Mouth Ulcer
Mild
A mouth ulcer is a small, painful sore that develops on the lining of the mouth, including the inside of the lips or cheeks, tongue, gums, or other soft tissues. Many mouth ulcers are minor and heal on their own within one to two weeks. They can be triggered by accidental injury, irritation, stress, illness, or nutritional deficiencies. Persistent or unusual ulcers require dental or medical assessment.

When to Seek Medical Attention
Most mouth ulcers heal without urgent treatment. Seek dental or medical assessment for an ulcer that persists beyond the expected healing period, repeatedly returns, becomes unusually large or painful, bleeds without an obvious cause, or is accompanied by unexplained weight loss or other concerning symptoms.

Overview
A mouth ulcer is a small, painful sore that develops on the lining of the mouth, including the inside of the lips or cheeks, tongue, gums, or other soft tissues. Many mouth ulcers are minor and heal on their own within one to two weeks. They can be triggered by accidental injury, irritation, stress, illness, or nutritional deficiencies. Persistent or unusual ulcers require dental or medical assessment.
Symptoms 1
Premature Ejaculation
Causes
Mouth ulcers can result from minor trauma such as biting the cheek, sharp teeth, braces, dentures, or burns from hot food. Other possible triggers include stress, hormonal changes, infections, certain medicines, and nutritional deficiencies. Some people develop recurrent ulcers without an identifiable cause. Persistent or multiple ulcers may sometimes occur with underlying inflammatory or systemic disorders.
Risk Factors
Risk factors include previous mouth ulcers, accidental biting or other oral injury, dental appliances, sharp teeth, emotional stress, hormonal changes, and nutritional deficiencies. Certain medicines and foods may trigger ulcers in susceptible people. Poorly fitting dentures and other sources of repeated irritation can also increase the chance of developing sores.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Most mouth ulcers are diagnosed by examining the sore and reviewing the person’s history. A clinician or dentist may assess its size, location, appearance, duration, and recurrence. Testing is generally unnecessary for a typical short-lived ulcer. Blood tests or other investigations may be considered when ulcers are frequent, severe, persistent, associated with other symptoms, or suggest an underlying nutritional or systemic condition.
Prevention
Key Prevention Tips
Some mouth ulcers cannot be completely prevented, but avoiding known triggers may reduce recurrences
Protect the mouth from injury, maintain good oral hygiene, and use care when eating very hot or hard foods
Dental problems and poorly fitting appliances should be corrected
A balanced diet helps prevent nutritional deficiencies
Seek evaluation for ulcers that do not heal within a reasonable period or repeatedly return
