What Causes Tooth Nerve Pain and Damage?

Experiencing tooth nerve pain or other troubling pulpitis symptoms? When it comes to the health and survival of your teeth, don’t ignore the early warning signs and symptoms. If not treated promptly, tooth nerve damage can progress from reversible pulpitis to irreversible pulpitis, which is typically associated with excruciating pain from inflamed/dying pulp tissue inside the tooth. Pulpitis accounts for 15-20% of dental emergencies and is most commonly found in adults aged 30 to 50 due to deep decay or tooth trauma. Thankfully, irreversible pulpitis is 95% treatable with root canal treatment to preserve your natural tooth. If damage is too severe or treatment has been delayed, tooth extraction may be necessary. Contact our expert dental team at Great Lakes Family Dental Group for immediate evaluation to avoid severe pain and active tissue destruction.

What Is Tooth Nerve Damage?

What is tooth nerve damage? Damage to the tooth nerve definition can be explained as injury, inflammation, or death of the pulp tissue inside the tooth. The dental pulp is the innermost layer of the tooth, which contains nerves and blood vessels. In cases of reversible pulpitis, the dental pulp may heal if damage is minor and treated early. As bacteria accumulate and infection persists without treatment, reversible pulpitis progresses to irreversible pulpitis and pulp death (pulp necrosis). Patients with irreversible pulpitis often experience severe, lingering pain, requiring root canal therapy or tooth extraction, depending on the extent of damage/infection. The good news is that most cases are treatable with professional intervention before dangerous abscess formation and systemic infection.

Common Causes Of Tooth Nerve Damage

There are several possible causes of tooth nerve damage. Understanding these causes and risk factors can help you prevent permanent tooth damage and serious health consequences. The primary causes of pulpitis include:

Deep tooth decay/cavities: An astonishing 60% of cases of tooth nerve damage are due to deep decay reaching the pulp. Surprisingly, untreated cavities are the most preventable cause.
Dental trauma/fractures: Accidents, sports injuries, or impact to the face can lead to tooth inflammation and nerve damage. Dental trauma can cause cracked or fractured teeth, allowing bacteria to enter the dental pulp and promote damage.
Repeated dental procedures: Teeth with extensive decay or damage often require large dental fillings or crowns to protect teeth from further damage. When decay is close to the pulp, temporary nerve inflammation may occur.
Bruxism/grinding: Chronic teeth grinding or clenching (bruxism) can create excessive pressure on teeth and trigger nerve inflammation. The wear and tear also leads to tooth enamel loss over time, which exposes inner tooth layers that are more sensitive and prone to decay/damage.
Thermal/chemical irritation: Extreme hot or cold stimuli can irritate the dental pulp and result in permanent damage when chronically exposed. Chemical stimuli such as acidic foods and beverages, teeth whitening products, and stomach acids can also trigger nerve pain and irreversible tooth damage.

Types Of Tooth Nerve Damage

There are two main types of tooth nerve damage: reversible vs irreversible pulpitis. Reversible pulpitis is typically caused by mild inflammation of the dental pulp due to minor tooth damage or an external stimulus, such as pressure from teeth grinding, hot or cold air, foods, or beverages. Individuals may experience a sharp pain temporarily, which dissipates once the stimulus is removed. If treated early, the inflamed dental pulp can be fully healed. Teeth affected by reversible pulpitis have a normal or immediate response to dental thermal testing and respond without significant pain or sensitivity to percussion tests.

Irreversible pulpitis involves severely inflamed dental pulp, which can lead to life-threatening infection if not treated urgently. Once the nerve damage has reached this stage, the pulp cannot heal and will require permanent dental treatment like root canal therapy or tooth extraction to eliminate the infection. Irreversible pulpitis is commonly a consequence of delaying treatment of reversible pulpitis, leading to the accumulation of bacteria and spread of infection. Symptoms may progress from spontaneous throbbing to no symptoms over time as the tooth’s pulp dies (pulp necrosis). When dental thermal and percussion tests are performed, teeth with irreversible pulpitis may present with severe lingering pain or no response.

Symptoms And Warning Signs Of Tooth Nerve Damage

Tooth nerve damage symptoms and signs can range from mild sensitivity to emergency symptoms. The severity of pulpitis pain is frequently one of the main indicators of whether tooth nerve damage is reversible or irreversible. For instance, spontaneous pain and night pain is common with irreversible pulpitis and indicate the need for immediate dental treatment. Early treatment is crucial for preventing dangerous health consequences like abscess formation and the spread of infection. The progression of tooth nerve damage may involve the following signs and symptoms:

Sharp pain from hot/cold/sweet foods or beverages
Minor/superficial enamel wear or damage
Prolonged pain after the stimulus is gone
Spontaneous throbbing pain
Night pain waking from sleep
Facial/gum swelling
Abscess formation, pus drainage
Tooth discoloration (gray tooth)

Why Tooth Nerve Damage Requires Prompt Treatment?

Sadly, tooth nerve damage cannot heal on its own without professional treatment. Tooth nerve damage complications are serious and should be addressed immediately by a medical or dental professional. Common untreated pulpitis risks include tooth loss, jawbone and tissue loss, abscess formation, and systemic infection. There is typically only a narrow 24 to 72-hour window once severe symptoms are present for treatment to be managed with a pain-free root canal, versus having to have an emergency tooth extraction.

What To Do Immediately For Tooth Nerve Pain?

Pulpitis emergency care must be managed professionally. After immediately contacting your dentist for an emergency appointment, there are several steps you can follow for temporary tooth nerve pain relief while you wait. If approved by your dentist or medical professional, consider taking OTC pain medications like 600mg of ibuprofen every 6 hours. They may also recommend taking acetaminophen (Tylenol) alongside ibuprofen for stronger relief. Apply a cold compress to the affected area in 15 to 20-minute intervals to help temporarily reduce swelling and numb the area. Warm salt water rinses and OTC topical numbing gels may also be helpful in briefly reducing symptoms. Switch to a soft foods diet, taking care to also avoid hot, cold, sweet, and acidic foods and beverages. Most importantly, do not delay seeking professional care, as this leads to larger infections and the need for more complex and costly treatments.

How Dentists Diagnose Tooth Nerve Damage?

Diagnosing tooth nerve damage typically involves a thorough examination, clinical tests (i.e. thermal, electric pulp, and percussion testing), and the use of advanced diagnostic tools like dental X-rays and 3D imaging. Your dentist will clinically look for signs of tooth damage, infection, or decay. Pulp vitality testing is also performed to aid in diagnosis and determine whether the nerve is alive or dead. Your dentist may apply pressure or hot, cold, or electric stimuli to teeth and monitor the tooth’s response. An unhealthy or damaged nerve will respond abnormally, which typically manifests as a weakened or delayed response, or no response at all.

A diagnosis of reversible pulpitis involves mild inflammation and dental pulp that is still viable and can heal if the underlying irritant is removed promptly. Irreversible pulpitis refers to severe tooth damage or infection of the dental pulp resulting in pulp death (necrosis). Radiographic imaging is crucial for aiding in accurate diagnosis and protecting patients from overtreatment by detecting issues that cannot solely be seen visually, such as periapical radiolucency, bone loss, and dental abscesses.

Tooth Nerve Damage Treatment Options

Tooth nerve damage treatment primarily depends on the severity of the damage. Conservative treatments tailored to resolving the underlying cause of nerve irritation may be recommended for patients with mild tooth sensitivity or reversible pulpitis. For instance, if nerve irritation is triggered by gum recession or tooth sensitivity without the presence of decay, non-invasive treatments like professional desensitizing toothpaste or fluoride gels/varnishes may be applied by your dentist to help reduce sensitivity and promote healing. If teeth grinding is the underlying cause of nerve irritation, a custom night guard made by your dentist may be recommended. If nerve irritation is caused by damage or decay that has not yet reached the dental pulp, a dental filling is typically performed.

A root canal for pulpitis is considered the gold standard for saving a natural tooth when nerve damage is irreversible. Your dentist will remove the infected nerve tissue and pulp, clean the tooth’s root canal, and seal it to prevent further infection and damage. A dental crown may be placed after a root canal to provide structural support to the tooth and prevent bacteria from causing reinfection. If the tooth is extensively damaged or signs and symptoms of infection are severe, tooth extraction with future replacement will be necessary. Your dentist will discuss tooth replacement options like dental bridges and implants to preserve your smile.

Tooth Nerve Damage In Children Vs Adults

There are important differences to note regarding children vs adult pulpitis treatment. Treatment for pediatric tooth nerve damage is often dictated by the extent of trauma and the developmental stage of the tooth (i.e., primary/baby, immature permanent, or mature permanent tooth).

In contrast to adult teeth, baby teeth have a larger dental pulp and thinner enamel, which makes them more susceptible to tooth decay and nerve damage. In addition, severe trauma to a baby tooth can affect the health of the developing permanent tooth if not treated promptly. For children with damaged baby teeth, a partial root canal (pulpotomy) is typically performed to temporarily save the tooth and preserve spacing for the developing adult tooth. Your dentist will continue to monitor the health of the treated baby tooth and its permanent successor. This involves removing the infected pulp from within the tooth’s crown, while leaving the roots intact.

If a child’s permanent tooth becomes damaged while the roots have not completely developed, immature apex treatment may be indicated, such as apexogenesis or apexification. Apexogenesis is used when the tooth is still alive, and involves removing only the infected pulp from the tooth’s crown and placing a biocompatible medicine to allow the tooth’s root to continue developing naturally. Apexification is performed when the tooth’s pulp is severely damaged or dead, and involves removing the infected pulp from the tooth’s crown and root. Since the root tip is open due to incomplete growth, a biocompatible barrier is placed to help seal the root before a traditional root canal procedure is performed. Growing children tend to heal more quickly after dental procedures than adults, making procedures usually simpler with fewer complications.

The main goals of adult treatments are to eliminate infection and save natural teeth whenever possible. Since permanent teeth in adults are fully mature, traditional root canal therapy is usually indicated for teeth with mild to moderate tooth nerve damage. This involves removing the infected nerve and pulp tissue from the tooth’s crown and root and sealing it with a biocompatible material to prevent further damage.

Preventing Tooth Nerve Damage Progression

There are many key strategies you can implement to prevent tooth nerve damage. Pulpitis prevention requires diligent oral hygiene to stop bacterial decay and inflammation from causing infection in the dental pulp. Prioritize gently brushing twice a day for two minutes each session with a fluoride toothpaste and flossing daily to prevent harmful bacteria accumulation. Fluoride protection is essential for preventing decay by inhibiting bacterial growth, strengthening tooth enamel, and reversing early tooth decay. Also, be sure to limit foods that promote tooth decay and nerve damage, including sugary and acidic foods and beverages.

Maintain routine dental checkups and professional cleanings at least at the frequency recommended by your dentist, at a minimum every six months. It is important to address dental issues like cavities early, before causing permanent damage to the tooth and reach the dental pulp. Protect your teeth against trauma by wearing appropriate protective equipment like mouthguards, face shields, and helmets when participating in contact sports. If you notice habits like teeth grinding, speak with your dentist about professional custom night guards to prevent tooth enamel wear, which can expose the inner layers of your teeth over time.

When To Seek Emergency Care For Tooth Nerve Damage?

Untreated pulpitis can quickly trigger pulpitis abscess warning signs and symptoms that indicate a life-threatening tooth nerve emergency. If you experience these red flags, seek immediate emergency dental care or go directly to the ER after hours to avoid serious systemic health complications:

Severe tooth pain
Unrelenting pain that suddenly stops
Swelling spreading to the face, jaws, or neck
Fever or chills
Pimple on gums/pus drainage (dental abscess)
Persistent foul breath/taste
Tooth discoloration (dark yellow, gray, brown, or black)
Loose tooth
Difficulty opening your mouth, chewing, swallowing, speaking, or breathing
Rapid heart rate
Mental confusion

Frequently Asked Questions

Can tooth nerve damage heal on its own?

In general, tooth nerve damage cannot heal on its own and requires professional treatment to resolve. Mild nerve inflammation, known as reversible pulpitis, may occur from irritants and heal when detected and treated early with professional help. Irreversible pulpitis is caused by severe damage or inflammation, which often requires more complex treatment (i.e. root canal therapy, crowns, tooth extraction) to prevent the spread of infection and severe health issues.

How long does pulpitis pain last before a root canal?

Pain from irreversible pulpitis may last for several days to weeks before a root canal. Pain is usually severe, spontaneous, and lingering, even when no external triggers are present (i.e. hot, cold, sweet, or acidic stimuli). Over time, as the nerves within the tooth die, pain may temporarily go away. If not treated urgently, a severe dental abscess may form, and infection can spread and cause life-threatening health problems. If you experience pulpitis pain, contact your dentist right away for evaluation and treatment.

Is root canal the only treatment for nerve damage?

There are various treatment options for nerve damage depending on the cause and severity. If nerves are not permanently damaged (reversible pulpitis), treatment focuses on eliminating the irritant causing the issues. Common treatments for reversible pulpitis include removing minor tooth decay and placing dental fillings, replacing faulty dental restorations, or applying desensitizing agents (i.e., fluoride). If nerve damage is permanent (irreversible pulpitis), root canal therapy or tooth extraction may be recommended.

Will my tooth darken after nerve death?

Internal tooth discoloration is a common consequence of nerve death. Damaged nerve tissue and blood vessels cause the tooth to turn yellow, grey, or darker in color gradually over time. Common treatments for nerve death (pulp necrosis) include root canal therapy, internal bleaching, veneers, and crowns.

Can tooth nerve pain come and go?

Yes, tooth nerve pain commonly comes and goes intermittently. Inflammation is often triggered by heat, cold, sweet, or acidic stimuli, and may go away once stimuli are removed. Although you may experience temporary relief from symptoms, it’s important to promptly seek dental evaluation to treat the underlying problem. Tooth nerve pain may eventually disappear completely, which could be an indication of nerve death and serious infection.

Does tooth nerve damage always require extraction?

Fortunately, tooth nerve damage does not always require extraction. Your dentist will prioritize saving your natural teeth when possible. Treatments like dental fillings, crowns, and root canal therapy are commonly recommended for tooth nerve damage. If tooth damage or infection is too severe and beyond the ability to repair, tooth extraction with dental restorative replacement will be recommended as the last resort.

How do dentists test if the tooth nerve is dead?

During your examination, your dentist will perform a series of tests to determine if a tooth nerve is dead (pulp necrosis). They may evaluate your tooth’s response to cold, heat, or pressure stimuli. They will also use other diagnostic tools like dental X-rays to evaluate the health of your jawbone and tooth’s inner layers and roots.

Can children get root canals for nerve damage?

Like adults, children can get root canals for nerve damage. Root canals may be performed on a child’s baby tooth or adult tooth that has been damaged or infected. For baby teeth, a dental pulpotomy may be performed, which involves removing the damaged pulp from the tooth’s crown while keeping the healthy pulp within the roots intact. A stainless steel crown is typically placed on the tooth after a pulpotomy for protection, which will eventually exfoliate naturally with the baby tooth.

Will antibiotics cure a tooth nerve infection?

Antibiotics alone cannot cure a tooth nerve infection. Prompt professional evaluation and treatment are key to preventing the spread of bacteria and saving your natural tooth. Although antibiotics can help temporarily manage bacteria, additional treatments are typically needed in combination with antibiotics to fully eliminate the infection.

What happens if pulpitis goes untreated?

Untreated pulpitis leads to serious health issues. Early stages of pulpitis may be reversible when detected and treated early. Over time, the inflammation worsens and leads to irreversible pulpitis, causing severe, lingering, and spontaneous pain. Eventually, the tooth’s nerves and blood vessels die (pulp necrosis), which can lead to numerous issues, including a life-threatening dental abscess.
