Canker and mouth sores are small wounds that manifest in the mouth. Although they tend to be small, their location makes them uncomfortable and painful. Hot, cold, crunchy, and acidic foods can irritate them, causing further discomfort.

They take a while to cure due to the moisture in the mouth and the consumption of food. So, we wanted to find a quick solution that treats and relieves painful sores and mouth sores. In today’s article, we’ll you the solutions we found to help cure canker and mouth sores fast.

The causes of canker and mouth sores

Although they’re very common, the truth is that no one knows precisely why they appear. What we do know is that canker and mouth sores cause painful speaking and eating. There are two types: simple or complex.

The first type appear a few times a year and last for about a week. The second type are less common and people afflicted by them usually had some sort of mouth sore before. The appearance of sores could be the result of many things. Some factors that might trigger them are:

  • According to this study of the Faculty of Dentistry of the Complutense University of Madrid, stress might be linked to mouth sores.
  • Acid or citrus intake.
  • Injuries from food or eating utensils.
  • Nutritional problems or gastrointestinal disease (although there’s no evidence to support this).
  • Orthodontic devices.

We must pay attention to the difference between canker sores and herpes labialis, which can be identical in their appearance. Herpes labialis is caused by a simple virus and is contagious, while canker sores aren’t. In addition, the former may appear on other parts of the face, such as the lips, nose, and under the chin.

If you have a canker sore, you may experience burning and a painful tingling sensation, as well as white or gray round sores with red borders. Also, you may have a fever and swollen lymph nodes.

The good thing about canker sores is that they almost always disappear on their own. The pain can be very bothersome, but the important thing isn’t to touch it with your teeth nor tongue, even though you may be tempted to. They’ll be a bad memory in a period of seven to ten days.
