What causes paresthesia in dental?
It involves a situation where tissues or structures in or around the mouth (lip, tongue, facial skin, mouth lining, etc…) experience prolonged or possibly permanently altered sensation as a result of nerve trauma. In most cases, the trauma has been caused by an event that has bruised, stretched or crushed the nerve.
What is dental paresthesia?
Dental paresthesia is loss of sensation caused by maxillary or mandibular anesthetic administration before dental treatment.
What nerve do they numb for dental work?
Also called regional anesthesia or a nerve block because many blocks numb the alveolar nerve. Blocking sensation in the alveolar nerve will numb the teeth, jaw, or lips. But there are many different areas where a dentist or oral surgeon can use anesthesia for a dental procedure.
How common is dental paresthesia?
IAN paresthesia may occur after various dental procedures such as simple anesthetic injections, surgical procedures, and endodontic treatment, and is reported to range from 0.35% to 8.4%. The altered sensation usually follows immediately after the procedure, and reports of late onset of nerve involvement are rare.
What local anesthetics cause paresthesia?
number of reported cases involving articaine increased markedly, and articaine became the local anesthetic most reported to be associated with paresthesia across the entire study period.
What is inferior alveolar nerve damage?
There is a range of common inferior alveolar nerve damage symptoms, regardless of how the IAN is damaged. A damaged IAN will reveal itself through pain or abnormal sensations in the chin, lower teeth, lower jaw, and lower lips. Nerve damage may result in speech difficulties and/or affect chewing.
How does the trigeminal nerve get damaged?
Trauma and injuries can affect the trigeminal nerves. Accidents, tumors and damage from dental procedures or facial surgery can bruise or cut the nerves. A trigeminal nerve injury may affect a small area, like part of your gum, or a large area, like one side of your face.
How common is lingual nerve damage?
Lingual nerve injury is an uncommon but important complication in the removal of the mandibular third molar. Renton et al. reported that the incidence of lingual nerve injury was estimated to vary from 0.02 to 2% of the patients undergoing third molar surgery [2].
Can anesthesia cause paresthesia?
Paresthesia is an unfortunate yet sometimes unavoidable complication associated with local anesthesia administration. As a result, paresthesia is a common cause of legal actions against dental professionals.
What is the lingual nerve?
The lingual nerve is one of the sensory branches of the mandibular division of the trigeminal nerve. [5] It contains general somatic afferent nerve fibers and, after chorda tympani joins it, also carries general visceral efferent nerve fibers and special visceral afferent fibers.
What happens when the dentist hits a nerve?
Some of the signs and symptoms of tooth nerve damage after receiving dental treatment include: Numbness or lack of feeling in the tongue, gums, cheeks, jaw or face. A tingling or pulling sensation in these areas. Pain or a burning feeling in these areas.

Dental paresthesia is a possible postoperative complication associated with the removal of teeth (most frequently lower wisdom teeth), or in some cases receiving a dental injection.
What is paresthesia after tooth extraction?
Most cases of paresthesia following an extraction occur in conjunction with the removal of lower 3rd molars (wisdom teeth) and to a lesser extent lower 2nd molars (the next tooth forward). Tooth roots lying in close proximity to the Inferior Alevolar nerve. A person’s risk generally correlates ...
Why do I get paresthesia after dental injection?
Some cases of paresthesia (especially those caused by dental injection) may be due to pressure/compression directed on the nerve by local swelling. If so, an anti-inflammatory approach would assist in controlling this etiology.
What is the term for nerve damage as a complication of wisdom tooth extraction?
Dental paresthesia: Nerve damage as a complication of wisdom tooth extraction or dental injection. Dental paresthesia: Nerve damage as a complication of wisdom tooth extraction or dental injection.
How many inferior alveolar mandibular blocks are there?
It’s been estimated that roughly 1 out of 27,000 Inferior Alveolar Mandibular blocks (the type of dental injection used to numb up lower back teeth, and the one most associated with this complication) will result in paresthesia.
How does tooth orientation affect paresthesia?
A tooth’s precise orientation in the jawbone plays a role in paresthesia risk in two ways: 1) Tooth-nerve proximity. 2) It can greatly affect the surgical difficulty (and thus level of trauma) associated with removing the tooth.
How long does paresthesia last?
In most cases, a patient’s paresthesia will resolve on its own over time, with the amount of time ranging from just a few days, to several months, to over a year. In some cases a person’s sensory loss, complete or partial, is permanent.
How often do nerves damage after dental injections?
I’ve seen estimates range from 1 per 100,000 injections up to 1 per 600,000 injections. No matter what the exact frequency is, it is an extremely rare event. In almost every case it is associated with a mandibular block injection (used for bottom teeth to numb the entire bottom jaw on one side). As a comparison your odds of being struck and killed by lightning are about 1 in 70,000.
Why do wisdom teeth get removed?
The reason for this is that lower wisdom teeth are in close proximity to the inferior alveolar nerve as well as the lingual nerve. The trauma from the extraction can damage these nerves. In most cases the damage is temporary with about 90% resolving in about 8 weeks. It’s thought that somewhere between 2-4% of cases of nerve damage end up being permanent.
What is the rarest dental problem?

Can dental implants cause nerve damage?
Dental implants are placed directly into the bone. If the implant comes into close contact with any branches of the nerves, it can cause damage to it. Most of these cases are preventable with proper planning beforehand. It isn’t unusual for oral surgeons and dentists to take a CT scan of the area beforehand to check for the exact location of the nerves so that they can avoid them.
Can nerve damage occur after dental surgery?
Nerve damage can also occur after other significant types of dental surgery including orthognathic surgery (breaking your jaw and resetting it for orthodontic reasons), periodontal flap surgery, and cyst or tumor removal. If you’re undergoing significant dental or oral surgery, discuss with your surgeon the risks prior to starting so that you aren’t surprised afterwards.
How long after dental surgery can you have pain?
