I have noticed white granules on my lips for several weeks now, and this has been going on for several years. Sometimes I also feel itching. What could be the problem?

White particles appearing on the lips may be caused by oral candidiasis, oral lichen planus, abnormal keratinization of the oral mucosa, or scarring resulting from the healing process after a herpes simplex virus infection.

Patients should maintain regular oral hygiene by brushing teeth regularly and using a mild mouthwash, while avoiding oral care products that are irritating. Moisturizing products such as lip balm can be used. Additionally, maintaining a balanced diet and consuming more fresh vegetables and fruits to obtain adequate vitamins and trace elements is recommended. As the symptoms have persisted for several years and recently worsened, it is advised that the patient promptly consult a dermatologist or dentist for professional examination and diagnosis. The physician may recommend tests such as fungal culture or histopathological biopsy to determine the exact cause and provide targeted treatment.
