mouth ulcers

Mouth ulcers are a common oral problem that most of us might have experienced. There are times when you get up in the morning and spot a white, yellow or red painful ulcer in your mouth. It is clinically known as aphthous ulcers, which is derived from a Greek word “aphtha” which means ulceration. Most of the mouth ulcers can be due to poor oral hygiene or lack of nutrients but it can also be triggered by hormonal imbalance or an underlying condition such as Crohn’s disease.

What causes ulcers in the mouth?

Mouth ulcers can be caused by an infection, injury, or allergic reaction. In most cases, the exact cause of the mouth ulcers is unknown. Here are some common and known causes of mouth ulcers.

Poor oral hygiene: Lack of proper oral hygiene is one of the most common and preventable causes of mouth ulcers. Factors such as not brushing the teeth properly or excessive brushing can also cause mouth sores. Moreover, the presence of certain ingredients such as sodium lauryl sulphate in the toothpaste or mouthwash can trigger an allergic reaction and increase the risk of recurrent mouth ulcers.

Certain medicines: In some cases, medicines used to treat certain health problems can cause mouth ulcers. These include antibiotics, painkillers, beta-blockers, iodides, and anticonvulsants. Also, radiation therapy and drugs used to treat cancer (chemotherapy drugs) can also lead to mouth ulcers.

Dental injury or implants: Yes, any injury to the oral cavity including teeth, gums, lips or cheeks can increase the risk of mouth ulcers. This can include cheek biting or lip biting habits or broken teeth. Also, use of dentures or braces which are not fitted properly can also cause mouth ulcers. Moreover, if you are allergic to any material or ingredients of the dental appliances such as nickel, then the chances of suffering from mouth ulcers is high.

Nutritional deficiencies: Diet plays a key role in ensuring overall health including the oral health. This is the reason why lack of certain nutrients in the body can cause mouth ulcers, including recurrent mouth ulcers. Nutritional deficiencies of common minerals and vitamins such as iron, vitamin B, and vitamin C can also cause one of the common causes of mouth ulcers. Hence, it is important to ensure proper intake of nutrients from diet and prevent the risk of mouth ulcers.

Tobacco use: It goes without saying that tobacco and smoking are injurious to health. Use of tobacco causes mouth ulcers due to the exposure of harmful chemicals and toxins present in it. These chemicals also affect the lining of the mouth and change the temperature and acidity of the mouth, further increasing the risk of infection. Moreover, the irritants present in tobacco can also increase your risk of oral and mouth cancer.

Infections: Mouth ulcers can be caused due to a weakened immune system or hormonal changes in the body following stress or anxiety. Whether it is due to bacterial, viral, or fungal infection or underlying systemic diseases, mouth ulcers do indicate a serious health problem. Some of the common medical conditions that can cause mouth sores are:

– Intestinal disease: Crohn’s disease, celiac disease, or inflammatory bowel disease

– Bacterial infections: Gonorrhea or syphilis

– Viral infections: Herpes, chickenpox, shingles, or human immunodeficiency virus (HIV) infection

– Fungal infections: Candida infection

When to see a doctor?

Mouth ulcers that accompany with certain symptoms such as fever, blisters on the skin or inflammation of the eyes, should not be left ignored. It is wise to consult a doctor if mouth ulcers are:

-Painful

-Recurrent

-Interfere while eating

-Interfere when swallowing food

If mouth sores last for more than 10 days, it is important to diagnose it and know the underlying causes of mouth ulcers as it could also be a sign of cancer.
