What to Do When the Nerves in Your Teeth Hurt?

Tooth nerve pain, also known as a toothache, signals irritation or inflammation of the delicate nerves within a tooth. This discomfort can range from a dull ache to a sharp, intense jolt, significantly impacting daily activities. Understanding this pain and knowing when to seek help can guide you toward relief. Though temporary measures can alleviate immediate discomfort, professional dental intervention is typically necessary to address the underlying cause.

Immediate Steps for Pain Relief

Several at-home remedies can provide temporary relief until you can see a dentist. Over-the-counter pain relievers, such as ibuprofen or naproxen, can help reduce both pain and inflammation. Acetaminophen is another effective option for pain relief, especially if anti-inflammatory effects are not needed or other medications are contraindicated.

Applying a cold compress to the outside of your cheek can help numb the area and reduce swelling by constricting blood vessels. Rinsing with warm salt water can also soothe irritated tissues and act as a mild antiseptic. Topical anesthetic gels containing benzocaine can also be applied directly to the sore area for temporary numbing.

Avoid foods and drinks that might worsen the pain, such as very hot, cold, sweet, or acidic items. Avoiding chewing on the painful side and keeping your head elevated, especially when lying down, can also help minimize discomfort. These measures are intended for short-term relief and do not address the root cause of the pain.

Common Causes of Tooth Nerve Pain

Tooth nerve pain often stems from underlying issues affecting the tooth’s internal structures. The most frequent cause is dental decay, commonly known as cavities. Bacteria produce acids that erode enamel, allowing decay to reach the pulp, which houses the nerves and blood vessels, leading to significant pain.

Gum disease (periodontitis) can also contribute to nerve pain. This condition causes gum recession, exposing sensitive tooth roots where nerve endings are more vulnerable to external stimuli. Cracked or chipped teeth can also expose inner layers, allowing temperature changes or bacteria to irritate the nerve.

Worn enamel, often due to aggressive brushing, acidic foods, or teeth grinding (bruxism), diminishes the tooth’s protective outer layer. This exposes the underlying dentin, which contains microscopic tubules leading to the nerve, resulting in increased sensitivity. Dental abscesses, pus-filled pockets caused by bacterial infections, can also exert pressure on nerves, causing intense, throbbing pain.

When to Seek Professional Dental Care

Seek professional dental care when tooth nerve pain persists or worsens, as it often indicates a problem home remedies cannot resolve. Contact a dentist if your toothache lasts longer than one or two days, does not improve with over-the-counter pain medication, or interferes with eating or sleeping.

Specific symptoms warranting a prompt dental visit include swelling in your face or jaw, pain when opening your mouth wide, or a fever with the toothache. Visible signs of decay, a chipped or broken tooth, or persistent sensitivity to hot or cold temperatures also indicate a need for professional evaluation. Ignoring these signs can lead to more complex problems, such as the spread of infection.

Dental Treatments for Nerve Pain

When tooth nerve pain requires professional intervention, dentists have various treatments to alleviate discomfort and address the cause. For cavities not reaching the deepest part of the tooth, a dental filling is often sufficient. The dentist removes the decayed portion and fills the space with a restorative material, protecting the nerve.

If decay or infection has reached the pulp, root canal therapy is typically performed. This involves removing the inflamed or infected pulp tissue, thoroughly cleaning and disinfecting the tooth, and then sealing it to prevent reinfection. Afterward, a dental crown is often placed over the treated tooth to restore its strength and protect it.

For cracked or weakened teeth, a dental crown can also provide protection and reduce nerve irritation by encasing the tooth. For gum disease leading to exposed roots, specialized periodontal treatments can help manage the infection and reduce sensitivity. If a tooth is severely damaged or infected beyond repair, extraction may be the only option to remove the pain source and prevent further complications.

Preventing Future Nerve Pain

Preventing future tooth nerve pain involves consistent oral hygiene and regular dental check-ups. Brushing twice a day with fluoride toothpaste helps strengthen enamel and protect against decay. Flossing daily removes food particles and plaque, preventing gum disease and cavities.

Routine dental examinations and professional cleanings allow dentists to identify and address potential issues, such as small cavities or gum inflammation, before they cause nerve pain. Using toothpaste designed for sensitive teeth, which often contain ingredients like potassium nitrate or stannous fluoride, can also help reduce sensitivity. If teeth grinding (bruxism) is a concern, wearing a night guard can protect teeth from excessive wear and pressure, safeguarding the nerves.
