Cracked Corners of Mouth

Nicks J
Cracked corners of mouth can occur due to a number of reasons, including excessive exposure to sun and improper diet.

Dos and Don'ts

Smile, talk and laugh only if necessary as these actions can worsen the pain and prolong the healing of cracked corners of the lips.
Cracked mouth corners are quite painful and the discomfort aggravates while opening and closing the mouth. The sides of the mouth appear swollen and red. The presence of unsightly cracks makes it difficult to use cosmetic products and attend social gatherings. However, cracked lips can easily treated with simple home remedies that guarantee immediate relief.


Inadequate Water Intake and Poor Diet

People who consume less water and follow a diet, devoid of essential vitamins and minerals are likely to show cracked lip corners. Deficiency of vitamin B2, zinc and iron can lead to lips cracking at the corners.


In harsh weather, lips lose their moisture and become dry. No wonder, people in winter and summer season tend to develop cracks at the sides of the mouth.


Also referred to as angular cheilitis, this is a fungal or a bacterial infection that strikes the corners of the lip area. Cracks and lesions forming at the sides of the mouth is the most common symptom of this infection.

Oral Herpes

Contracting herpes infection can also cause cracks at the corners of the lips. Although herpes virus usually affects the genital areas, many times its symptoms are noticed at the corners of the mouth, indicating oral herpes. Generally, the cracks are observed at one side of the mouth.

Skin Irritants

The toothpaste that you are using everyday can also be the culprit behind cracking of lip corners. Lips, especially the corners often get exposed to toothpaste foam while brushing. Toothpaste ingredients such as sodium lauryl sulfate are known to irritate the lips. So, avoiding toothpaste that contain these skin irritants may help to resolve the issue.

Breathing Through Mouth

Mouth breathing is yet another reason why cracks develop at the sides of the mouth. The continuous flow of air in and out of mouth during breathing can make the lips excessively dry and chapped. People sleeping at night with mouth open often notice cracked lip corners in the morning.

Wrong Habits

The habit of licking the lips frequently leads to build up of moisture at the corners of the mouth. As a result, these areas of the mouth become infection breeding sites. No wonder, cracks eventually develop at the corners of the mouth.
The habit of biting the corners of the lips often, causes them to crack. Poorly fitting dentures or ignoring to clean the dentures everyday compromises oral health. This may also cause an infection and eventually lead to lip corners being cut.


Apart from drinking plenty of water and following a healthy diet, patients may benefit by using some common remedies, given below:

Prescription Creams

Topical antifungal ointments may be prescribed for fungal angular cheilitis. If herpes simplex virus is the reason for cracked corners, topical antivirals such as acyclovir cream may be recommended. These medications stop the proliferation of virus, which helps to shorten the duration of herpes outbreak.

Petroleum Jelly

Regularly applying petroleum jelly just before hitting the sack can wok wonders to get rid of cracks formed at the corners of the mouth. It is tried and tested remedy to soothe chapped corners of the mouth. Avoid using Carmex cream because it can dry the mouth and aggravate the problem.
