What are canker sores?

Canker sores, canker sores or more commonly known as canker sores, are wounds that appear on the mucosa of the mouth, and therefore can occur anywhere in the mouth, whether on the tongue, mussels, gums or lips . These are characterized by having a whitish color, are annoying and a little painful. The sores usually last about seven days.

What is the reason for its appearance?

We have to take into account that, as with herpes, the genetic predisposition influences. Apart from this, there can be several reasons why we get an ulcer.

Among the most common reasons are:

  • Lack of iron or vitamins
  • Lack of hygiene
  • Some type of allergy is usually caused by some food to which we are allergic.
  • Bacterial or viral infections: these lower the defenses and therefore favor their appearance.
  • Because they are exposed to a lot of pressure, stress or anxiety, they are also reasons that influence the appearance.

Another reason that is very frequent but more specific to specific patients, are those who are under orthodontic treatment with braces, or those who wear a dental prosthesis. It is normal in both cases, since we must be aware that they wear protruding devices and therefore rub with some part of the mouth. For these cases, there is an easy solution and it is dental wax.

How to prevent them?

As we have said, a genetic factor also comes into play but we give some tips that will help prevent its occurrence:

A balanced diet is very important, in which foods that have many minerals and vitamins abound
A good oral hygiene routine is always essential
Moisturize the lips continuously, which will help not appear so many wounds in the mouth.

In the event that the sores persist longer, than a week, and some symptoms are experienced such as swallowing difficulties or fever, it is advisable to visit the dentist to be able to apply an appropriate treatment.
