How to care for cracked corners of the mouth

If you’ve ever experience cracked sore corners around your mouth, you’ll know how uncomfortable it can be. From bleeding, blistering, swelling and crustiness, it can appear in a number of ways and also make the lips feel uncomfortable and dry. In some of the most severe cases, you may even experience a burning sensation on your lips or have an unpleasant taste in your mouth.

Here we take a look at some of the causes and treatments of cracked, sore corners of the mouth to help you address it as quickly as possible.


Cracked corners of the mouth are generally caused by a build-up of saliva that dries and then creates irritation. This warm, moist environment can also make the perfect breeding ground for yeast infections which can cause discomfort.

There are a few different reasons why saliva gets trapped in the corners of your mouth such as dentures, braces, smoking, sagging skin and even crooked teeth. Diabetes can also put you more at risk, as well as being deficient in vitamin B and iron. This may explain why it often occurs when you’re feeling run down or are getting over an illness.


When you feel soreness start to appear around your mouth, the most effective way of soothing it is with a moisturising lip balm. This creates both a physical and biological barrier around the mouth and lips while also preventing any future chapping.

La Roche-Posay Cicaplast Baume Lips is suitable for anyone with extreme dryness around their mouth. It’s also formulated with minimal ingredients and fragrance so it can be used on even the most sensitive of skin.

If you think that you may have a more severe case and a fungal infection, you’ll need to book an appointment with your GP for further treatment and advice.
