What Causes Cracks in Corner of Mouth

So, we now know that the cracks in the corner of the mouth are called angular cheilitis. But what causes angular cheilitis? What are the things that lead to those cracks in the corners of your mouth?

There are a few causes of angular cheilitis.

1. Saliva

It may seem odd, but yes, your own saliva can cause the cracks in the corner of the mouth. The moisture from saliva gets trapped in those corners and becomes fertile ground for fungus and bacteria. This can be a common issue for people with braces or dentures.

2. Fungus

It may seem gross and brings to mind images of small mushrooms growing out of your face but it’s true, angular cheilitis is usually a result of a fungal infection. In particular, it’s caused by a yeast called Candida. Parents might recognize Candida as the fungal infection that causes diaper rash in babies.

3. Bacterial Infection

As noted above, trapped saliva can attract bacteria that can cause the cracks and slight blistering at the corner of your mouth.

4. Dehydration

The cracking at the corners of your mouth might just be due to dehydration. If you don’t get enough fluid into your system, your skin can start to dry out a little, including the corners of your mouth.

Now that you know what causes the cracks in the corner of the mouth, it’s time to look at what you can do to try to treat them.

How to Treat Cracks in Corner of Mouth

While angular cheilitis can be kind of gross to have or to look at, luckily, there are some medical options for you to use to get those pesky cracks to go away.

1. Anti-Fungal Cream

As we noticed in the previous section, the most prevalent cause of angular cheilitis is a fungal infection. Luckily, there are some over-the-counter anti-fungal creams that can help clear up the fungal infection. If the infection is particularly stubborn, there are prescription creams that can help move the fungus out of the corners of the mouth.

2. Zinc Oxide Paste

Zinc oxide paste can help repair the damage of the cracked corners of your mouth. It works especially well if the damage is a result of dehydration.

3. Good Oral Hygiene

A lot of the bacteria that can cause angular cheilitis originates in the mouth. To combat this, just keep up good oral hygiene. If you brush and floss properly and use mouthwash, it will eliminate a lot of the bacteria that will cause the cracks in the corners of the mouth.

Also, make sure your dentures fit properly. Poor fitting dentures can lead to excess saliva mucking up the corners of your mouth, leading to angular cheilitis.

4. Petroleum Jelly

If the corners of your mouth are cracking due to dehydration or your mouth drying out, using a little bit of petroleum jelly in the corners can help. The jelly locks moisture into those areas, as well as helps heal and prevent the cracking in the corners.

While these medical means can help you clean out the cracked corners of mouth causes, there are several natural remedies that can help you with your angular cheilitis.
