Hello doctor,

I have white lines near the teeth on the lower lip which appears and goes by their own. But sometimes it hurts.

Welcome to

It could be lichen planus. It does not go off on wiping. If it goes off on wiping, then it is candida. Your case does not support submucous fibrosis as there is no blanching. My provisional diagnosis is lichen planus.

The Probable causes:

History of smoking.

Investigations to be done:


Differential diagnosis:

Candida, leukoplakia, and submucous fibrosis.

Probable diagnosis:

Lichen planus.

Treatment plan:

Biopsy (nearest dental hospital) and follow-up with a specialist.

Preventive measures:

Nicotine patch to stop smoking.
