Understanding Mouth Ulcers: Causes, Symptoms & Relief

Mouth ulcers, also known as canker sores, are common, painful sores that can develop on the inside of the mouth. They can be caused by a variety of factors, including:

* Trauma: Biting the inside of your mouth, brushing your teeth too vigorously, or wearing dentures that don't fit properly can all cause mouth ulcers.

* Illness: Canker sores are also often associated with certain illnesses, such as the common cold, influenza, and Crohn's disease.

* Nutritional deficiencies: A lack of certain vitamins and minerals, such as vitamin B12, iron, and folate, can lead to mouth ulcers.

* Hormonal changes: Women are more likely to develop mouth ulcers during menstruation or pregnancy.

* Stress: Stress can trigger mouth ulcers in some people.

* Food allergies: Some people develop mouth ulcers after eating certain foods, such as nuts, chocolate, and coffee.

* Medical conditions: Certain medical conditions, such as celiac disease, Behçet's disease, and HIV/AIDS, can also cause mouth ulcers.

In most cases, mouth ulcers are harmless and will resolve on their own within a few weeks. However, they can be painful and make it difficult to eat and drink. If you have frequent mouth ulcers, talk to your doctor.
