What are mouth ulcers

Mouth ulcers, also known as canker sores, are small, painful lesions that develop inside the mouth, typically on the inside of the cheeks, lips, or on the tongue. These ulcers are often round or oval-shaped and can be white, yellow, or gray in color, with a red border around them. While mouth ulcers are usually harmless, they can be uncomfortable and may interfere with eating, drinking, and speaking.

Causes of Mouth Ulcers.

Injury or trauma: Biting the inside of your cheek or brushing your teeth too hard.
Stress: Emotional stress is a common trigger for mouth ulcers.
Dietary deficiencies: Lack of vitamins, particularly B12, folic acid, and iron, can contribute to ulcer formation.
Hormonal changes: Women may experience mouth ulcers due to hormonal fluctuations, especially during menstruation.
Underlying health conditions: Certain conditions like celiac disease, Crohn's disease, or an impaired immune system may make you more prone to developing ulcers.

Symptoms of Mouth Ulcers.

The main symptom of a mouth ulcer is a small, painful sore inside the mouth. Other symptoms can include:
Sensitivity to spicy, salty, or acidic foods.
Swelling or redness around the ulcer.
A tingling or burning sensation before the ulcer appears.

Types of Mouth Ulcers.

Understanding the different types can help in identifying the best course of treatment. Below are the most common types of mouth ulcers:

Minor Mouth Ulcers.

Minor mouth ulcers are the most common type and typically affect the inside of the lips, cheeks, or tongue. They are small, usually less than 1 cm in diameter, and have a round or oval shape. These ulcers are typically not too painful and generally heal within 7 to 14 days without scarring.
Characteristics:
Size: Small (less than 1 cm)
Shape: Round or oval
Healing time: 7-14 days
Pain level: Mild to moderate

Major Mouth Ulcers

Major mouth ulcers are larger and deeper than minor ones. They can be more painful and may take longer to heal, sometimes up to 6 weeks. These ulcers are typically over 1 cm in diameter and can cause significant discomfort. They may also leave scars after healing. Major mouth ulcers are often associated with underlying health conditions.
Characteristics:
Size: Larger than 1 cm
Shape: Irregular or round
Healing time: Several weeks (up to 6 weeks)
Pain level: Severe

Herpetiform Mouth Ulcers

Herpetiform mouth ulcers are small, numerous, and can occur in clusters. They are often grouped together, forming a larger area of sores. Although their appearance may resemble cold sores (herpes simplex), they are not caused by the herpes virus. Herpetiform ulcers can be very painful and may take 1 to 2 weeks to heal.
Characteristics:
Size: Small (less than 1 cm)
Shape: Clustered, irregular
Healing time: 1-2 weeks
Pain level: Moderate to severe

4. Secondary Mouth Ulcers

Secondary mouth ulcers occur as a result of another medical condition or trauma. They are often caused by infections, certain medications, or underlying health conditions such as Crohn’s disease, celiac disease, or HIV/AIDS. Secondary ulcers may not heal as quickly and may recur frequently if the underlying condition is not managed.
Characteristics:
Caused by infections or health conditions
Can be painful and persistent
May require treatment for the underlying cause

5. Trophic Mouth Ulcers

Trophic ulcers are a rare type of mouth ulcer that result from nerve damage or conditions affecting the nerves. These ulcers are usually larger and deeper than minor ulcers and may take longer to heal. They are commonly seen in individuals with neurological conditions or long-term use of medications that affect the nervous system.
Characteristics:
Caused by nerve damage
Larger and deeper than minor ulcers
Persistent and difficult to heal

How to Treat Mouth Ulcers

Although mouth ulcers typically heal on their own within one to two weeks, there are several ways to ease the pain and speed up recovery:
Over-the-counter gels or creams: These can numb the area and protect the ulcer from further irritation.
Saltwater rinse: A warm saltwater solution can help reduce inflammation and promote healing.
Avoiding irritating foods: Stay away from spicy, acidic, or rough-textured foods that may aggravate the ulcer.
Proper oral hygiene: Gently brush your teeth and avoid using toothpaste with strong abrasives or sodium lauryl sulfate.

Other Oral Lesions

Cold Sores (Herpes Simplex Virus Lesions)

Cold sores, also known as fever blisters, are caused by the herpes simplex virus (HSV). They often appear on or around the lips and can be contagious. Cold sores usually form clusters of blisters that burst and then scab over. The virus can remain dormant in the body, causing outbreaks during times of stress, illness, or immune system suppression.

Leukoplakia

Leukoplakia refers to white or gray patches that form on the tongue, gums, or inside of the cheeks. These patches cannot be scraped off and may be a result of tobacco use, alcohol consumption, or chronic irritation. In some cases, leukoplakia may indicate precancerous changes, and it’s important to have it evaluated by a healthcare provider.

Lichen Planus

Lichen planus is an inflammatory condition that causes white, lacy patches or sores in the mouth. These lesions can be painful and may appear on the cheeks, gums, or tongue. The exact cause is unknown, but it is thought to be related to an immune system response. Lichen planus can sometimes cause long-term irritation and discomfort.

Candidiasis (Oral Thrush)

Oral thrush is a fungal infection caused by the overgrowth of Candida yeast in the mouth. It typically presents as white patches on the tongue, inner cheeks, or roof of the mouth. Thrush is more common in individuals with weakened immune systems, such as those with diabetes, HIV, or cancer treatments.

Aphthous Stomatitis

Aphthous stomatitis refers to a group of painful, non-contagious mouth sores that often recur. These sores may appear in the mouth or on the gums, and while they are typically self-limiting, they can cause significant discomfort. They vary in size and severity and are often linked to stress or immune system imbalances.

Oral Cancer Lesions

Oral cancer lesions are abnormal growths that can appear in the mouth, tongue, or throat. These lesions may be painless or painful, and they could be white, red, or mixed in color. Risk factors include tobacco and alcohol use, a history of oral infections, or prolonged sun exposure. Early detection of oral cancer is key to successful treatment, so it's important to consult a doctor or dentist if you notice any persistent, unusual lesions.

Causes of Oral Lesions

There are numerous causes of oral lesions, including:
Infections: Viral, bacterial, or fungal infections can lead to oral lesions.
Trauma: Injury from dental procedures, biting the inside of your cheek, or irritation from dentures.
Underlying conditions: Conditions such as autoimmune diseases, cancer, or nutritional deficiencies may cause lesions.
Environmental factors: Tobacco use, alcohol consumption, or poor oral hygiene can irritate the mouth and contribute to the development of lesions.

How to Treat Oral Lesions

Treatment for oral lesions depends on their cause and severity. Some options include:
Topical treatments: Over-the-counter creams, gels, or ointments can help relieve pain and inflammation.
Oral medications: If the lesion is caused by infection or an underlying condition, antibiotics, antivirals, or antifungals may be prescribed.
Good oral hygiene: Keeping the mouth clean can help prevent further irritation and infection.
Avoiding triggers: In some cases, avoiding certain foods, alcohol, or smoking can prevent the development of oral lesions.

When to see a Doctor?

If you notice any of the following symptoms, it’s important to seek medical advice:
A lesion that lasts longer than two weeks
Severe pain or swelling
Difficulty eating or drinking
Unexplained weight loss or bleeding from the lesion
