Mouth Sores: Types, Causes, Treatments and Remedies

The most prevalent illness affecting the mucous membranes lining the mouth is mouth sores. According to researchers, it affects 1 in 10 persons, but this disease’s exact return frequency is unknown.

On the other hand, mouth sores might be minor, self-treated, or significant and require medical attention and treatment. Did you know that only 15% of individuals have severe mouth sores that need to be treated medically, whereas the rest only have minor mouth sores?

1. Mouth Sore v/s Mouth Ulcer

A mouth sore is a painful wound or injury that forms in your oral muscle tissues and may appear on your lips, gums, cheeks, tongue, or the inside or roof of your mouth. Whereas mouth ulcer is a ‘broad term’ that explains any sore or ulceration inside your mouth.

The only difference between them is their underlying cause. Mouth sores are caused by aphthous stomatitis, commonly known as ‘canker sores.’ On the other hand, mouth ulcers are usually caused by a viral infection of the mouth.

2. Types of Mouth Sores

Mouth sores that damage the oral cavity come in several forms. The following describes these mouth sores:

3. Symptoms of Mouth Sores

Depending on the type of mouth sore you have, your symptoms may differ. Most often, lesions cause discomfort, inflammation, redness, and swollen mouth.

Symptoms of mouth sores can be like:-

  • Burning sensation in the mouth- Mouth sores can lead to a burning or tingling sensation in the mouth, which might come and go on its own. As stated, these can mainly cause yeast or bacteria infection, called thrush.
  • Bleeding and swelling in gums- This symptom is mainly a cause of gingivitiswhere the gums become red and swollen. The gums bleed when you clean your teeth but cause no pain until it reaches a serious stage.
  • Dysphagia A feeling of difficulty swallowing food or drinking water arising from the esophagus due to the large spread of mouth sores in the throat, causing severe pain.
  • Ulceration in mouth- A burst in the oral mucosa or the soft tissue in the mouth causes unbearable pain and irritation.
  • Difficulty eating- Eating is difficult for those with mouth sores since eating spicy and salty foods causes a burning feeling in the mouth. People, therefore, find it challenging to eat.

  • Mononucleosis – This is a disease caused by a viral infection. It leads to the problem of cold sores, which appear like tiny red spots or bruises-like areas inside your mouth, mostly on top of the mouth.
  • Folate deficiency – a condition where there isn’t sufficient folate in the body(folic acid), a type of vitamin B. This deficiency leads to mouth sores, causing a tingling sensation in the tongue. The tongue appears swollen and red around the edges if the folic acid deficiency is left untreated.
  • Anemia is a condition brought on by the body when there are not enough red blood cells to distribute oxygen. This issue may result in oral health issues like swollen gums, mouth sores, trouble eating, and an increased risk of developing mouth ulcers.
  • HIV/AIDS – HIV/AIDS patients are more prone to develop mouth sores due to the virus’s weakening of their immune systems. Canker sores and leukoplakia, which is a life-threatening risk, are caused by this condition.
  • Gastrointestinal issues – and a burning sensation in the mouth are caused by excessive stomach acid in the body, which can result in mouth sores from diseases including acid reflux, IBS, and GERD. Canker sores, which are white or pale-colored inside the mouth, are frequently the result of these problems.

To know the exact cause of minor mouth sores, you can diagnose it by its appearance and symptoms mentioned above, without any special test or doctor’s advice.

However, it is advised to consult a doctor or a dentist to know the underlying reason for major mouth sores that have not healed even after two weeks. To help you receive effective treatment, they will carefully inspect the lining of your mouth and inquire about any other additional symptoms.

Furthermore, suppose the doctor thinks that mouth sores cause an underlying disease. In that case, a swab test, blood test, tissue sample, or oral cavity biopsy is conducted as per the requirements and procedures.

6. Treatment

Minor mouth sores heal independently in a week or two, so treatment is unnecessary. However, major, painful sores frequently require medical care. There are numerous options available, including:-

  1. For severe canker sores, oral medicines reduce pain and promote faster healing. Patients are treated with drugs such as benzocaine and other steroids.
  2. If you have major mouth sores, your doctor may prescribe a mouth rinse named Orajel or other antiseptic gels like Orasore gel or peroxyl to reduce inflammation and pain in the mouth.

Rinse your mouth with slightly salted warm water to shrink the size of sores in your mouth, thereby relieving pain.
