Mouth Ulcer Types: Understanding the Different Varieties

Mouth ulcers, also known as canker sores or aphthous ulcers, come in various types, each with distinct characteristics and potential causes. Understanding these different types can help in identifying the most appropriate treatment and management strategies. Here's an overview of the main types of mouth ulcers:

Minor Aphthous Ulcers:

These are the most common type, accounting for about 80% of all mouth ulcers. Characteristics include:

Small, round or oval sores

Usually less than 5mm in diameter

Heal within 7-14 days without scarring

Often occur on the inside of the cheeks, lips, or tongue

Major Aphthous Ulcers:

Less common but more severe than minor ulcers, these are characterized by:

Larger size, often exceeding 10mm in diameter

Deeper and more painful than minor ulcers

Can take several weeks to heal and may leave scars

Often appear on the lips, soft palate, or back of the throat

Herpetiform Ulcers:

These are the least common type of recurrent aphthous ulcers and are not related to herpes virus infections despite their name. Features include:

Multiple, small (1-3mm) ulcers that may merge into larger, irregular sores

Can occur in clusters of up to 100 ulcers at a time

Typically heal within 7-10 days

Most commonly affect women and tend to develop later in life

Traumatic Ulcers:

These are caused by physical injury to the mouth and are characterized by:

Irregular shape corresponding to the injury

Often occur after accidentally biting the cheek or tongue

Usually heal within a few days once the source of irritation is removed

Viral Ulcers:

Caused by viral infections, most commonly the herpes simplex virus. These include:

Cold sores (herpes labialis): typically appear on the lips or around the mouth

Intraoral herpes: can occur inside the mouth, usually on the gums or hard palate

Tend to start as small blisters that rupture into ulcers

Nutritional Deficiency Ulcers:

These can result from deficiencies in vitamins or minerals, particularly:

Vitamin B12 deficiency

Iron deficiency

Folate deficiency

Characteristics may vary but often include persistent or recurrent ulcers.

Systemic Disease-Related Ulcers:

Various systemic conditions can cause mouth ulcers, including:

Beh?et's disease: recurrent, painful ulcers in the mouth and genitals

Inflammatory bowel diseases (Crohn's disease, ulcerative colitis): can cause oral ulcers as an extraintestinal manifestation

Celiac disease: may present with recurrent aphthous ulcers

Medication-Induced Ulcers:

Certain medications can cause or exacerbate mouth ulcers, including:

Nonsteroidal anti-inflammatory drugs (NSAIDs)

Beta-blockers

Nicorandil (used for angina)

<ol start=”9”>

Chemotherapy-Induced Ulcers:

Cancer treatments can lead to oral mucositis, characterized by:

Widespread, painful ulceration throughout the mouth

Can be severe and interfere with eating and drinking

Autoimmune-Related Ulcers:

Conditions like lupus or pemphigus can cause mouth ulcers as part of their symptomatology.

Identifying the specific type of mouth ulcer is crucial for proper management. While most minor ulcers can be treated with over-the-counter remedies, persistent, severe, or recurrent ulcers may require professional medical evaluation to determine the underlying cause and appropriate treatment.
