Understanding Mouth Ulcers: Appearance, Causes, and Treatment

Mouth ulcers, also known as canker sores or aphthous ulcers, are small, painful lesions that develop on the soft tissues inside the mouth, including the lips, cheeks, tongue, and gums. These common oral sores can be uncomfortable and sometimes make eating, drinking, or speaking difficult. Understanding what mouth ulcers look like and their characteristics can help you identify them and seek appropriate treatment if necessary.

Appearance of Mouth Ulcers:

Mouth ulcers typically appear as round or oval-shaped sores with a white, yellow, or grayish center surrounded by a red border. They can vary in size, ranging from a few millimeters to about a centimeter in diameter. In some cases, multiple ulcers may appear at once, causing more discomfort.

The most common types of mouth ulcers include:

Minor aphthous ulcers: These are the most prevalent type, measuring less than 1 cm in diameter and usually healing within 7-14 days without scarring.

Major aphthous ulcers: Larger and deeper than minor ulcers, these can be over 1 cm in diameter and may take several weeks to heal, sometimes leaving a scar.

Herpetiform ulcers: These appear as clusters of tiny ulcers, often merging to form larger, irregular sores.

Causes of Mouth Ulcers:

The exact cause of mouth ulcers is not always clear, but several factors can contribute to their development:

Minor injuries to the mouth, such as accidental bites, brushing too hard, or irritation from dental appliances

Stress or anxiety

Hormonal changes, particularly in women during menstruation or pregnancy

Nutritional deficiencies, especially in vitamin B12, iron, or folic acid

Certain foods, like citrus fruits, tomatoes, or spicy foods

Weakened immune system

Genetics, as some people are more prone to developing mouth ulcers

Certain medical conditions, such as celiac disease, inflammatory bowel disease, or HIV/AIDS

Differentiating Mouth Ulcers from Other Oral Conditions:

It's important to note that not all sores in the mouth are ulcers. Other conditions that may cause similar symptoms include:

Cold sores: Caused by the herpes simplex virus, these typically appear on the outer lips and are contagious.

Oral thrush: A fungal infection that causes white patches on the tongue and inner cheeks.

Oral cancer: While rare, persistent sores that don't heal should be evaluated by a healthcare professional.

Treatment and Management:

Most mouth ulcers heal on their own within a week or two. However, there are several ways to manage symptoms and promote healing:

Over-the-counter topical treatments containing benzocaine or lidocaine to provide pain relief

Antimicrobial mouthwashes to prevent infection and reduce inflammation

Avoiding spicy, acidic, or rough-textured foods that may irritate the ulcer

Applying a small amount of milk of magnesia to the ulcer to soothe discomfort

Using a soft-bristled toothbrush and gentle oral care techniques

Rinsing with warm salt water to help cleanse and soothe the affected area

When to Seek Medical Attention:

While most mouth ulcers are harmless and resolve on their own, you should consult a healthcare professional if:

Ulcers persist for more than three weeks

They are unusually large or painful

You experience frequent recurrences

The ulcers are accompanied by other symptoms like fever or swollen lymph nodes

In conclusion, understanding what mouth ulcers look like and their characteristics can help you identify them and take appropriate action. While they can be uncomfortable, most mouth ulcers are benign and will heal on their own with proper care and management.
