Torn Corners of the Mouth | Just annoying or Dangerous?

The medical term for torn corners of the mouth is "angular rhinitis." These are small cracks that, despite their size, are often quite painful, especially when they come into contact with food or toothpaste. If they are not treated, they can also become infected - in the worst case, the tears can become chronic. Therefore, it is important to treat them promptly.

Causes of the cracks

The causes can be of various kinds. For example:
⦁ Dry heated rooms in winter
⦁ Colds
⦁ Iron deficiency
⦁ Zinc deficiency
⦁ Vitamin deficiency
⦁ Bacterial infections, e.g., streptococci
⦁ Viral infections, e.g., herpes
⦁ Fungal infections, e.g., Candida yeast
⦁ diabetes
⦁ Immune diseases
⦁ Skin conditions such as eczema
⦁ Allergies
All of these things cause the skin of the lips to become dry and chapped. If it is then irritated while eating or by opening the mouth wide, it will begin to tear. Eating and moving the mouth can make the cracks worse, causing inflammation and crusting. Bacteria or fungi may also settle in the wound and prevent it from healing.

Torn corners of the mouth as a warning sign

In principle, anyone can be affected by torn corners of the mouth. They usually heal on their own. Dry lips are not uncommon, especially during a cold or in winter. However, if the cracks do not heal permanently or if additional symptoms occur, you should consult a doctor. They will ask you

A precise assessment and a smear can also be used to check whether bacteria, viruses, or fungi have already infected the torn wound corners. Deficiency symptoms can be excluded as a cause by blood count. If dental problems are known, or a prosthesis is available, a dentist's clarification can be useful.

A lack of trace elements or vitamins is often to blame for the appearance of corners of the mouth. In many cases, it is caused by an iron deficiency. In particular, women are at risk of iron deficiency due to the loss of blood during menstruation. Widespread eating habits such as a vegetarian diet or following a diet can also lead to insufficient iron in the body. Diffuse symptoms such as tiredness, rapid exhaustion, headaches, and chapped lips occur here. The cause of an iron deficiency should definitely be clarified because dangerous internal diseases such as gastrointestinal ulcers can also cause it.
