Oral Paresthesia: Definition and Causes
Oral paresthesia is an abnormal sensation in the mouth, such as tingling, numbness, or burning, often described as mouth-tingling or loss of sensitivity. It can be caused by nerve injury during dental procedures (like tooth extraction, implant placement, or endodontic treatment), local or systemic diseases, psychogenic factors (such as anxiety or depression), or even as a rare side effect of vaccinations 3456789.
Oral Paresthesia After Dental Procedures
Dental procedures, especially those involving the mandibular (lower jaw) region, are a common cause of oral paresthesia. The inferior alveolar and lingual nerves are most at risk during surgeries like third molar (wisdom tooth) extraction, implant placement, and endodontic treatments. Paresthesia can be temporary or permanent, and its occurrence can significantly affect a patient’s quality of life 56789.
Oral Paresthesia and COVID-19 Vaccination
Oral paresthesia has been reported as a rare adverse event following COVID-19 vaccination. It is the most commonly reported oral adverse event after COVID-19 vaccines, followed by symptoms like lip swelling and taste disturbances. These events are more frequently reported in females, older adults, and recipients of mRNA-based vaccines. While the pattern of oral adverse events is similar to that seen with influenza vaccines, certain symptoms—such as taste changes and dry mouth—are more common after COVID-19 vaccination 310.
Psychogenic Oral Paresthesia
Psychogenic oral paresthesia is a form of the condition where the symptoms are linked to psychological factors, such as anxiety or depression, rather than physical nerve injury. Establishing a trusting relationship with the patient, providing explanations, and sometimes psychotherapy or psychiatric treatment can help resolve symptoms. Antidepressant medications may also be effective in some cases 14.
Diagnosis and Monitoring
Diagnosis of oral paresthesia involves clinical evaluation and, when necessary, imaging techniques like cone-beam computed tomography (CBCT) to assess nerve involvement and monitor recovery, especially in cases related to dental infections or procedures .
Treatment Modalities for Oral Paresthesia
Observation and Spontaneous Recovery
Some cases of oral paresthesia, especially those resulting from mild nerve injury, may resolve on their own with time and observation 78.
Pharmacological and Supportive Therapies
Medications such as vitamin B12, corticosteroids, antidepressants, and neurotropic agents have been used to accelerate nerve recovery and manage symptoms, particularly in cases with underlying systemic or psychogenic causes 478.
Low-Level Laser Therapy (Photobiomodulation)
Low-level laser therapy (LLLT), also known as photobiomodulation, is increasingly used to treat oral paresthesia. Clinical trials and case reports show that LLLT can improve sensory recovery after nerve injury from dental procedures. Different laser protocols have been used, but most studies report varying degrees of improvement in sensation, sometimes leading to complete recovery. However, more research is needed to establish standardized protocols and confirm long-term effectiveness 25678.
Other Physical Therapies
Other supportive treatments include physiologic therapies such as cryotherapy, heat therapy, massage, acupuncture, and electro-iontophoresis, which may help in some cases .
Conclusion
Oral paresthesia is a multifactorial condition that can arise from dental procedures, psychological factors, or as a rare side effect of vaccinations. Diagnosis involves careful clinical assessment and sometimes imaging. Treatment options include observation, medications, psychotherapy, and especially low-level laser therapy, which shows promise for nerve recovery. While most cases improve with appropriate management, further research is needed to optimize treatment protocols and outcomes 25678.
