MOUTH ULCERS: How to Spot, Treat, and Prevent them?

Mouth Ulcers




Do you know about Canker’s sores?? Sounds very unfamiliar right?

How about an ulcer? Yes, it’s the same. Canker sores are also called mouth ulcers.

You wake up to a bright morning and your mouth alarms you of an ulcer.

But, what is an ulcer — I mean mouth ulcer or oral ulcer.

Mouth ulcers look like small swollen red boils with white or yellow patches on them. They are mostly found on the inside of your mouth, be it on your lips, inner cheek, tongue, or even on the palate.

The white or yellow patch is basically a result of the removal of the topmost layer of skin.

How does that form now?— it is called the cause of mouth ulcers.


It can form on 3 conditions:-

1) An accidental bite or a physical injury of the mouth during eating something, while wearing dental braces, or due to harsh brushing activities, and so on.

Let’s say you accidentally bite your lips or inner cheek. Alongside, your skin might also shed off. So, the shedding of the skin in that particular region exposes the inner skin on the outside.

This inner skin acts as a nutritive media for many breeding bacteria, fungi, and viruses causing bacterial, fungal, and viral ulcer infections. Now, this is what makes it look like swollen white and yellow patches.

2) Due to the internal factors of our body

Hormonal fluctuations in women during their menstruation, depression, stress, loss of appetite, lack of sleep, and deficiency of vitamin B12, zinc, folate, and iron can also cause ulcers.

3) Due to the products that we use which come in contact with our mouth

That is, any kind of sensitivity to sodium lauryl sulfate that is present in most of the toothpaste and mouth rinsing liquids that we use on day to day basis can trigger mouth ulcers.

But, apart from all of this, something that is very important to be known is that mouth ulcers solely as an infection is not dangerous to one’s life at all.

4) Psychological conditions like Stress and Anxiety can also cause mouth ulcers.

But yes, it can be an extracurricular symptom for major diseases like—

1) Diabetes— on lack of insulin.

2) Inflammatory bowel disease — Inflammation in the digestive tracts of the small intestine or large intestine

3) Decline of immunity

4) Celiac disease — Inflammation in the small intestine which thereby arrests the absorption of nutrients into the body system.

5) Behcet’s disease — Inflammation in blood vessels.

6) HIV AIDS — It is a deadly immune deficiency syndrome.

Also, the substantial fact to it is that—

Today, mouth ulcers are common among 20% of the people living.


Mouth ulcers appear in a day and would persist for many days, weeks, and sometimes even for months together depending on their severity.



INCREASED SENSITIVITY and INTOLERANCE TO SALT / SPICES are the main and the most common symptoms of Mouth ulcers.
