What are the reasons for the baby's mouth becoming dirty

Patient's question:

No

Doctor's answer:

In your case, it might be chronic cheilitis. The cause of chronic cheilitis is not very clear, and it may be related to cold, dry seasons, smoking, alcohol, excessively hot food, licking lips, biting lips, and other bad habits. Sometimes it may also be related to psychological factors. You can use a decoction of Sophora flavescens to apply externally for treatment, which may have a certain effect.
