Nerve Damage After Root Canal Claims Solicitors in Manchester

Contact Us Today

A root canal is supposed to save your tooth, not leave you with nerve damage. If your pain or numbness hasn’t settled weeks after your root canal, or things just don’t feel right in your jaw, lip, or tongue, something may have gone wrong. 

Root canal nerve damage can happen due to poor technique or the careless use of cleaning solutions during the procedure. 

When you suffer nerve damage after a root canal as a result of negligence, you may have the right to claim compensation. Contact TJL or call us on 0161 877 1066 for free advice on whether you have a claim.

Is it normal to have nerve pain after a root canal?

Yes, it can be. Discomfort in the days following a root canal is expected. The area around the tooth has been worked on, and some tenderness or sensitivity is a normal part of healing. But what isn’t normal is pain or altered sensation that gets worse rather than better, or that persists past two to three weeks. 

Nerve pain after root canal treatment that lingers or changes is a warning sign. Numbness in your lip or chin, burning, or tingling that doesn’t settle aren’t normal post-treatment side effects. If you experience these symptoms, the nerves surrounding the tooth may have been disturbed or damaged during the procedure.

What are the symptoms of nerve damage after root canal treatment?

  • Persistent numbness or loss of feeling in the lower lip, chin, tongue, or gum
  • A burning or electric sensation in the jaw or mouth
  • Tingling or pins and needles around the treated area
  • Unusual sensitivity to temperature or touch in teeth near the treated tooth
  • Difficulty eating, drinking, or speaking comfortably
  • Pain that spreads to the jaw, cheek, or ear

What should you do if you think your root canal has caused nerve damage?

Act quickly. The sooner nerve damage is identified, the better your chances of recovery. Go back to your dentist and tell them exactly what symptoms you’re experiencing and when they started. Your dentist should document your concerns and refer you for specialist assessment if the symptoms don’t settle within a few days. 

If you feel your concerns aren’t being taken seriously, you can ask your GP for a referral to an oral and maxillofacial surgery department. An independent specialist can then examine the affected nerve and determine the likely cause of the damage. That assessment is also important evidence if you later decide to make a root canal nerve damage claim. 

Make sure you keep a written record of your symptoms from the start, including when they began, if they’ve changed, and how they’ve affected your daily life. 

How does a root canal cause nerve damage?

There are three main ways a root canal nerve injury can occur
  1. Over-instrumentation. During a root canal, your dentist uses files to clean the inside of the tooth’s root. If those files are pushed past the root tip, they can make direct contact with the inferior alveolar nerve. Even brief contact can cause lasting damage. 
  2. Chemical injury from sodium hypochlorite. Root canals are cleaned using an irrigant solution, typically sodium hypochlorite. Sodium hypochlorite nerve damage occurs when the solution escapes through the root tip into the surrounding tissue. It is highly toxic to nerve tissue. This type of injury usually causes immediate and intense pain at the time of treatment. 
  3. Overfilling. If the root canal sealant material is applied under pressure or in too large a quantity, it can push out through the root tip. It then compresses or chemically damages the inferior alveolar nerve running through the lower jaw.

In the lower back teeth, the root tips sit very close to the inferior alveolar nerve, which is why most root canal nerve injuries occur in this area.

Can a root canal damage a nerve permanently?

Yes, in some cases. The NHS confirms that nerve injury can cause temporary or permanent problems following dental procedures.

But whether the damage is permanent depends on how the nerve was injured and how quickly it was identified and treated. Where the nerve has only been bruised or briefly irritated, it may recover over weeks or months. 

If the injury was caused by sodium hypochlorite or overfilling material compressing the nerve, the damage is likely more serious. Permanent nerve damage after root canal treatment requires urgent specialist assessment. If your symptoms haven’t improved after several months and you can’t get any answers, speak to our solicitors about your options.

When does root canal nerve damage amount to negligence?

Root canals carry a small but well-recognised risk of nerve injury.

That means if you experience a nerve injury, your dentist wasn’t automatically negligent. What our solicitors assess is whether the risk was properly managed. When it wasn’t, it’s usually because of one of the following failures:

  • Pushing instruments past the root 
  • Using sodium hypochlorite incorrectly
  • Overfilling the canal causing sealant material to extrude through the root
  • Failing to take adequate X-rays before the root canal
  • Not warning you about the risk of nerve damage before you consented to treatment
  • Failing to identify or act on nerve damage symptoms after the procedure

Each of these failures can lead to a root canal negligence claim. Our solicitors will review your records and tell you honestly whether you have a valid claim.

Can you claim for nerve damage after root canal treatment?

Yes, where your root canal injury was caused by negligent care.

But you’ll need to show evidence that your dentist failed to meet the standard of a competent dental professional and that this failure caused your injury. Root canal nerve damage claims can be challenging to prove. The causes are often tricky to establish without expert analysis of your records and the timeline of your symptoms. Our solicitors work with independent dental experts who understand these cases well.

Pain After Dental Treatment: Could it Be a Sign of Negligence?

A little pain after dental work is normal, and most of it settles down within a few days. But if the pain lingers or gets worse, something may have gone wrong during treatment. And if your dentist made a mistake or treated you carelessly, you may have grounds for a legal claim.

How to Make a Personal Injury Claim

Most personal injury claims follow a similar process, whether you were hurt at work, in a road traffic accident, while cycling, or in a public place. But no two claims are exactly the same.

What Counts as a Personal Injury Claim?

A personal injury claim can arise when someone else’s negligence causes your injury. This could be a careless driver, an employer, or a business that failed to fix a dangerous condition. But whether you have grounds to make a claim depends on how the accident happened and who is responsible. Not every accident necessarily leads to a valid personal injury claim.

Is there a time limit for making a root canal nerve damage claim?

Yes, and don’t leave it too long.

Under the Limitation Act 1980, you have three years to bring a dental negligence claim, starting from the date of your root canal. If you only realised later that the procedure caused your symptoms, the clock may start from that point instead. 

One exception worth knowing: if you were under 18 when the treatment took place, you have until your 21st birthday to make a claim. Root canal nerve damage cases can take time to investigate properly, so the earlier you get legal advice and start gathering evidence, the better.

What is a root canal nerve damage claim worth?

Every root canal nerve damage claim is unique. What you receive depends on how serious your injury is and whether it’s likely to be permanent. The more your symptoms have affected your daily life, the higher your compensation is likely to be.

When TJL Solicitors assess your claim, they look at the entire impact of a nerve injury on your life, including:

  • Pain, suffering, and reduced quality of life
  • Your ability to eat, drink, speak, and carry out daily activities
  • Any anxiety, loss of confidence, or psychological distress
  • The cost of any further treatment you’re likely to need
  • Lost wages as a result of the injury
  • Out-of-pocket expenses linked to the negligent procedure

Once we have the full picture, we can give you a realistic view of what your claim could be worth.
