Severe Toothache — Same-Day Assessment

Throbbing or lingering tooth pain needs an exam, not a guess from a web page.

What is happening?

A severe toothache is pain coming from a tooth or the tissue around it. Common sources include decay that has reached the nerve, a crack, an abscess, a lost filling that has exposed dentin, food packed between teeth, or sinus pressure that mimics an upper molar.

While you are on the way for a toothache

  1. Call us

    Tell us the pain started, whether it wakes you, and whether your face is swelling.

  2. Pain relief

    Use ibuprofen and/or acetaminophen as the package directs. Do not place aspirin on the gum — it burns the tissue.

  3. Cold, not heat

    A cold compress on the outside of the cheek, 15 minutes on and 15 off. Do not put heat on the face, and skip very hot or very cold food.

Common causes

Deep decay reaching the nerve (pulpitis) · A cracked tooth · A dental abscess · A failing or lost filling exposing dentin · Food impaction between teeth · Sinus pressure mimicking an upper molar

How we diagnose it

We examine the tooth, test it with cold and biting, and take an x-ray when that will show the nerve, a crack, or an infection. If a flat x-ray cannot explain the pain, we say so and discuss the next image — we do not treat the symptom as if it were the diagnosis.

How we treat it

  • Find the source

    The visit starts by separating a nerve problem, a crack, an abscess, and a sinus mimic. The treatment follows that finding.

  • Relieve the cause

    That may be a filling, a crown, a root canal, drainage, or an extraction if the tooth cannot be kept. You get a written estimate before non-urgent work starts.

Sedation for this kind of treatment

If the painful tooth needs a root canal or extraction and sitting through it worries you, say so when you call. Local anesthetic numbs the tooth at the visit. Nitrous oxide may be possible the same day. Oral sedation, IV sedation, and general anesthesia are scheduled for a later visit, not started on arrival.

Can you help if I have severe tooth pain tonight?

Call us. New-patient admissions run from 6 AM to 2 AM. If pain wakes you, does not respond to over-the-counter medicine, or comes with facial swelling, we treat it as same-day.

Should I put aspirin on the gum?

No. Aspirin on the gum burns the tissue. Use pain medicine by mouth, as the label directs, and a cold compress on the cheek.

Will the pain disappear once I arrive?

The aim is to find what is causing the pain and treat that cause so you can get comfortable. We do not promise the pain will vanish before the cause is treated.

Read this as education

These are common patterns, not a diagnosis of your tooth. Your dentist determines the cause during an examination.

Admissions reopen at 6 AM. Leave your details and we'll call you back when the clinic opens.
