What is Angular Cheilitis?

Angular cheilitis is a condition characterized by inflammation, redness, and sometimes cracks or sores at the corners of the mouth. This condition can cause discomfort and pain, especially when eating, speaking, or smiling. It can be caused by a variety of factors, including infections, nutritional deficiencies, or other underlying health conditions. While angular cheilitis is typically not a serious medical condition, it can be persistent and may require treatment to prevent recurrence.

What Are the Symptoms of Angular Cheilitis?

The symptoms of angular cheilitis can vary depending on the severity of the condition and its underlying cause. The most common symptoms include:

1. Redness or Inflammation?

• The skin at the corners of the mouth becomes red, swollen, and inflamed.

2. Cracks or Fissures?

• Cracked skin or deep fissures may form at the corners of the mouth. These can sometimes bleed or become painful.

3. Soreness or Pain?

• The affected area can be sore, especially when moving the mouth, such as when eating or speaking.

4. Dryness?

• The skin may feel dry, flaky, or rough.

5. Bleeding?

• In severe cases, the cracks may bleed, especially if they become infected.

6. Itching or Burning Sensation?

• Some people experience itching, tingling, or a burning sensation in the affected area.

7. Pus or Discharge?

• If the condition is caused by an infection, there may be pus or discharge from the cracks.

What Causes Angular Cheilitis?

Angular cheilitis can be caused by various factors, often involving infections, nutritional deficiencies, or pre-existing medical conditions. Some common causes include:

1. Fungal Infections (Candida Albicans)?

• Candida is a type of yeast that can cause fungal infections. This is one of the most common causes of angular cheilitis. When there is an overgrowth of candida around the corners of the mouth, it can lead to cracks and sores.

2. Bacterial Infections?

• Staphylococcus aureus is a bacteria that can also cause angular cheilitis, often in combination with fungal infections.

3. Nutritional Deficiencies?

• A deficiency in vitamins such as iron, vitamin B12, or folic acid can make individuals more susceptible to developing angular cheilitis.

4. Dry or Chapped Skin?

• Chronic dry skin or lip licking can cause cracks in the corners of the mouth, leading to angular cheilitis. It’s especially common in people living in dry climates or during the winter months.

5. Poor Oral Hygiene?

• People who have poor oral hygiene or wear dentures that do not fit well are at higher risk of developing angular cheilitis.

6. Diabetes?

• Uncontrolled diabetes can lead to higher blood sugar levels, which in turn can promote fungal infections like candida.

7. Immune System Disorders?

• People with weakened immune systems, such as those with HIV/AIDS or other autoimmune diseases, are more prone to developing angular cheilitis.

8. Smoking?

• Smoking can irritate the skin around the mouth and contribute to the development of angular cheilitis.

9. Saliva Buildup?

• Excess saliva around the mouth, due to drooling or poorly fitted dentures, can cause the skin to become moist, promoting fungal or bacterial growth.

How is Angular Cheilitis Diagnosed?

Diagnosis of angular cheilitis is generally straightforward based on a physical examination and a review of your symptoms. However, to identify the exact cause and determine the best treatment, additional steps may be taken:

1. Medical History and Physical Examination?

• A healthcare provider will ask about your symptoms and medical history, including any history of dental problems, immune system disorders, or nutritional deficiencies. They will also examine the affected area for typical signs of angular cheilitis.

2. Laboratory Tests?

• If an infection is suspected, a sample of any discharge or pus may be taken for laboratory testing to identify whether the cause is fungal, bacterial, or viral.
• Blood tests may be recommended to check for nutritional deficiencies or underlying health conditions such as diabetes or immune system disorders.

3. Skin Biopsy?

• In rare cases, a skin biopsy may be performed to rule out other skin conditions or confirm the cause of the infection.

How is Angular Cheilitis Treated?

Treatment for angular cheilitis typically focuses on relieving symptoms and addressing the underlying cause. The following treatment options may be recommended:

1. Antifungal Medications?

• If the condition is caused by a fungal infection (candida), topical antifungal creams or oral antifungal medications, such as clotrimazole or fluconazole, may be prescribed.

2. Antibiotics?

• If bacterial infections are present, topical or oral antibiotics such as mupirocin or cephalexin may be needed to treat the infection.

3. Hydrocortisone Cream?

• Topical hydrocortisone cream may be used to reduce inflammation and alleviate itching or burning sensations, especially if there is significant swelling.

4. Vitamin Supplements?

• If the angular cheilitis is caused by a nutritional deficiency, supplements such as iron, vitamin B12, or folic acid may be prescribed to restore the necessary nutrients in your body.

5. Lip Balms and Moisturizers?

• Applying moisturizing lip balms or emollient creams can help keep the area hydrated and prevent further irritation or cracking.

6. Denture Adjustment?

• If you wear dentures, ensuring that they fit properly is important to avoid further irritation at the corners of the mouth.

7. Avoiding Irritants?

• Avoid licking the lips or using harsh products that can further dry out the skin.

8. Lifestyle Changes?

• In some cases, quitting smoking or improving oral hygiene can help prevent the recurrence of angular cheilitis.

9. Treating Underlying Conditions?

• For individuals with diabetes or other immune system disorders, better control of these conditions can help reduce the risk of developing angular cheilitis.

What Are the Potential Complications of Angular Cheilitis?

While angular cheilitis itself is usually not serious, it can lead to several complications if left untreated:

1. Chronic or Recurrent Infections?

• If the underlying cause (such as a fungal or bacterial infection) is not treated properly, the condition can recur or become chronic.

2. Scarring or Hyperpigmentation?

• Repeated infections or irritation may lead to scarring or darkening of the skin around the mouth.

3. Difficulty Eating or Speaking?

• Severe cases can make it painful to eat, speak, or smile, affecting daily life.

4. Spread of Infection?

• Infections, if left untreated, can spread to other parts of the body, including the lips or inside the mouth.

How Can Angular Cheilitis Be Prevented?

Although it may not always be possible to prevent angular cheilitis, the following steps can help reduce your risk:

1. Maintain Good Oral Hygiene?

• Brushing your teeth and gums regularly and keeping dentures clean can help prevent bacterial growth and reduce the risk of angular cheilitis.

2. Stay Hydrated?

• Drinking plenty of water and using a good lip balm can help prevent dry or cracked skin around the mouth.

3. Treat Nutritional Deficiencies?

• Ensure that you’re getting enough vitamins and minerals, especially iron, vitamin B12, and folic acid, to reduce the risk of developing angular cheilitis.

4. Avoid Excessive Lip Licking?

• Licking your lips can worsen irritation, so it’s important to avoid this habit.

5. Manage Chronic Conditions?

• Proper management of conditions such as diabetes and immune system disorders can help prevent the onset of angular cheilitis.
