Mouth Ulcers and Canker Sores: Causes and Remedies

Mouth Ulcers and Canker Sores: Causes and Remedies

Mouth ulcers and canker sores are common oral problems that reduce quality of life, making it difficult to eat and speak. Small sores inside the mouth, known as canker sores, appear in most people at least a few times. So, what is a canker sore, what causes it, and how can it be treated? Let’s take a closer look at all the details about mouth ulcers.

What is a Canker Sore?
A canker sore is a small ulcer that appears on the mucosal surface inside the mouth, usually white or yellow in color, with a red inflamed border. They commonly occur on the tongue, inner cheeks, inner lips, gums, and soft palate. Their size can range from a few millimeters to up to a centimeter.

Although not contagious, canker sores negatively affect daily life due to their painful nature. Some people may experience them a few times a year, while for others, they may become chronic and recurrent.

Causes of Mouth Ulcers and Canker Sores
The exact cause of canker sores is not fully known, but several factors are thought to play a triggering role. Here are the most common causes:

1. Stress and Fatigue
High stress and irregular sleep weaken the immune system and make it easier for canker sores to develop.

2. Weakened Immune System
A weakened defense mechanism makes it harder for mouth ulcers to heal and leads to the formation of new sores.

3. Nutritional Deficiencies
Deficiencies in vitamin B12, folic acid, iron, and zinc play an important role in the formation of canker sores. These vitamins and minerals are critical for oral health.

4. Oral Trauma
Aggressive brushing, accidentally biting the cheek or tongue, or friction from dentures or braces can cause mouth ulcers.

5. Hormonal Changes
In women, menstruation, pregnancy, or hormonal fluctuations can trigger canker sores.

6. Food Consumption
Overly spicy, acidic, or very hot foods can irritate the oral mucosa and cause canker sores. Chocolate, citrus fruits, and certain nuts can also be triggers.

7. Genetic Predisposition
People who suffer from canker sores often have relatives with the same condition, indicating a genetic influence.

Symptoms of Mouth Ulcers and Canker Sores

The most distinctive feature of a canker sore is the small lesion inside the mouth that causes pain. Other symptoms include:

- Burning or stinging sensation
- Increased pain when eating, especially acidic or spicy foods
- Difficulty speaking
- Recurring sores
- White or yellow patches surrounded by redness

How to Treat Mouth Ulcers and Canker Sores

Canker sores usually heal on their own within 7–10 days. However, various methods can be used to reduce pain and discomfort during this period.

1. Gargling with Salt Water
Salt water disinfects the mouth and speeds up healing. Gargling several times a day can be beneficial.

2. Gargling with Baking Soda Solution
Baking soda neutralizes the acidic environment in the mouth and helps canker sores heal.

3. Use of Medications and Gels
Gels and sprays available in pharmacies can reduce pain and support healing.

4. Vitamin Supplements
If there is a deficiency in vitamin B12, folic acid, or iron, supplements should be taken under medical supervision.

5. Avoiding Stress
Managing stress is an important step in preventing the recurrence of canker sores. Regular sleep and a healthy lifestyle reduce the risk.

6. Balanced Diet
Consuming vegetables and fruits rich in vitamin C strengthens the immune system and helps sores heal faster.

Prevention Methods for Canker Sores

Some measures can help prevent the recurrence of mouth ulcers:

- Regular and gentle tooth brushing
- Avoiding hard foods
- Limiting smoking and alcohol consumption
- Eating a diet rich in vitamins and minerals
- Engaging in stress-reducing activities (exercise, meditation, etc.)

These simple habits significantly reduce the risk of developing canker sores.

When to See a Doctor

Canker sores are usually simple and temporary problems. However, in some cases, medical consultation is necessary:

- If sores last longer than 2 weeks
- If they occur frequently
- If the sores are very large and painful
- If accompanied by other symptoms such as fever or swollen lymph nodes

In such cases, consulting a dentist or dermatologist is important.

Mouth ulcers and canker sores are usually self-healing but can seriously affect quality of life. Stress, nutritional deficiencies, and oral trauma are among the most common causes. With proper oral care, a balanced diet, and a stress-free lifestyle, the occurrence of canker sores can be greatly reduced.

Remember, protecting your oral health is important not only for aesthetics but also for your overall health. If you experience recurrent or persistent canker sores, be sure to consult a specialist.
