If Your Mouth Ulcer Hurts
A mouth ulcer is a painful sore that forms inside the mouth.
It can cause discomfort while eating or speaking. Mouth ulcers range from mild to severe, and their causes can vary widely.

Mouth Ulcer
Possible causes of mouth ulcers include the following.
- Aphthous stomatitis : This is the most common type of mouth ulcer, characterized by painful, whitish sores inside the mouth. It is often triggered by weakened immunity, stress, or nutritional imbalances.
- Herpes virus infection : Mouth ulcers can be caused by oral or lip herpes. These ulcers are typically accompanied by pain and itching.
- Oral candidiasis : When the immune system is weakened, Candida fungi can overgrow in the mouth and cause ulcers.
- Irritation from brushing or food : Spicy or acidic foods can directly worsen mouth ulcers. Accidental injury to the oral mucosa during brushing or eating can also lead to ulcer formation.
- Medication side effects : Certain medications may cause mouth ulcers as a side effect.

Oral Hygiene Management and Regular Dental Checkups
Brush your teeth carefully and keep your mouth clean. Avoid using strongly abrasive toothpaste or hard-bristled toothbrushes.
If you frequently develop mouth ulcers or they take a long time to heal, it’s important to consult a dentist. There may be an underlying condition. While most mouth ulcers cause only temporary discomfort, recurring or slow-healing ulcers should be checked by a doctor.
Maintain good oral hygiene daily and adopt a lifestyle that helps strengthen your immune system.
