You’re more likely to get angular cheilitis if the corners of your mouth are moist a lot of the time. This might happen for many reasons, such as:
- You have braces.
- You wear dentures that don’t fit well.
- You lick your lips a lot.
- You have a lot of saliva.
- Your teeth are crooked, or your bite isn’t lined up correctly.
- You have sagging skin around your mouth from weight loss or age.
- You suck your thumb.
- You smoke.
- You don’t get enough nutrients, like vitamin B or iron.
