Mouth sores come in different forms and result from different causes. Some mouth sores may be bigger and hurt more while others are smaller and cause only minor discomfort. If you get mouth sores frequently, understanding their causes will make getting the proper treatment easier. Here are four common causes of mouth sores and what you can do about them.


Stress is a known culprit of mouth sores. The immune system is often weakened with stress, which can make fighting off infections inside the mouth more difficult and lead to mouth sores. If you experience frequent stress in your daily life, you can try activities like yoga and meditation to try to calm your nerves and prevent mouth sores from developing. Medications can also be prescribed to alleviate stress if you’re having difficulty feeling calmer.

Cheek and Lip Biting

Biting your lip or the inside of your cheeks can leave wounds that eventually turn into mouth sores. Canker sores often result from these types of mouth injuries and can make eating and speaking difficult. If you’re in the habit of gnawing on your lip or the inside of your cheeks, it’s advisable that you make conscious efforts to stop the habit so that your mouth stays healthier. A mouth guard may also be required if you frequently bite the inside tissues of your mouth while sleeping. If any mouth wounds from biting are severe enough, you might need to visit an emergency dentist for care.

Symptom of a Medical Condition

Certain medical conditions are known to cause symptoms such as mouth sores. Celiac disease, which affects the body’s ability to process gluten, often leads to the development of mouth sores. You may also get sores inside your mouth regularly if you have Crohn’s disease. Getting treatment to lessen the effects of these conditions can help alleviate mouth sores.

Herpes Viral Infection

Sores from the herpes simplex virus can occur inside the mouth as well as on outside areas of the lips. During an outbreak, you should refrain from kissing or other sexual activities that could infect another person with the virus. Even though you can’t be cured from the herpes virus, there are antiviral medications that can help reduce mouth sores and other related symptoms.

If you’re bothered by mouth sores, there are certain proactive measures that you can take to keep these infections from interfering too much with your life. Getting the right treatment as soon as possible can save you a lot of extra pain and distress.
