Assessment and monitoring
If symptoms are mild or unclear, assessment may help identify risk and decide whether monitoring is reasonable.
Tooth pain
Tooth pain can come from decay, cracks, gum problems, bite pressure, wisdom teeth or infection, and some symptoms need urgent dental advice.

Why does my tooth hurt, and does it need urgent attention?
Tooth pain can feel simple at first, but the cause is not always obvious. The same symptom can come from decay, a crack, bite pressure, gum inflammation, wisdom teeth, sinus pressure or infection, so the useful first step is to understand what has changed and whether the situation is urgent.
What you may be worried about
- The pain may mean the tooth cannot be saved.
- The problem may become worse if you wait.
- The treatment may be more involved than expected.
- You may be unsure whether this is an emergency or a routine appointment.
Common patterns people notice
- tooth pain
- toothache
- spreading pain
Possible causes
- Decay or a deep filling close to the nerve inside the tooth.
- A crack that hurts when biting or releasing pressure.
- Gum inflammation, recession or exposed root surfaces.
- Wisdom tooth pressure, food trapping or infection around the gum.
- An abscess or infection spreading from the tooth or surrounding tissues.
When to treat this as urgent
Urgency level: urgent
- Swelling in the gum, face or jaw.
- A fall, accident or knock to the mouth before the pain started.
- Fever, feeling unwell, or pain that is spreading.
- Trauma, a broken tooth, or pain after an injury.
- Severe pain that does not settle with usual pain relief.
- Difficulty swallowing, opening your mouth, or breathing.
What to do now
- Notice whether the pain is constant, triggered by biting, temperature-related, or linked with swelling.
- Use the urgent pathway if pain is severe, spreading, associated with swelling, or started after trauma.
- Book an assessment if pain keeps returning, wakes you at night, or does not settle.
What to avoid
- Do not place aspirin or other tablets directly on the gum or tooth.
- Do not ignore swelling, fever, difficulty swallowing, or pain that is spreading.
- Do not rely on antibiotics without a dental assessment of the cause.
When to arrange a dental assessment
- Arrange urgent assessment for swelling, trauma, fever, or severe pain.
- Arrange a normal appointment if tooth pain is mild but persistent, recurring, or hard to explain.
What a dentist may need to assess
- The tooth nerve, surrounding gum, bite pressure, restorations, cracks, and any signs of infection.
- X-rays or cold testing may be needed because symptoms alone cannot confirm the diagnosis.
- Whether the pain is reproducible with biting, percussion, temperature, gum probing or pressure on nearby teeth.
- Whether pain is coming from a tooth or from surrounding tissues such as gums, jaw muscles or sinus area.
Options that may be considered
Repairing the tooth
If decay, a leaking filling or a small break is involved, a filling or restoration may be appropriate.
Root canal treatment
If the nerve is inflamed or infected and the tooth is worth saving, root canal treatment may be discussed.
Removing the tooth
If the tooth cannot be predictably restored or infection risk is high, extraction may be the safer option.
Urgent infection management
Swelling, fever or spreading pain can shift the priority from routine diagnosis to urgent source control and escalation if needed.
Bite or crack investigation
Pain on biting may need crack testing, bite assessment and sometimes short-term stabilisation before a final restoration is chosen.
What we would consider before recommending treatment
- Where the pain is coming from and whether the nerve is involved.
- Whether the tooth is cracked, heavily filled or structurally weak.
- Whether there are signs of infection or spreading swelling.
- Whether the tooth can be restored predictably after treatment.
- Your timing, comfort, budget and long-term dental goals.
If it were our own teeth
If it were our own tooth, we would first want a clear diagnosis, then we would weigh whether the tooth can be saved predictably. Saving a tooth is valuable, but only when the remaining tooth structure, infection risk and long-term outlook make sense.
A sensible next step
If there is swelling, trauma, a fall or severe pain, use the emergency dental page. If the pain comes and goes or is mild but persistent, book an appointment so the cause can be assessed before it becomes harder to manage.
Possible next steps
- Monitoring, bite adjustment, a filling, root canal treatment, extraction, or referral may be discussed depending on the cause.
- If infection or swelling is present, the immediate plan may focus on controlling the source before long-term restoration decisions.
- If the diagnosis is uncertain, a review period, temporary stabilisation or further testing may be recommended before irreversible treatment.
- Review the urgent warning signs and decide whether the concern can wait for normal booking.
- Call the clinic if you need help deciding what to do next.
- Use normal booking when the concern is stable or planned.
- If symptoms are medically serious or worsening quickly, seek urgent medical help where appropriate.
Related questions
What if I cannot tell which tooth hurts?
Referred pain is common. A dentist may need to test several teeth and surrounding tissues before identifying the source.
Common questions
Can tooth pain go away by itself?
Some sensitivity can settle, but tooth pain that is worsening, recurring, or linked with swelling should be assessed because the underlying cause may still be present.
Does tooth pain always mean root canal treatment?
No. Tooth pain can come from several causes. Root canal treatment is only considered when the nerve inside the tooth is irreversibly inflamed or infected and the tooth is suitable to save.
When is tooth pain a dental emergency?
Tooth pain may be urgent if there is swelling, fever, trauma, a broken tooth, spreading pain or severe pain that does not settle.
Why does tooth pain sometimes move around?
Tooth nerves and surrounding tissues can refer pain. Testing several teeth may be needed before the source is clear.
What should I tell the dentist about tooth pain?
Explain when it started, what triggers it, how long it lasts, whether biting or temperature affects it, and whether swelling, fever or trauma is involved.
