What Is the Origin, How to Prevent and How to Treat

Origin Treatment

If you have or have ever had a painful white wound inside your mouth, then you are perfectly familiar with canker sores! There are numerous types of sores on the mouth, lips, and tongue, from irritations, lesions, and bumps. The most common pathologies are thrush, herpes, leukoplakia, and candidiasis. About 1/3 of the population has or has had mouth lesions at some point in their life. Wounds, irritations, and lesions of the mouth can be painful and can interfere with chewing and speech. Any wound that has been in the mouth for more than two weeks should be examined by your dentist. Ultimately a biopsy may be needed to determine the cause!

Today we speak of canker sores that are small wounds or lesions that arise in the mouth, namely in the oral mucosa, gingiva, tongue or lips. They can appear alone or grouped, are flattened, round or oval and can have several colors (white, red or yellowish). They cause pain, discomfort, and difficulties in eating, drinking and even talking. Small whitish oral ulcers are benign and harmless lesions despite causing pain. They reveal that our immune system is down and can be caused by different factors, including food and stress.


It is not always possible to know what gave rise to one or more canker sores, although we may be wary of some of the causes:

– Stress;
– Intraoral trauma (accidental bites on the tongue or the inside of the cheek);
– Hormonal changes during the menstrual cycle;
– Diet;
– Genetic, immunological or microbiological factors;
– Changes in oral ph.


Treatment is mainly symptomatic because canker sores heal spontaneously within one to two weeks, even without treatment. Some products or drugs may be used to help alleviate symptoms and prevent possible infections. Thus, treatment may include:

– Antiseptic and antibacterial solutions (mouthwashes, gels or drops);
– Analgesics and anti-inflammatories of local application;
– The protective gel of the oral mucosa.


It is believed that there is a link between canker sores and vitamin deficiency, so eating well and taking a multivitamin are good choices if you are predisposed to have canker sores in your mouth. Probiotics are also considered useful.

To conclude, I emphasize that canker sores are not contagious because they do not originate agents such as viruses, bacteria or fungi.

Thrills should not be confused with herpes. This one is contagious. In the case of herpes, the lesions appear mainly on the lips or around the mouth and give different symptoms, such as stinging or burning sensation.
