Why does the corner of my mouth keep splitting

At times, the corners of our mouths become excessively dry and start cracking. Have you wondered what we call this condition? Well, it is a harrowing and uncomfortable oral disease known as cheilitis or angular cheilitis. Also known as perleche, this problem manifests in dry and inflamed mouth corners, lesions or fissures on the corners, and excruciating pain. Angular cheilitis may either be viral or bacterial, and the causative factors may be numerous. So first, let us find out the root causes of angular cheilitis and how to prevent them.

Causes of angular cheilitis

The two main causative factors of cheilitis are – external and internal factors. The condition’s external causes include allergic reactions to cosmetics or drugs and exposure to extreme heat or cold or the sun. This type of cheilitis can be termed contact cheilitis. The internal causes of cheilitis include oral infection, autoimmune disorders, vitamin deficiencies, and age-related factors. We must be mindful of the ingredients we put on our lips and inside our mouths. Therefore, patch testing lipsticks and other makeup products become crucial.

  1. Research reveals 90 percent of angular cheilitis is caused due to poor diet. Vitamin deficiency is the most common cause of cheilitis. The absence of vitamin B2 in the body slows down the metabolism of fats, proteins, and carbohydrates and decreases energy production.  
  2. Skipping meals can result in binge eating and stomach ulcers and rob the body of essential nutrients. As such, the susceptibility to be diagnosed with cheilitis increases. Therefore, timely meals can help in preventing cheilitis.
  3. Research has identified approximately 30 allergens in toothpaste, and they are common in most of the tubes available in the market. In addition, research shows that toothpaste is the second most typical cause of contact cheilitis after lipsticks. On the contrary, it is the commonest cause of cheilitis among males.
  4. Celiac diseases may be an underlying cause of cheilitis. It is a disease that adversely affects the digestive tract, and consequently, the capacity of your intestines to absorb nutrients is hampered. Therefore, angular cheilitis is a warning symptom of celiac diseases. 
  5. Dehydration is another leading causative factor of cheilitis. The absence of enough liquids in the body could reflect in the mouth as dry and cracked corners.
  6. We know that saliva is a warehouse of bacteria and viruses. Therefore, constant licking and biting of the lips may create an environment conducive to the escalation of bacteria and fungi and lead to problems like angular cheilitis. 

Ways to prevent cheilitis

Precaution is better than cure, and this statement has unrivaled affirmation in the area of dental health. So, it is better to be aware and follow the necessary steps to avoid the occurrence of cheilitis in the first place. If you bite or lick your lips often, you must get rid of that habit. You should avoid the prolonged use of lipsticks and lip liners. Eating vegetables and fruits abundant in vitamin A, vitamin B12, and zinc is necessary. Being particular of the products you use on your mouth and the foods you eat will go a long way.

And they hurt – like really hurt. It hurts to talk, smile, eat and oh, jeez, you’ll do anything to keep from yawning! Is it from the cold? Is it from chapped lips? And why doesn’t lip balm help? You, my friend, most likely have what’s called Angular Cheilitis (key-light-us). Unlike chapped lips, which are caused by dryness, Angular Cheilitis is a fungal infection which is why your lip balm isn’t doing a whole lot.

WHAT CAUSES ANGULAR CHEILITIS?

There are several causes or health issues that might make you more likely to get ANGULAR CHEILITIS –
  • Ill-fitting dentures
  • Loss of teeth
  • Dry Mouth or xerostomia
  • Uncontrolled Diabetes
  • Some Medications – like those used to treat acne or chemotherapy drugs
  • Autoimmune disorders – Sjogren’s syndrome, lupus, Crohn’s disease or ulcerative colitis
  • Nutritional deficiencies – lack of A or B vitamins or zinc or not enough iron (anemia)
  • Malnutrition – including from frequent vomiting, bulimia or anorexia nervosa

Additionally, people with Down syndrome and elderly people may have increased odds of having cracks in the corner of their mouth. People with Down syndrome have a lower than normal muscle tone which leads to their mouths being open and their tongue distended, which irritates their lips. Elderly people may have a compromised immune system which makes it harder for them to fight infections. Additionally, as we get older, we lose muscle strength which can cause the corners of the mouth to turn down and saliva to collect there. They also suffer from over-closure of the mouth due to the loss of teeth.  

HOW DO I TREAT ANGULAR CHEILITIS?

Having said all of that, you may not have any of these issues and still get cracked lips. So what can you do to treat it? If you think you have it, doctors recommend a 1-percent hydro cortisone cream along with an antifungal, you know, the over-the-counter stuff they use to treat athlete’s foot. You should definitely use them together since using just the hydro cortisone can decrease your immune system where it’s applied and make the infection even worse. If after a few weeks you’re still suffering from Angular Cheilitis, make an appointment with a dermatologist. You may need a stronger cortosteroid than you can get over the counter.  

CAN I AVOID GETTING CRACKED CORNERS ON MY MOUTH?

Once you’ve had it even for a short time, you’ll want to avoid getting it again at all costs. Here are some tips for keeping it at bay:
  • Use a petroleum jelly at night to keep a protective seal and avoid saliva pooling in the corners of your mouth
  • Stay hydrated – especially during the seemingly endless cold winter months to avoid dryness
  • Keep up with your oral hygiene. Brush and floss twice daily to keep your mouth clean and healthy and less likely to allow the fungus to grow
  • Try not to lick your lips. We often do that when our lips feel dry but that only makes them drier (use that lip balm/petroleum jelly instead)
  • Avoid sugar – if you repeatedly get Angular Cheilitis and eat a lot of sugar, cut back. Candida yeast loves sugar (don’t we all?) See if cutting back helps to ease the reappearance of your Angular Cheilitis.
If you’ve tried these solutions and are still having issues, it may be time to see your doctor. Even though Angular Cheilitis is a common disease, each individual needs their own specific care.You may have an immune system issue that needs to be addressed.   Finding the cause of your immune problem could help keep the cracks at bay.  In the meantime, follow these tips to minimize the discomfort in the corner of your mouth.

Why does the corner of my mouth split?

Saliva gets trapped and builds up in the corners of your mouth. When it dries, the skin in the area can crack. You may lick your lips often to soothe your cracked skin. The warmth and moisture in the corners of your mouth create the perfect conditions for fungus to grow and multiply -- and cause infection.

What heals cracks in corners of mouth?

You may want to consider applying petroleum jelly or coconut oil to the corners of your mouth, which can form a barrier from saliva. Also, using lip balm regularly can help prevent chapped, dry lips.

What vitamin deficiency causes corners of the mouth to crack?

B Vitamins Deficiency: specifically vitamin B-12 (Riboflavin) can cause cracked lips that have difficulty healing. Angular cheilitis is a severe and very uncomfortable lip condition in which cracks and sores are present in the skin at the corners of the mouth when there is a B vitamin deficiency.
