Tooth pain causes and next steps
Tooth pain can come from decay, a crack, pulp inflammation, gum disease, exposed dentine, or pressure around an erupting tooth.
The short answer
Tooth pain can come from decay, a crack, pulp inflammation, gum disease, exposed dentine, or pressure around an erupting tooth. The quality of pain, trigger, duration, and location help the dentist identify the likely source.
What can the timing and trigger of pain reveal?
Brief pain from cold may reflect exposed dentine or an irritated pulp, while lingering heat or spontaneous pain can indicate deeper pulpal inflammation. Pain on biting may involve a crack, inflamed ligament, or an infection around the root.
What should you record before your dental appointment?
Note the trigger and timing, rinse gently, clean between teeth, and avoid chewing on the painful side. Examination may include percussion, cold testing, bite testing, gum probing, and radiographs, followed by a filling, crown, root canal, extraction, or gum treatment when indicated.
When does tooth pain warrant a dental appointment?
Pain that lasts, worsens, interrupts sleep, or returns after medication deserves a dental appointment. Facial swelling, fever, pus, spreading redness, or difficulty swallowing or breathing calls for urgent care.
What should you ask about the tissue causing pain?
Ask whether the pain comes from the pulp, ligament, gum, or a neighbouring tooth and what tests support that conclusion. Ask which treatment addresses the cause and what changes mean the problem is becoming urgent.
Frequently asked questions
Why can tooth pain feel like it comes from another tooth?
Nerves from nearby teeth can produce overlapping signals, so the dentist compares several teeth with tests and imaging.
Can tooth pain disappear without treatment?
A symptom can fluctuate, but disappearance does not prove that decay, a crack, or pulp disease has healed.
