Evaluation and Management of Cheek Tingling (Facial Paresthesia)
Primary Neuropathic Etiologies
Cheek tingling is most often due to neuropathic disorders of the trigeminal nerve, principally post‑traumatic trigeminal neuropathy, post‑herpetic neuralgia, and burning‑mouth syndrome; serious causes such as malignancy and vascular dissection must be ruled out. 1
Dental procedures (e.g., root‑canal therapy, extractions, implants) are a leading precipitant of post‑traumatic trigeminal neuropathy by injuring branches of the trigeminal nerve. 2
Symptoms of post‑traumatic trigeminal neuropathy typically emerge within 3–6 months after the injury and present as a continuous burning or tingling sensation. 1
Post‑traumatic neuropathy frequently co‑exists with allodynia or other sensory alterations in the affected nerve distribution. 3
A history of inadequate analgesia during the dental procedure may signal the onset of neuropathic cheek symptoms. 2
Post‑herpetic neuralgia appears at the site of a prior facial herpes‑zoster outbreak and is characterized by continuous burning, tingling, itching, or tenderness that is moderate‑to‑severe and worsened by light touch or eating. 1
Allodynia and hyperalgesia commonly accompany post‑herpetic neuralgia in the affected facial region. 3
Burning‑mouth syndrome predominantly affects peri‑ and post‑menopausal women and manifests as burning, stinging, or itchy sensations most often on the tongue but also on the lips, palate, and cheek, with a normal‑appearing oral mucosa. 2
Burning‑mouth syndrome reflects peripheral nerve fiber dysfunction together with central brain changes and is frequently associated with xerostomia, altered taste, depressive symptoms, and reduced quality of life. 3
Red‑Flag Conditions Requiring Exclusion
Malignancy can present as a progressive neuropathic facial pain with tingling or numbness and must be excluded in any worsening cheek paresthesia. 4
Giant‑cell arteritis should be considered in patients older than 50 years; typical features include temporal region pain, jaw claudication, visual disturbances, and scalp tenderness. 6
Immediate high‑dose corticosteroid therapy (≥ 40 mg prednisone daily) for at least 2 weeks is required in suspected giant‑cell arteritis to prevent irreversible vision loss. 6
Diagnostic Work‑up
Obtain a comprehensive history emphasizing recent dental work, facial trauma, prior herpes‑zoster infection, and age > 50 years. 8
Perform computed tomography or magnetic resonance imaging when a structural lesion (e.g., tumor, vascular dissection) is suspected. 1
Conduct mechanocceptive and nociceptive sensory testing to identify allodynia or dysesthesia. 1
In patients > 50 years, order erythrocyte sedimentation rate and temporal‑artery assessment to rule out giant‑cell arteritis. 6
Use qualitative sensory testing to document the presence and extent of sensory abnormalities. 3
MRI is the preferred imaging modality for evaluating neuropathic facial symptoms to exclude tumors and vascular lesions. 7
Atypical Trigeminal Neuralgia and Post‑Stroke Facial Pain
Atypical (Type 2) trigeminal neuralgia may present with prolonged burning or aching pain between classic electric‑shock attacks, usually unilateral and involving the second and third trigeminal divisions. 6
Typical triggers include light touch, washing, cold wind, eating, or tooth‑brushing. 7
Post‑stroke facial pain occurs on the same side as the cerebral infarct and is described as continuous aching or burning with dysesthesia, often aggravated by tactile stimulation. 6
