  Canker sores (recurrent aphthous stomatitis, RAS) are among the most common of oral conditions and are experienced by more than half of the population. […] The cause of canker sores is not known. However, in some instances, they can be a sign of other conditions affecting the body (such as a gastrointestinal disease). […] A: No one really knows, but it is thought to be caused by an immune system malfunction that causes white blood cells to temporarily attack the mucosal cells lining the mouth. Sometimes they are a form of allergic reaction to food ingredients or components of toothpastes or mouthwash. Canker sores can also be associated with some systemic conditions such a Crohns disease and nutritional deficiencies.

[…] The causes of recurrent cases of canker sore known as recurrent oral aphthous ulcers or recurrent aphthous stomatitis are also unclear, although there are links with a number of factors including a family history of aphthous ulcers, and allergies. […] The following factors are thought to be involved in the development of canker sores: Hormonal changes. Physical trauma (damage to the lining of the mouth, such as during dental treatment). Drugs. Food hypersensitivity for instance, citrus fruits and tomatoes can trigger or worsen a canker sore. Nutritional deficiencies, including iron, folic acid, zinc, and vitamin B12. Stress.

  Canker sores usually begin showing up between the ages of 10 and 20, although they can happen at any time in a person’s life. […] No one knows exactly what causes them. But they can run in families. That means if your parents or siblings get canker sores, the genes you share with them make it more likely that you’ll develop the sores too. […] There may be a connection between canker sores and stress. If you get canker sores around exam time or some other big event in your life, it may be a sign of how much stress you’re under. […] Mouth injuries (like biting the inside of the lip or even brushing too hard and damaging the delicate lining inside the mouth) also seem to bring on canker sores. Sodium lauryl sulfate (SLS), an ingredient in many toothpastes and mouthwashes, has been linked to canker sores, and sometimes the sores can be a sign of an immune system problem. […] Finally, not getting the right nutrition (such as not getting enough iron or vitamin B12) also might contribute to some cases of canker sores.

  The cause is not completely understood but involves a T cell-mediated immune response triggered by a variety of factors which may include nutritional deficiencies, local trauma, stress, hormonal influences, allergies, genetic predisposition, certain foods, dehydration, some food additives, or some hygienic chemical additives like SDS (common in toothpaste). […] The cause is not entirely clear, but is thought to be multifactorial. It has been suggested that aphthous stomatitis is not a single entity, but rather a group of conditions with different causes. […] Evidence for the T cell-mediated mechanism of mucosal destruction is strong, but the exact triggers for this process are unknown and are thought to be multiple and varied from one person to the next. This suggests that there are a number of possible triggers, each of which is capable of producing the disease in different subgroups.

• #7 Aphthous stomatitis – Wikipedia

  https://en.wikipedia.org/wiki/Aphthous_stomatitis

  Risk factors in aphthous stomatitis are also sometimes considered as either host-related or environmental. […] Aphthous stomatitis has been associated with other autoimmune diseases, namely systemic lupus erythematosus, Behet’s disease and inflammatory bowel diseases. However, common autoantibodies are not detected in most patients, and the condition tends to resolve spontaneously with advancing age rather than worsen. […] The nutritional deficiencies associated with aphthous stomatitis (vitamin B12, folate, and iron) can all cause a decrease in the thickness of the oral mucosa (atrophy). […] Local trauma is also associated with aphthous stomatitis, and it is known that trauma can decrease the mucosal barrier. Trauma could occur during injections of local anesthetic in the mouth, or otherwise during dental treatments, frictional trauma from a sharp surface in the mouth such as broken tooth, or from tooth brushing.

[…] Although no unifying theory of the immunopathogenesis of recurrent aphthous ulcer has been established, immune dysregulation appears to play a significant role. […] Researchers have disagreed about the role of microbes in the development of recurrent aphthous ulcers. The emphasis has been on a microbial agent as a primary pathogen or an antigenic stimulus. Numerous studies have failed to provide strong evidence to support the role of HSV, human herpesvirus (HHV), varicella-zoster virus (VZV), or cytomegalovirus (CMV) in the development of aphthous ulcers. […] Recurrent aphthous ulcer formation may be a T-cell-mediated response to antigens of Streptococcus sanguis that cross-react with the mitochondrial heat-shock proteins and induce damage to oral mucosa.
