What happens if your teeth hurt
Tooth pain signals irritation or inflammation in a tooth or nearby tissue, and the next step is diagnosis before the cause worsens.
The short answer
Tooth pain signals irritation or inflammation in a tooth or nearby tissue, and the next step is diagnosis before the cause worsens. Causes include decay, a cracked tooth, exposed dentin, pulp inflammation, an abscess, gum disease, or referred pain.
What happens inside a tooth when pain persists?
The pulp contains nerves and blood vessels inside the tooth; inflammation there can produce lingering heat or cold pain, spontaneous pain, or pain that wakes you. Pain on biting may involve the crack, ligament around the root, decay, or an infection near the root tip.
What can you do now to ease tooth pain safely?
Rinse gently, keep food away from the sore area, avoid extreme temperatures, and clean normally without forcing a painful space. A dentist may inspect the tooth, test cold or tapping, check the bite, and take an X-ray before choosing a filling, root canal treatment, drainage, extraction, or gum care.
When should ongoing tooth pain be checked by a dentist?
Arrange an appointment for pain lasting more than a brief trigger, pain that returns, or sensitivity with swelling, fever, bad taste, or pain when biting. Seek emergency medical care for swelling that affects breathing or swallowing or spreads toward the eye or neck.
What should you ask about the source of your tooth pain?
Ask which tooth and tissue are causing the pain, what the examination and X-ray show, and whether the pulp is recoverable. Ask which treatment removes the cause, what to do until treatment, and which symptoms require urgent review.
Frequently asked questions
Why does a tooth hurt with cold?
Cold can stimulate exposed dentin or an inflamed pulp; the duration of the pain helps the dentist assess the cause.
Can tooth pain disappear on its own?
Pain may fluctuate or stop if the pulp loses vitality, but the underlying tooth problem can remain and needs assessment.
