Dental question about taxonomy:symptom:tooth-pain
Tooth pain can come from decay, a cracked tooth, pulp inflammation, gum disease, or another dental problem needing examination.
The short answer
Tooth pain is a symptom rather than a diagnosis, and common causes include decay, a crack, exposed dentine, inflamed pulp, or infection. The pattern of pain helps a dentist identify the source, but an examination is needed to choose treatment.
How can the pattern of tooth pain differ?
Pain may be brief and triggered by cold, sweet foods, or touch, or it may linger, throb, or arise without a trigger. The enamel and dentine transmit irritation toward the pulp, where nerves and blood vessels respond to inflammation.
What can you do until your tooth pain is assessed?
Rinse gently, clean around the painful tooth, and avoid chewing on that side until it is assessed. A dentist may inspect the tooth, test its response to temperature or tapping, examine the gums, and take an X-ray when indicated.
When should persistent tooth pain be examined?
Book dental care when pain persists, returns, interferes with sleep, or is triggered by biting. Seek urgent assessment for facial swelling, fever, difficulty swallowing, difficulty breathing, or swelling near the eye.
What can help identify the source of tooth pain?
Ask which tooth is causing the symptom, whether the pulp is involved, and what findings support the diagnosis. Ask about options such as a filling, crown, root canal treatment, gum care, or extraction when those treatments are relevant.
Frequently asked questions
Why does a tooth hurt when I bite?
Biting pain can occur with a cracked tooth, inflammation around the root, or a high filling, so the tooth needs examination.
Can tooth pain disappear by itself?
Symptoms can fluctuate even when the underlying problem remains, so improvement does not establish that the tooth has healed.
