Tooth Pain That Won't Go Away: What It Means and What to Do

Constant or throbbing tooth pain, especially pain that wakes you at night, means the tooth needs professional dental attention — it won't resolve on its own. The most common causes are a deep cavity reaching the nerve, a cracked tooth, or a dental abscess. Antibiotics can slow a spreading infection but cannot replace dental treatment. Seek emergency care now for facial swelling, fever, or difficulty swallowing.

Why does tooth pain persist — what is likely happening?

A tooth that aches briefly when cold touches it, then settles quickly, may have a minor issue. But pain that lingers for more than a few seconds after a stimulus — or pain present without any trigger — usually means the nerve inside the tooth (the pulp) is inflamed or dying 1.

This is typically caused by: - Deep tooth decay that has reached the pulp chamber - A crack or fracture extending toward the root - A failing filling or crown - A dental abscess — a pocket of infection at the root tip or between the tooth and gum 1

Once the nerve is involved, the tooth will not improve without treatment. The question is not whether to see a dentist — it is how soon.

How can you manage pain while waiting for a dental appointment?

These are bridges, not treatments. They will not fix what is happening inside the tooth.

  • OTC NSAIDs (ibuprofen, naproxen): Anti-inflammatories address both pain and the inflammatory component of dental pain. Taking them as directed with food is generally more effective than acetaminophen alone for dental pain. Do not exceed recommended doses; discuss with a clinician if you have kidney disease, stomach ulcers, or take blood thinners.
  • Acetaminophen: A reasonable option if NSAIDs are not safe for you.
  • Topical benzocaine gels (Orajel): Available OTC; can temporarily numb the area.
  • Cold compress: Ice pack on the outside of the cheek in 15-minute intervals can dull pain. Avoid heat — it can intensify an abscess.
  • Avoid temperature extremes: Hot or cold food and drinks often make dental nerve pain worse.
  • Clove oil (eugenol): A traditional topical remedy with some short-term numbing properties.

The American Dental Association (ADA) recommends prioritizing dental treatment such as pulpotomy, pulpectomy, or root canal over antibiotics for most localized dental infections 3.

What happens at the dentist?

A dentist will examine the tooth, take X-rays to see what is happening at the root and bone level, and determine whether the tooth can be saved.

  • Root canal: Removing the infected nerve tissue, sealing the canal, and typically crowning the tooth afterward. Modern root canal procedures are done under local anesthesia and typically feel no worse than getting a filling — and the relief from the pre-existing infection pain is often dramatic.
  • Extraction: Less expensive upfront but requires planning for tooth replacement later.
  • Antibiotics: If an abscess is present, a dentist may prescribe antibiotics to control the spread of infection. However, antibiotics alone will not resolve an abscess — the tooth itself must be treated 3. Untreated infections can spread to the jaw, neck, or beyond — the mortality rate can increase significantly if a descending neck infection develops 2.

If cost is a significant barrier, ask about payment plans, dental schools, community health centers, or dental discount plans.

Where to get help if cost or access is a barrier

  • Dental schools: supervised treatment at significantly reduced rates; complex cases handled routinely
  • FQHCs (Federally Qualified Health Centers): sliding-scale fees based on income
  • 211: call or text to be connected with local low-cost dental resources
  • Dental discount plans: not insurance, but annual membership fees in exchange for reduced rates at participating providers
  • Urgent care or ER: can provide antibiotics and pain management as a bridge if you cannot access a dentist immediately — they cannot perform the dental procedure, but they can treat a spreading infection

Common questions

Can a tooth abscess go away on its own?

No. A dental abscess is a bacterial infection that requires treatment — either draining through root canal therapy or extraction, often with antibiotics to control spread. Left untreated, the infection can spread to the jaw, neck, or beyond and become life-threatening.

How do I know if I need a root canal or if the tooth should just be pulled?

That depends on the extent of damage, the tooth's position, and your long-term priorities. Saving the natural tooth is generally preferred when possible, but it requires a clinical exam and X-rays to assess. Your dentist can give you estimates for both options.

Can I take antibiotics instead of going to the dentist?

Antibiotics can slow a spreading infection and help you feel better temporarily, but they do not remove the source of the infection inside the tooth. Without treating the tooth itself, the infection will return. Antibiotics are a bridge, not a solution.

When tooth pain becomes a medical emergency

  • —Swelling in the face, jaw, cheek, or neck — especially spreading rapidly
  • —Difficulty swallowing, breathing, or opening your mouth fully
  • —Fever with tooth pain
  • —Pus or a bad taste draining from the gum near the tooth
  • —Severe throbbing pain worsening and not controlled by OTC pain relievers
  • —Facial redness and warmth spreading beyond the jaw

Swelling in the face, jaw, or neck with difficulty swallowing or breathing is a dental infection that can become life-threatening within hours. Call 911 or go to the nearest ER immediately. A fever with facial swelling also warrants the ER.
