Yes, wisdom teeth, also known as third molars, absolutely have nerves. Just like any other tooth, they possess a complex network of nerves that provide sensation and allow you to feel things like temperature, pressure, and pain. Ignoring the nerve supply of wisdom teeth can lead to significant complications during extraction or if problems arise with the teeth themselves. This article will delve into the specifics of the nerve supply, addressing common questions surrounding this often-overlooked aspect of dental health.
What Kind of Nerves Are in Wisdom Teeth?
The nerves in wisdom teeth originate primarily from the inferior alveolar nerve, a branch of the mandibular nerve (the larger nerve that serves the lower jaw). This nerve provides sensation to the lower teeth, including the wisdom teeth. The specific nerve branches supplying each wisdom tooth vary slightly depending on individual anatomy, but the inferior alveolar nerve is the key player.
Furthermore, the lingual nerve and the buccal nerve also contribute to the sensory innervation of the wisdom teeth. The lingual nerve provides sensation to the tongue side (lingual aspect) of the tooth, while the buccal nerve innervates the cheek side (buccal aspect).
How Do Wisdom Teeth Nerves Affect Extraction?
The presence and proximity of these nerves are crucial considerations during wisdom teeth extractions. The inferior alveolar nerve, in particular, runs very close to the roots of the lower wisdom teeth. During extraction, there's a risk of damaging this nerve, leading to temporary or, in rare cases, permanent paresthesia. This is a numbness or tingling sensation in the lower lip, chin, and sometimes tongue.
The complexity of the extraction process is significantly influenced by the tooth's relationship to the nerve. Impacted wisdom teeth (those that haven't fully erupted or are trapped below the gum line) often present a greater challenge because of their proximity to the nerve and the need for more extensive surgical removal.
Can Wisdom Teeth Nerve Damage Be Permanent?
While nerve damage during wisdom tooth extraction is relatively uncommon, it’s a possibility. The vast majority of cases of paresthesia resolve themselves within a few weeks or months as the nerve heals. However, in a small percentage of cases, the damage can be permanent. The risk of permanent nerve damage is higher with more complex extractions, such as those involving impacted teeth or those requiring bone removal.
The skill and experience of the oral surgeon are critical in minimizing this risk. A skilled surgeon will carefully assess the tooth's relationship to the nerve before the procedure and utilize techniques designed to protect the nerve during the extraction process.
Why Does It Hurt When My Wisdom Teeth Are Coming In?
The pain associated with erupting wisdom teeth is directly related to the pressure and inflammation affecting the surrounding tissues and nerves. As the tooth pushes through the gum and bone, it can irritate the nerves, leading to pain, discomfort, and pressure. This pain is often exacerbated by infection or impaction.
What Happens If I Don’t Get My Wisdom Teeth Removed?
Leaving wisdom teeth in place can lead to various problems, including:
- Impaction: The tooth may become impacted, meaning it's unable to fully erupt through the gum line. This can create a breeding ground for bacteria and lead to infections.
- Infection: Impacted wisdom teeth are prone to pericoronitis, an infection of the gum tissue surrounding the partially erupted tooth.
- Damage to Adjacent Teeth: The pressure from an impacted wisdom tooth can cause damage to the nearby second molar.
- Cysts and Tumors: In rare cases, cysts or tumors can develop around an impacted wisdom tooth.
The decision to remove wisdom teeth is a personal one, often based on a comprehensive evaluation by a dentist or oral surgeon. The potential risks and benefits of extraction should be carefully weighed considering individual circumstances and the specific condition of the wisdom teeth.
