Understanding Mouth Ulcers and Canker Sores: Causes, Symptoms, 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 ailments affect millions of people worldwide and can cause discomfort while eating, drinking, and speaking. Although they are often used interchangeably, the terms ”mouth ulcer” and ”canker sore” generally refer to the same condition.

Causes of mouth ulcers and canker sores can vary, and in many cases, the exact trigger is unknown. However, several factors have been identified as potential contributors:

Minor injuries: Accidentally biting the inside of your cheek or brushing too vigorously can cause small wounds that develop into ulcers.

Nutritional deficiencies: Lack of essential nutrients like vitamin B12, zinc, folate, or iron may increase the likelihood of developing mouth ulcers.

Stress and hormonal changes: Emotional stress or hormonal fluctuations, such as those during menstruation, can trigger outbreaks.

Food sensitivities: Certain foods, particularly acidic or spicy items, may irritate the mouth's soft tissues and lead to ulcers.

Immune system issues: Some autoimmune conditions, like Beh?et's disease or inflammatory bowel disease, can increase the risk of developing mouth ulcers.

Genetic predisposition: Some individuals may be more prone to developing canker sores due to their genetic makeup.

Symptoms of mouth ulcers typically include:

Small, round, or oval sores with a white or yellow center and a red border

Pain or burning sensation, especially when eating or drinking

Difficulty speaking or swallowing, depending on the location of the ulcer

In some cases, fever, swollen lymph nodes, or general malaise

Most mouth ulcers are minor and heal on their own within 1-2 weeks without leaving scars. However, larger or more persistent ulcers may require medical attention. It's important to distinguish canker sores from cold sores, which are caused by the herpes simplex virus and typically appear on the outer lips.

Treatment for mouth ulcers and canker sores often focuses on managing symptoms and promoting healing. Some effective strategies include:

Over-the-counter topical treatments: Gels or ointments containing benzocaine or lidocaine can provide temporary pain relief.

Antimicrobial mouthwashes: Rinsing with chlorhexidine or hydrogen peroxide solutions can help prevent secondary infections and promote healing.

Salt water rinses: Gargling with warm salt water can soothe the affected area and may speed up healing.

Avoiding irritants: Steer clear of spicy, acidic, or rough foods that may further irritate the ulcer.

Applying ice or sucking on ice chips: This can help numb the area and reduce pain.

Using a soft-bristled toothbrush: This helps minimize irritation during oral hygiene routines.

Taking vitamin and mineral supplements: Addressing nutritional deficiencies may help prevent future outbreaks.

For severe or persistent cases, a healthcare provider may prescribe:

Stronger topical corticosteroids to reduce inflammation

Cauterization to chemically burn and seal the ulcer

Systemic medications for underlying conditions that may be causing recurrent ulcers

Prevention strategies for mouth ulcers include maintaining good oral hygiene, eating a balanced diet rich in vitamins and minerals, managing stress levels, and identifying and avoiding personal triggers. If you experience frequent or particularly painful mouth ulcers, it's advisable to consult with a dentist or doctor to rule out any underlying health conditions.
