Actually, there is not a huge amount of information about the causes of although many medical professionals believe that a problem with our body’s immune system may be the reason for to develop. The likely triggers that may lead to this problem are many. These include toothpastes and mouthwashes that include a substance called sodium lauryl sulfate.

Products that contain this chemical, in daily use, can cause our mouth to become dry. This drying effect in turn compromises the mouth tissues leaving them vulnerable to various irritants. These irritants may well trigger the body’s lymphocytes to attack the sodium lauryl sulfate that remains in the mouth after tooth brushing, mouth wash or gargle and presto, a mouth ulcer develops.

Discontinuing the use of products containing this chemical has been found to help stop from recurring. Other causes of can be attributed to mechanical trauma and emotional stress. In the instance of mechanical trauma, a physical trauma like an accidentally self inflicted bite is one of the most likely causes, or possibly irritation of some sort that was caused by a sharp tooth edge or maybe even certain food types that can cause irritation or tissue damage, causing to form.

There are also certain infectious agents, both bacterial and viral in nature that are considered as causes of mouth ulcers. The various chemical compounds that are found within the infectious agents are though to be one of the reasons for forming.

Certain medical conditions have also been associated with the formation of mouth ulcers. These include Behcet's disease, neutrophil dysfunction diseases, inflammatory bowel diseases, such as coeliac and Crohn's, and also HIV-AIDS disease. Individuals who have prolonged and continuous difficulty with may benefit from a medical test to ensure that there is no underlying physical cause for their suffering. The results of the test will be able to show this and their doctor will be better able to help treat the whole system if indeed the cause of their is related to an underlying medical condition.

The use of certain types of medication has also been identified as one of the possible causes of mouth ulcers. For example, various non-steroidal anti-inflammatory drugs or NSAIDs, beta blockers, chemotherapeutic agents, and nicorandil have each been found to be possible causes for an outbreak of mouth ulcers.

As we have seen, there are actually many possible reasons for the manifestation of mouth ulcers. However until we have positive medical proof of the particular cause we can only work on the evidence that various triggers have shown and most often treat them with topical applications specially designed to ease the pain and help the tissue to heal.
