Pins and needles, numbness, burning pain or taste changes after dental work can be frightening. If these symptoms follow an extraction, implant placement or local anaesthetic, you may be dealing with an injury to the lingual nerve or the inferior alveolar nerve. Some people recover within weeks; others live with persistent altered sensation that affects eating, speaking and quality of life.
This guide explains how these injuries happen, how they are diagnosed, when they may amount to negligence, and what evidence supports a claim. It also sets out practical next steps you can take today and how specialist legal support can help you secure compensation to fund treatment and ease financial strain.
If your symptoms are severe or worsening, seek urgent clinical care first via NHS 111 or an emergency dental service. Once safe, consider the guidance below.
What are lingual and inferior alveolar nerve injuries?
Two nerves are commonly affected during dental procedures:
- Lingual nerve: provides sensation to the tongue and taste to the front two thirds.
- Inferior alveolar nerve (IAN): runs within the lower jaw, supplying feeling to the lower teeth, chin and lower lip.
Injuries can arise during lower wisdom tooth extractions, implant drilling or placement in the lower jaw, difficult root canal treatments, or from local anaesthetic injections. Symptoms include numbness, tingling, pins and needles, burning or electric-shock pain, drooling, biting the tongue or lip unknowingly, speech changes and taste disturbance.
Some injuries are temporary neurapraxia that improves over weeks. Others involve partial or complete nerve disruption and can persist indefinitely.
How nerve damage is proven: the diagnosis pathway
Proving dental nerve damage relies on clinical records and objective testing, alongside your own account of symptoms. A typical pathway includes:
- Dental records: treatment notes, consent forms, referral letters and post-operative advice. These show what was planned, what was discussed and what was done.
- Imaging: periapical x-rays, panoramic x-rays (OPG), and cone beam CT (CBCT). For extractions and implants, CBCT helps demonstrate proximity to the IAN canal and any breach. Post-injury imaging can show implant position, over-instrumentation, or bony defects.
- Neurosensory testing: clinicians may document light touch, pin-prick, two-point discrimination, thermal testing and taste tests. Consistent deficits support the diagnosis and help map severity.
- Specialist assessment: oral and maxillofacial surgeons or neurologists may assess the injury, advise on prognosis and consider surgical options such as nerve exploration or repair in the early months.
- Symptom timeline: your contemporaneous notes on onset, progression and triggers are powerful corroboration.
With your authority, we obtain and organise these materials, then instruct an independent dental expert to report on breach of duty, causation and prognosis.
Risk versus negligence: when is a dentist liable?
Not every nerve injury is negligent. Some procedures carry a recognised risk even when performed with reasonable care. A dentist may be liable if their care fell below a reasonable standard and that failing caused the injury. Examples include:
- Inadequate planning and imaging before implant placement, leading to an implant drilling into or compressing the IAN canal.
- Excessive force or poor technique during an extraction, especially a lower wisdom tooth closely related to the nerve, without appropriate sectioning or referral.
- Over-instrumentation or overfilling during root canal treatment with extrusion into the mandibular canal.
- Anaesthetic needle trauma where avoidable technique errors are evident.
- Consent failures, where material risks and reasonable alternatives were not explained in a way a reasonable person in your position would find significant.
By contrast, if the risk was inherent, the technique was reasonable, the nerve was known to be close and valid consent was obtained, liability may not be established. Independent expert opinion is central to this analysis.
Informed consent requirements
Valid consent is more than a signature. UK law requires tailored discussion of:
- Material risks relevant to you, including the specific risk of temporary or permanent nerve injury in lower extractions and implant procedures.
- Reasonable alternatives, such as coronectomy, staged treatment, referral to a specialist, or doing nothing with monitoring.
- Likely outcomes, aftercare and costs.
If a dentist did not provide adequate, patient-specific information and obtain informed consent, this can amount to negligence even when the technical work was competent. We review what was recorded and what you recall was discussed to assess consent.
Limitation periods: how long do you have?
In England and Wales, you generally have three years from the date of the treatment or from the date you first knew, or could reasonably have known, that your injury may be due to negligent care. For children, the limitation clock usually runs from their 18th birthday and a litigation friend can act beforehand. Because evidence can degrade and deadlines are strict, early advice is essential.
What compensation can cover
Compensation aims to put you, as far as money can, back in the position you would have been in. For nerve injuries this can include:
- Pain, suffering and loss of amenity, reflecting the severity and persistence of symptoms.
- Remedial or future dental and medical treatment costs, including nerve consultations, pain management, implants or prosthetics if teeth were lost, and therapy.
- Out-of-pocket expenses, such as travel, medication and aids to manage symptoms.
- Loss of earnings or reduced capacity where symptoms affect work.
Indicative outcomes vary widely. Persistent lingual or IAN injury with ongoing dysaesthesia and functional impact has produced awards in the hundreds of thousands of pounds in some scenarios. Your prognosis, evidence and losses will determine the valuation.
Practical next steps you can take today
- Keep a simple symptom diary. Note dates, sensations, triggers and impact on daily life.
- Gather receipts. Keep proof of any dental fees, travel, medication, specialist consultations and time off work.
- Request your records. Ask all treating providers for your full dental notes, consent forms, x-rays and any CBCT scans.
- Take clear photos. If relevant, photograph swelling, ulceration or bite injuries to tongue or lip.
- Seek timely clinical review. Follow up with your dentist or GP, and request referral to an oral and maxillofacial surgeon if symptoms persist beyond a few weeks.
- Contact us for a free assessment. We offer a confidential eligibility review and can request records on your behalf.

Short FAQ
- How do you prove dental nerve damage?
Through contemporaneous symptoms, documented neurosensory testing, imaging such as OPG and CBCT, and consistent dental records. Independent expert opinion links any breach of duty to your injury.
- Is a dentist liable for nerve damage?
Sometimes. Liability arises where the standard of care fell below that of a reasonably competent practitioner and caused the injury, or where informed consent was inadequate. Some nerve injuries are recognised risks even with reasonable care.
- What is the hardest injury to prove?
Chronic neuropathic pain without clear imaging findings can be challenging. Robust neurosensory testing, specialist reports and a detailed symptom diary are vital.
- Can I sue for dental nerve damage?
Yes, if negligence and causation can be established within the limitation period. A specialist solicitor can assess eligibility and advise on next steps.
- How much compensation for dental nerve damage?
Amounts vary. Persistent lingual or IAN injuries with significant ongoing symptoms have led to substantial awards. Your prognosis, functional impact and financial losses determine the valuation.
