Yes, dental implants can cause nerve damage, but it is an uncommon complication, and the risk is largely tied to how close the implant sits to a nerve. Most nerve injuries linked to implants involve the lower jaw, where a major sensory nerve runs through a canal inside the bone. When an implant or drill comes too close to that nerve, you may notice numbness, tingling, or pain in the lip, chin, gums, or teeth that lasts well past the time the local anesthetic should have worn off. Careful 3D planning lowers this risk considerably, and many nerve injuries improve over time.
If you fear your dental implant procedure has led to nerve damage, we strongly recommend you take action as soon as possible. Our team of oral surgeons at Legacy Oral Surgery treats nerve safety as a central part of implant planning, and we can evaluate symptoms that concern you after surgery.
Can Dental Implants Cause Nerve Damage?
Nerve injury happens when the nerve is touched, compressed, stretched, or irritated during or after the procedure. The most common cause is an implant or drill that extends too deep into the lower jaw and reaches the canal that holds the inferior alveolar nerve. Even when nothing touches the nerve directly, pressure from an implant sitting right next to the canal, bleeding inside the canal, or swelling in the surrounding tissue may disturb how the nerve sends signals.
Research shows how much distance matters. A 2025 systematic review and meta-analysis from researchers at the Harvard School of Dental Medicine looked at how far implants were placed from the mandibular canal. In the studies reviewed, implants placed at least 1 mm from the canal were not associated with sensory changes, while implants placed closer than 1 mm, or that entered the canal, were associated with sensory changes in a large share of patients. You can read the systematic review on inferior alveolar nerve damage and implant placement through the National Library of Medicine. The authors stressed careful preoperative planning and three-dimensional imaging as the main precautions.
Another systematic review of implant surgery in the lower jaw estimated that roughly 12% of patients may have some nerve-related sensory change in the first week after routine implant placement, dropping to about 5% at three months. Many early symptoms resolve, and a smaller group has longer-lasting changes. That review also found the rates were much higher when the nerve itself was surgically moved, a procedure we cover separately below. Details are in the review of neuropathic injury after mandibular implant surgery.
Which Nerves Can Be Affected by Dental Implants?
Several sensory nerves run close to the areas where implants are commonly placed. Which one is at risk depends mostly on where the implant goes.
The Inferior Alveolar Nerve
This nerve travels through a canal inside the lower jawbone, beneath the roots of the back teeth. It provides feeling to the lower teeth, and its branches supply the gums, lower lip, and chin on the same side. Because implants replacing lower molars and premolars sit directly above this canal, it is the nerve most often involved in implant-related injuries.
The Mental Nerve
The mental nerve is a branch of the inferior alveolar nerve that exits the jaw through a small opening called the mental foramen, usually near the lower premolars. In some people the nerve loops forward inside the bone before exiting, so implants and incisions in this area must account for it.
The Lingual Nerve
The lingual nerve runs along the tongue side of the lower jaw and provides feeling, and taste, to the front two-thirds of the tongue. It is not inside the bone, but it can be affected if a drill perforates the inner wall of the jaw or tongue-side tissue is stretched during surgery.
Nerves in the Upper Jaw
Nerve injury is much less common with upper jaw implants. The main anatomical concern in the back of the upper jaw is usually the sinus rather than a nerve, which is why some patients need a sinus lift before implants.
Signs and Symptoms of Nerve Damage After an Implant
Your lip, chin, and gums normally feel numb for several hours after surgery because of the local anesthetic. Nerve injury symptoms last beyond that window, usually on the same side as the implant, and may include:
- Persistent numbness: a lip, chin, or gum area that still feels numb the day after surgery, or a “dead” feeling when you touch your face.
- Tingling or pins and needles: a buzzing or crawling sensation, sometimes described as feeling like the anesthetic is wearing off but never fully does.
- Burning or electric pain: sharp, shooting, or burning discomfort in the teeth, gums, lip, or chin that feels different from ordinary surgical soreness.
- Changed sensation to touch or temperature: light touch, cold, or heat may feel dulled, exaggerated, or simply strange.
- Tongue changes: numbness, tingling, or altered taste on one side of the tongue, which points toward the lingual nerve.
Ordinary surgical soreness usually peaks in the first couple of days and then fades. Our guide to managing pain after dental implants explains what normal recovery discomfort looks like, which can help you tell the difference.
What Raises the Risk of Nerve Injury?
Certain anatomical and surgical factors make nerve injury more likely, and a careful surgeon evaluates each of them before placing an implant.
Location and Available Bone
Implants in the back of the lower jaw carry the most risk because the nerve canal runs right below them. When a tooth has been missing for a long time, the jawbone often shrinks, leaving less height between the top of the bone and the nerve. Less room means less margin for error. Patients with significant bone loss may need grafting or a different treatment plan first.
Planning and Imaging
Two-dimensional X-rays can distort or hide the exact position of the nerve canal. Relying on them alone raises the chance that an implant is longer than the bone can safely hold, and anatomical variations such as a forward loop of the mental nerve are much easier to see on 3D scans.
Surgical Technique
Drill depth, implant angle, and soft tissue handling all matter. Some drills cut slightly deeper than their marked length, and heat or pressure from an implant seated tightly against the canal wall can also irritate a nearby nerve.
How Oral Surgeons Lower the Risk of Nerve Damage
Most implant-related nerve injuries are preventable with thorough planning, which is a core part of our dental implant treatment.
3D CBCT Imaging
Cone beam computed tomography (CBCT) produces a three-dimensional view of your jaw. It lets the surgeon trace the nerve canal, measure the exact bone height and width above it, and spot anatomical variations before choosing an implant. You can learn more about this step in our article on why pre-surgical planning matters for implants.
Safety Margins and Implant Selection
Surgeons plan the implant so it stops short of the nerve canal, commonly leaving a buffer of about 2 mm. When bone height is limited, options may include a shorter or narrower implant, angling the implant, or adding bone before placement. Drill stops and computer-designed surgical guides help keep the drill at the planned depth and angle.
When Bone Height Is Very Limited
Occasionally there is not enough bone above the nerve for a standard implant and grafting is not a good fit. A surgeon may then discuss moving the nerve, called nerve repositioning or lateralization, which carries a higher chance of temporary numbness than routine placement. Our post on when nerve repositioning is necessary for dental implants explains who may need it and how it works.
What to Do if Numbness Does Not Go Away
If numbness, tingling, or unusual pain is still present the day after your surgery, contact your oral surgeon right away rather than waiting to see if it passes. Timing matters. If imaging shows that an implant is pressing on or sitting in the nerve canal, backing it out or removing it within the first day or two may improve the chance of recovery compared with leaving it in place.
Your surgeon will typically map where sensation has changed and take imaging to check the implant’s position. Care may include anti-inflammatory medication, repeat sensation testing, adjusting or removing the implant, or medication for nerve pain. If sensation has not improved after a few months, referral for nerve repair may be discussed, since some injuries respond better to earlier repair.
Recovery Outlook for Implant-Related Nerve Injury
The outlook depends on how the nerve was affected. Mild injuries caused by swelling, pressure, or stretching often improve over several weeks to a few months as the nerve heals. As feeling returns, many people first notice tingling, which is often a hopeful sign.
More significant injuries may take many months, and in some cases a year or longer, to reach their final level of recovery. Some patients regain full sensation, while others are left with a smaller area of reduced feeling that they adapt to over time. A minority have lasting numbness or ongoing nerve pain. Early recognition and prompt follow-up give you the best chance at a good result.
Your health and well-being should be the priority. If you have concerns before your procedure, ask your surgeon to show you where the nerve sits on your scan and how the implant is planned around it.

Frequently Asked Questions About Dental Implants and Nerve Damage
How long is numbness normal after dental implant surgery?
Numbness from local anesthetic usually wears off within a few hours, though it can last somewhat longer with certain anesthetics. If your lip, chin, gums, or tongue are still numb the next day, or numbness returns after it had worn off, contact your oral surgeon so they can check whether a nerve may be involved.
Can nerve damage from a dental implant heal on its own?
In many cases, yes. Mild injuries caused by swelling, pressure, or stretching often improve over weeks to months. Healing tends to be more likely when the problem is caught early and any pressure on the nerve is relieved. Some injuries are permanent, so prompt evaluation matters.
Will removing the implant fix the nerve damage?
If imaging shows the implant is pressing on or sitting in the nerve canal, backing it out or removing it soon after surgery may improve the odds of recovery. Removal does not guarantee that sensation returns, and the benefit appears greatest within the first day or two.
Can upper jaw implants cause nerve damage?
It is possible but much less common than in the lower jaw. The main concern in the back of the upper jaw is usually the sinus. Careful 3D planning helps avoid the smaller nerves in the palate and below the eye.
How do oral surgeons avoid nerves when placing implants?
Surgeons use 3D CBCT scans to locate the nerve and measure the bone above it, then choose an implant length that leaves a safety buffer, often around 2 mm. Drill stops, surgical guides, shorter implants, and bone grafting may also be used when bone height is limited.
