A dentist checks for nerve damage through visual exams, sensitivity tests (hot, cold, pressure), X-rays, and sometimes advanced imaging like CT scans to assess decay, trauma, or infection affecting the nerve, using tools like pulp vitality tests and nerve conduction studies for detailed nerve function evaluation, especially if a tooth's nerve is suspected dead or damaged.
A nerve conduction study measures the passing of electrical signals by placing electrodes at two points on the body. And an MRI, or MRA may produce a 3D image of the nerve detailed enough to identify damage.
Recognizing the Symptoms
This is one of the most common symptoms. Tingling or Pins-and-Needles: An unusual sensation in the affected area. Pain: Can range from a mild ache to a sharp, burning sensation. Sometimes this manifests as phantom tooth pain after an extraction.
EMG and nerve conduction studies are used to help check for many kinds of muscle and nerve disorders. An EMG test helps find out if muscles are responding the right way to nerve signals. Nerve conduction studies help to check for nerve damage or disease.
If you've a toothache but your dentist says nothing is wrong, it could be the surrounding soft and hard tissues that are referring pain to your teeth. Due to their close proximity, your body may be confused and perceive it as a toothache while it is actually something else.
To relieve pregnancy tooth nerve pain, use cold compresses, rinse with warm salt water, and try pregnancy-safe numbing gels or acetaminophen (after checking with your doctor) for temporary relief, but seeing a dentist is crucial for a permanent fix, as dental issues don't resolve on their own and can worsen during pregnancy. Avoid NSAIDs like ibuprofen.
The 3-3-3 rule for toothache is a temporary pain management strategy: take 3 ibuprofen (200mg each) three times a day for 3 days, but 3 hours apart (or every 8 hours), to reduce inflammation and pain until you can see a dentist; it's crucial to consult a doctor first, especially with underlying conditions, as it's not a cure but a short-term fix for inflammation.
Diabetes, chronic alcohol use, certain medications, and autoimmune disorders are common contributors. Additionally, repetitive strain, vitamin deficiencies (particularly B12), and poor circulation can mimic neuropathic pain.
The most common types of tests for peripheral neuropathy (either to confirm the diagnosis or rule out other conditions) include: Blood tests (these can detect many problems, ranging from immune system problems to toxins and poisons, especially metals like mercury or lead). Electromyogram. Nerve ultrasound.
Nerves may be squeezed or pinched by surrounding tissues, which increases pressure on the nerve and may disrupt function. This can lead to muscle weakness, a burning or tingling sensation, numbness or pain.
Surgery. There are several surgical procedures that can be done to treat dental nerve damage. Most of these surgical procedures work by reducing pressure on the pain, causing nerves, or by cutting pain signals that are relayed to the brain. One such procedure is necrolysis, which can be done internally or externally.
Sometimes, dental nerve damage manifests as sharp, shooting pains. These pains can be triggered by hot or cold temperatures, or even by chewing. You might feel a sudden, intense jolt that subsides quickly, but leaves a lingering ache. Other times, the pain is a constant, dull throb that just won't go away.
Root and Pulp Issues: The inside of your tooth contains the pulp, which houses the nerves and blood vessels. X-rays can show if the pulp is damaged or infected, which may require a root canal.
Discomfort is possible, but EMG is usually well tolerated without medication. EMG is extremely safe, including for patients with joint replacements, pacemakers, or those taking blood thinners. Side effects are minimal, usually limited to brief muscle soreness lasting an hour or two after the test.
Nerve tooth pain often feels more intense than other types of dental pain. It can present as a sudden jolt of pain when you bite down, drink something hot or cold, or even when you breathe in cold air. For some people, the pain can come and go. For others, it's constant and difficult to ignore.
Schwann cells can help damaged nerves regenerate and restore function. On average, damaged nerves can grow back at a rate of about 1 inch per month or 1 millimeter per day. Surgery is needed if there is significant scar tissue or a gap between cut nerve ends.
Symptoms of peripheral neuropathy might include: Gradual onset of numbness, prickling, or tingling in your feet or hands. These sensations can spread upward into your legs and arms. Sharp, jabbing, throbbing or burning pain.
To stop nerve pain immediately, topical lidocaine or capsaicin creams/patches can provide quick numbing relief, while prescription options like anti-seizure drugs (gabapentin) or strong painkillers (tramadol) offer faster but not always instant relief; gentle stretches, TENS, and relaxation techniques can also help manage acute flare-ups by blocking pain signals or relaxing muscles.
Conditions that can cause nerve pain include:
Neuropathy is a general term for any damage or dysfunction of the nervous system due to injury or disease. This can cause a variety of symptoms, including pain, tingling, and numbness in the hands and feet. Neuropathic pain, on the other hand, refers specifically to pain or pain conditions caused by neuropathy.
You're likely to start by seeing your health care professional. You may then be referred to a doctor trained in nervous system disorders, also called a neurologist. Here's information to help you get ready for your appointment.
Dealing With an Exposed Nerve? Here's What to Do
Code 1 – Slight bleeding when probed, no calculus or gingival pockets under 3.5mm. Code 2 – Slight bleeding when probed, Calculus or Plaque present and gingival pockets under 3.5mm. Code 3 – Calculus and Plaque present under the gum margin and gingival pockets between 3.5 – 5.5mm.
The golden rule for oral hygiene encompasses a consistent and comprehensive approach to dental care. You can ensure a healthy and beautiful smile by brushing twice daily, flossing daily, using mouthwash, maintaining a nutritious diet, staying hydrated, avoiding tobacco, and visiting your dentist regularly.
