The primary signs and symptoms of oral lichen planus are the lesions affecting the mucous membranes of the mouth.

The lesions may appear as:

- Lacy, white, raised patches of tissues

- Red, swollen, tender patches of tissues

- Open sores

The lesions may appear on the inside of the cheeks, gums, tongue, inner tissues of the lips, the throat or the esophagus.

The red, inflamed lesions and open sores of oral lichen planus can cause a burning sensation or pain. The white, lacy patches alone usually don't cause discomfort, except when they appear on the tongue.

Other signs or symptoms may include:

- A metallic taste or a blunted taste sensation if the tongue is affected
- Dry mouth
- Difficulty swallowing if the throat or esophagus is affected
- Sensitivity to hot or spicy foods
- Bleeding and irritation with tooth brushing
