Why Is Half of My Tongue Numb After Wisdom Tooth Extraction?

Half of my tongue is numb after having my wisdom teeth removed?

After having my wisdom teeth removed on January 26, the wound hasn't had any major issues, but half of my tongue has been numb and tingling, and I have lost my sense of taste.
I would like to know what could be the cause of this.
Should I see a doctor again, or is this normal and will it heal on its own?

In the above situation, it is possible that the wisdom tooth was positioned deeper, and during the extraction process, surrounding alveolar bone had to be removed, which may have inadvertently affected the nerve.
If the damage is not severe, it is generally expected to gradually recover function over a few months.
It is advisable to consult a dentist for further follow-up examinations.

More Info

After having your wisdom teeth extracted, experiencing numbness or a tingling sensation on one side of your tongue can be concerning. This symptom is not uncommon and can be attributed to several factors related to the procedure.

Firstly, during the extraction of wisdom teeth, especially if they are impacted or located near nerves, there is a risk of nerve injury. The lingual nerve, which is responsible for sensation in the tongue, can be affected during the extraction process. If this nerve is bruised or slightly damaged, it can lead to temporary numbness or altered sensation, such as a tingling feeling or loss of taste on the affected side of the tongue. This condition is known as "neuropraxia," which is a temporary nerve injury that often resolves on its own over time.

The numbness you are experiencing may also be due to the anesthesia used during the procedure. Local anesthetics can cause temporary numbness in the areas they are administered, including the tongue. As the anesthesia wears off, you should gradually regain normal sensation. However, if the numbness persists beyond a few days or worsens, it is advisable to consult your dentist or oral surgeon for further evaluation.

In most cases, if the numbness is due to nerve irritation or temporary damage, it should improve within a few weeks to a few months. However, it is essential to monitor your symptoms. If you notice any signs of infection, such as increased swelling, redness, or discharge from the extraction site, or if the numbness does not improve, you should definitely return to your dentist for a follow-up appointment.

Additionally, if you are experiencing significant pain, changes in your ability to taste, or any other unusual symptoms, it is crucial to seek professional advice. Your dentist may perform an examination, possibly including imaging studies, to assess the situation and determine if any further treatment is necessary.

In summary, while some numbness or tingling in the tongue after wisdom tooth extraction can be normal and may resolve on its own, it is essential to keep an eye on your symptoms. If you have any concerns or if the symptoms persist, do not hesitate to reach out to your healthcare provider for guidance. They can provide reassurance and help ensure that your recovery proceeds smoothly.
