Dental question about taxonomy:symptom:tooth-pain
Tooth pain can come from decay, a crack, exposed dentin, inflamed pulp, gum disease, or pressure, and treatment depends on the cause.
The short answer
Tooth pain is a symptom rather than a diagnosis, and common causes include decay, a crack, exposed dentin, gum inflammation, or an irritated dental pulp. A dentist locates the source with history, examination, bite tests, temperature tests, and X-rays when indicated.
What is the direct answer?
What does this question mean?
Sharp pain with cold or sweets may reflect exposed dentin or early pulpal irritation, while lingering heat pain or spontaneous throbbing can indicate deeper inflammation. Pain on biting can involve a crack, a high filling, or inflammation around the root.
What can you do next?
Rinse gently, clean around the tooth, avoid chewing on the painful side, and note whether cold, heat, sweets, pressure, or lying down changes the pain. Do not put aspirin or other caustic substances on the gum; use only suitable pain relief according to the label or clinical advice.
When should you seek dental care?
Arrange prompt dental care for pain that persists, returns, wakes you, or is triggered by biting. Facial swelling, fever, pus, a spreading bad taste, or difficulty breathing or swallowing requires urgent assessment.
What should you ask the dentist?
Tell the dentist when the pain began, what triggers it, how long each episode lasts, and whether a filling, injury, or recent treatment preceded it. Ask whether the tooth needs a filling, crack management, root canal treatment, gum care, or removal.
Frequently asked questions
Why does cold hurt one tooth?
Cold can reach exposed dentin or stimulate an inflamed pulp, but examination is needed to distinguish sensitivity from decay or a crack.
Can tooth pain go away by itself?
It can fluctuate, but temporary relief does not prove the cause has resolved; persistent or recurring pain needs dental assessment.
