Mouth sores can be painful and sometimes embarrassing, making it difficult to eat or speak. They are a common occurrence and typically go away on their own within a few days to weeks.

However, it is important to understand the causes and treatments of mouth sores to prevent them from recurring or becoming more severe.

Causes of Mouth Sores

Mouth sores can be caused by a variety of factors, ranging from allergies to viral infections. Some common causes of mouth sores include:.

1. Canker Sores

Canker sores, also known as aphthous ulcers, are a type of mouth sore that appears as a white or yellowish oval-shaped lesion with a red border. They are typically small, about the size of a pea, and can be painful when eating or speaking.

The exact cause of canker sores is unknown, but they are believed to be linked to stress, genetics, or an immune system response.

2. Cold Sores

Cold sores, also known as fever blisters, are caused by the herpes simplex virus and typically appear on or around the lips, although they can also appear in the mouth. They start as a small blister and then burst, leaving a painful red sore.

Cold sores are highly contagious and can be spread through contact with the sore, such as kissing or sharing utensils.

3. Oral Thrush

Oral thrush is a fungal infection caused by Candida yeast. It appears as white or cream-colored lesions on the tongue, inner cheeks, and roof of the mouth. Oral thrush is more common in infants, the elderly, and people with weakened immune systems.

4. Allergic Reactions

Mouth sores can also be caused by allergic reactions to food, medication, or oral care products. Symptoms can include red or swollen gums, a burning sensation, and sores or blisters in the mouth.

5. Trauma

Mouth sores can sometimes be caused by trauma, such as accidentally biting the inside of your cheek or brushing too hard. They may also occur after dental procedures, such as getting braces or dentures.

Treatment Options for Mouth Sores

The treatment for mouth sores depends on the cause and severity of the sore. Some common treatment options include:.

1. Over-the-Counter Medications

Over-the-counter medications such as pain relievers, topical creams, and ointments can help alleviate pain and discomfort associated with mouth sores. Some products may also help speed up the healing process.

2. Prescription Medications

If mouth sores are caused by a bacterial infection, antiviral medication, or antibiotics may be prescribed. Prescription-strength mouthwashes and gels may also help alleviate pain and promote healing.

3. Home Remedies

Some home remedies can help alleviate the pain and discomfort associated with mouth sores. Rinsing your mouth with salt water or using a baking soda and water mixture can help soothe the sore.

Eating soft, bland foods and avoiding acidic or spicy foods can also help promote healing.

4. Prevention

Preventing mouth sores can be done by practicing good oral hygiene, avoiding triggers such as stress and certain foods, and quitting smoking.

Additionally, wearing a mouthguard during sports activities or when grinding your teeth at night can help prevent trauma to the mouth.

When to See a Doctor

If mouth sores are severe, persist for more than two weeks, or are accompanied by a fever, it is important to see a doctor. Mouth sores may be a sign of an underlying medical condition, such as a vitamin deficiency or autoimmune disorder.
