Oral Ulcer (Part I): Foreign Name [Aphtha]

If one day you see a friend with a frown, silence, a face of displeasure, not thinking about tea and food, and even giving up his favorite snacks, you may also ask him if he has oral ulcer before suspecting that he is lovelorn and depressed.

Our daily oral ulcer often refers to [recurrent oral ulcer], also known as [recurrent aphthous ulcer] and other similar names, is the most common oral mucosal disease. It is reported that 20% of the people have experienced oral ulcer, regardless of age, sex, race, can occur.

First, is what a recurrent aphthous ulcer?

1. As the name implies

The word “aphtha” comes from Greek and means “burning pain”. It can be seen that the most direct impression of ulcer is pain-it hurts to speak, eat, and swallow saliva when nothing happens. It directly teaches people to feel low and unhappy.

[Recurrence] is another important feature of this kind of disease, and the recurrence interval varies from several months to one after another. Seeing this ulcer gradually improve, another one begins to sprout again.

However, there is always exciting information. What we often say about oral ulcer, that is, recurrent aphthous ulcer, is self-limiting. In other words, if we don’t take medicine or see a doctor, it will heal automatically! Of course, it is limited to those who can really endure the pain and are extremely sure that they are not suffering from other diseases or oral manifestations of other diseases-and this still needs doctors to judge.

2. Typical Performance

Oral ulcer is generally manifested as recurrent round ulcer, which is characterized by four words: [yellow], [red], [concave] and [pain].


Refers to the ulcer surface has yellow (sometimes a little gray) pseudomembrane;


Refers to an ulcer with a red congestion zone on the edge;


It means that the ulcer itself is sunken.


Obvious burning pain often affects eating, speech and even the mental state of the whole person.

Second, the cause is unknown!

Yes! The cause is unknown!

Like the common cold, it seems that the more common the disease, the more elusive it is.

Some scholars have put forward the theory of heredity, environment and immunity [triple factors] for the onset of oral ulcer. This theory holds that oral ulcer will occur if the body has abnormal immune response under the genetic background of susceptibility and appropriate environmental factors.

We often find that in our life, Among a group of classmates, colleagues and friends with very similar lifestyles, some people suffer from ulcers repeatedly, while others never know the taste of ulcers. Researchers have found that oral ulcers are obviously familial. The [genetic background] mentioned above, that is, the genetic information given to us by parents, including chromosomes, cannot be changed.

Environmental factors include mental and psychological factors, working environment and social environment, which are relatively easy to control. I wonder if you find that people around you are more prone to oral ulcer when exams come, looking for a new job or encountering setbacks in life, which is probably the reason.

Third, the symptoms are changeable.

It is also oral ulcer. Some people have very mild symptoms, while others die and live. Some people grow only a few times a year, while others grow from one to the other. Some people grow one at a time, while others have four or five at a time. These are all oral ulcers, which specifically involve the classification of diseases. Now they are mainly divided into mild, severe and herpetic ulcers.

1. Mild oral ulcer

Mild oral ulcer is the most common, accounting for 80% of all patients with oral ulcer. It mainly occurs in oral mucosa of lip, tongue, cheek, palate and other parts, and its size will not exceed 5 mm.

The course of its disease is relatively short, usually it starts to heal after 5 days, and it can heal after 7 ~ 10 days without leaving scars. During the whole process, you will not feel too painful.

The remaining two are relatively rare and serious.

2. Severe oral ulcer

The diameter of severe oral ulcer will be larger than 1 cm, which is deeper and more painful than mild ulcer, and the duration may be as long as 1-2 months.

3. Herpetic ulcer

When herpes ulcers occur, as many as a dozen to dozens of small and dense ulcers with a diameter of 2 mm grow in the mouth like [baby’s breath]. This kind of ulcer is quite ferocious.

Because it is rare, the risk of severe and herpes ulcers also increases. When you find deep ulcers in your mouth that cannot heal for a long time, you need to be on guard: some oral cancers are also common. At this time, the first thing you should do is not to smear (sprinkle) drugs (salt) on them, but to go to the dentist for help.
