Description of Mouth ulcers

Mouth ulcers are small sores in the mouth that may be present on the insides of the cheeks, on the tongue, or the roof of the mouth.
Causes and Risk Factors
There are many causes of mouth ulcers:
1. Mechanical trauma such as rough brushing, use of braces, biting the insides of the mouth, or eating foods that may scratch the insides.
2. Eating very hot foods
3. Sensitivity to foods such as peanuts
4. Nutritional deficiencies such as that of iron, folic acid or vitamin B12
5. Infection such as candida or herpes
6. Gastrointestinal problems such as Crohn’s disease
7. Reactions to certain medicines such as aspirin, ibuprofen, beta-blockers, and blood pressure medicines

Signs and Symptoms
The symptoms of mouth ulcers include:
1. A sore inside the mouth
2. Pain
3. Difficulty eating food
4. Fever
5. Swollen lymph nodes
The doctor will physically examine the ulcers in the mouth. Treating the underlying condition or the cause of the sores will usually prevent them from coming back.
Treatment of mouth ulcers involve:
1. Antibiotics -- it may be oral or in the form of a rinse
2. Corticosteroids to be applied on the sores
3. Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain

Some home remedies that may help treat mouth ulcers include:
1. Apply honey on the ulcers using a cotton swab. Do it a few times a day.
2. Apply glycerin on the ulcers.
3. Chew some tulsi leaves a couple of times a day.
4. Prepare a decoction of coriander seeds by boiling a teaspoon of seeds in a cup of water. When cold, use it to rinse your mouth.
5. Prepare a mouth rinse using sea salt. Add 2 teaspoons of sea salt in a glass of water and rinse your mouth with it.
6. Drink licorice tea a few times a day.
Complications and When Should You See a Doctor
The complications of mouth ulcers include:
1. Infection that spreads to the teeth
2. Infection of the skin and floor of the mouth
3. Oral cancer

See a doctor if:
