Understanding the Root Causes Behind Cracked Sides of the Mouth- A Comprehensive Guide

What causes cracked side of mouth?

The cracked side of the mouth, also known as angular cheilitis, is a common condition that can be caused by various factors. This article aims to explore the possible causes of this issue and provide some tips on how to prevent and treat it.

1. Nutritional Deficiencies

One of the most common causes of cracked side of the mouth is nutritional deficiencies. A lack of essential nutrients, such as vitamin B12, iron, zinc, and riboflavin, can weaken the skin’s barrier and make it more susceptible to cracks. People with conditions like pernicious anemia, celiac disease, or Crohn’s disease may be more prone to this issue due to their inability to absorb these nutrients properly.

2. Dryness and Excessive Saliva Production

Dryness and excessive saliva production can also contribute to cracked sides of the mouth. Dryness can be caused by factors such as dehydration, cold weather, or air conditioning. Excessive saliva production can occur due to conditions like Sjögren’s syndrome, a chronic autoimmune disorder that affects the glands responsible for producing tears and saliva.

3. Allergies and irritants

Allergies and irritants, such as soaps, toothpaste, lip balms, or even the skin’s natural oils, can cause irritation and lead to cracked sides of the mouth. This condition is known as allergic contact cheilitis and can be triggered by substances that come into contact with the skin around the mouth.

4. Infections

Infections, such as cold sores or candidiasis, can also lead to cracked sides of the mouth. Cold sores are caused by the herpes simplex virus and can cause painful blisters around the mouth. Candidiasis, also known as oral thrush, is a fungal infection that can affect the mouth, including the corners.

5. Chronic skin conditions

Chronic skin conditions, such as eczema or psoriasis, can also contribute to cracked sides of the mouth. These conditions cause inflammation and dryness, which can lead to cracks and fissures.

Prevention and Treatment

To prevent and treat cracked sides of the mouth, consider the following tips:

1. Maintain a balanced diet rich in essential nutrients, including vitamins B12, iron, zinc, and riboflavin.
2. Stay hydrated and use a humidifier to keep the air moist, especially during cold weather or when using air conditioning.
3. Avoid allergens and irritants by testing different lip balms, toothpaste, and soaps.
4. Treat underlying infections, such as cold sores or candidiasis, with appropriate medications.
5. Use gentle, soothing lip balms and moisturizers to keep the skin around the mouth hydrated and protected.

By addressing the underlying causes and taking appropriate preventive measures, you can help alleviate the discomfort and appearance of cracked sides of the mouth.
