Mostly they form on any soft tissues of the mouth including the inside cheeks, lips, gums, tongue, the roof and floor of the mouth. Mouth sores can as well develop on your esophagus (the tube that runs from the neck to your stomach). Sores that form in the mouth are also referred to as canker sores or mouth ulcers or aphthous stomatitis.

Sore inside Mouth Causes

The exact cause of sores in the mouth is not known. However, there are numerous issues that are linked to the formation of this ulceration in the mouth. Some researchers have linked them to excess stress, the food we eat and some drinks we take as well. Some cases of complex canker sores are linked to underlying health conditions in our body such as poor immune system, nutritional problems or some gastrointestinal tract diseases.

We are going to share some of the common reasons why you may develop a sore inside mouth although there are very many things that may cause this ulceration. The causes of sores in the mouth may include the following:

Causes of sore inside mouth

  1. Tissue injury

Tissue injury in the mouth may be due to aggressive brushing of teeth, accidentally biting your tongue, cheek or lip, experiencing irritation from sharp objects such as braces, retainer, or dentures. All these may cause a fracture on the thin skin that is found inside your mouth. We all know that yeast is naturally found in our mouth and therefore in case there are conditions that facilitate it to cause infection, then it will. When the inner mouth is cut due to all these reasons we have listed, this exposes the wound to numerous infections that could cause a sore inside mouth to develop from the wound.

  1. Underlying heath conditions

Some health conditions such as HIV or cancer can cause your immune system to become weak. When the immune system is weak this means that your body mechanism of preventing you from small infections such as HPV 1 can become problematic. In this case, you will be easily attacked by sores in the mouth. Moreover, nutritional problems such as lack of important nutrients like vitamin B – 12, zinc, folic acid, or iron deficiency can make your body weak when it comes to healing of small cuts in the mouth and therefore these cuts end up developing into sores.

  1. Irritation from certain foods

Some food s has a lot of acid and therefore they may easily cause irritation on the thin membrane skin that is found in the mouth. Some of the foods that much in acid are citrus fruits such as lemon, orange, pineapple, apple, fig, tomato and strawberry. Also, most of the vegetables we eat usually contain a lot of acid. All these foods may cause cuts in the mouth or in some cases they may result in allergy of the skin to other people. This is the reason why while you eat these foods you feel like something is cutting in the mouth.

However, if vegetables are well cooked, the acidic level usually goes down and they may rarely cause this problem in the mouth. Also, blending the fruit so that you drink eat in juice form may lessen the effect of the acid since it is directly swallowed before it causes problems in the mouth.

  1. Stress

Stress is also considered to be the cause of sore inside mouth although sources do not explain how. Some of the researchers have linked stress to cause changes in the levels of hormones. Stress usually increases hormonal activities and in turn these may cause the formation of canker sores. Yes, it has been proven that people who have excess stress usually have sores in their mouths in many occasions. In that case, we are being advised to always avoid stress so as to avoid formation of sores inside mouth.

  1. Impaired immune system

If you have a weak immune system, this means that your body mechanism to respond to any infection will be poor. We all know that infections causing organisms such as bacteria, virus and fungus usually take advantage of open wound on our skin and if the body mechanism to fight attack is poor, the infection will be successful. It is very easy for people with poor immune system to develop a sore inside mouth as compared to people who have strong immunity. This is because, whenever they develop a cut in the mouth, their body is strong enough to fight any infection that may have wanted to take advantage of the open wound.

  1. Gastrointestinal tract diseases

These may include diseases such as celiac disease and Cohn’s disease. The digestive system starts from the mouth going down through the stomach in the large intestine. Therefore, the likely wood that an infection taking place inside your intestine may pose a certain effect in your mouth is high. Some of these diseases that take place in the intestinal tract usually cause the development of sores in the mouth as some of their symptoms.

  1. Chewing tobacco

Generally, nicotine found in tobacco can cause tooth abrasion, gum recession and increased tooth decay. Constant irritation to the area in your mouth where a small amount of chewing tobacco is placed may result in the gums pulling away from the teeth, exposing the inner part of the gum and the root surface of the teeth. This may be seen as ulceration on the gums. This may expose the open wound to possible infections and even your teeth are likely to start rotting since their roots are exposed. This is the reason why people chewing tobacco are likely to end up with sores inside mouth mostly forming on their gums.

  1. Herpes simplex virus type 1

Yeast is naturally found on our body including in the mouth in a harmless state. If your immune system is compromised, the naturally occurring yeast is allowed to overgrow and therefore causing an infection. In this case, any minor cut or wound in the mouth may end up developing into a sore inside mouth since the body mechanism of fighting minor infections is compromised.

  1. Reaction to medication

Some medication that we acquire over the counter may cause formation of mouth sores as part of their side effects. Moreover, medications such as radiation or chemotherapy are mostly associated with sores in the mouth as well. In this case, talk to your doctor in case the medication you are using is causing you severe side effects so that he/she may find out an option for you.

  1. Cancer

Sore inside mouth can be categorized among many symptoms that are associated with cancer. However, it does not mean that if you have canker sores you have cancer since it is a rare condition with much severe symptoms.
