2 weeks, see your dentist or an oral medicine specialist. In some cases, you may need blood tests if it’s suspected that you have an underlying deficiency (such as iron, folate, or vitamin B deficiency) or an inflammatory condition.
If your oral health professional can’t determine the cause of your mouth ulcers, or if the ulcers don’t respond to normal treatments, you may need to have a biopsy of part of the ulcer and some of the surrounding tissue. A biopsy is a procedure where a tissue sample is taken for examination and diagnosis.
