Dental question about observed-topic:toothache
Severe toothache can come from decay, a cracked tooth, inflammation inside the tooth, or an abscess and needs timely dental triage.
The short answer
Severe toothache needs timely dental assessment because decay, a crack, inflamed pulp, or an abscess may be involved; facial swelling, fever, or swallowing difficulty makes it urgent. Temporary comfort measures do not remove the dental cause.

What is the direct answer?
What does this question mean?
Tooth pain is a symptom produced by irritated or infected pulp, the living tissue inside the tooth, or by inflamed tissues around the root. Pain on biting can suggest a crack or inflammation around the root, while lingering hot or cold pain can indicate pulpal inflammation.
What can you do next?
Rinse gently with warm water, remove trapped food with floss, and use only pain medicine that is suitable for you and taken exactly as its label directs. Avoid placing aspirin or chemicals on the gum, and avoid chewing on the painful side until examined.
When should you seek dental care?
Contact a dentist promptly for severe, recurrent, or night-waking pain, especially with swelling, a bad taste, pus, or tenderness to biting. Go to emergency care for swelling that threatens breathing or swallowing, or swelling spreading toward the eye or neck.
What should you ask the dentist?
Ask which tooth is responsible, whether an examination and dental radiograph are needed, and whether the treatment is a filling, root canal treatment, extraction, or drainage. Ask what warning signs should prompt immediate return.
Frequently asked questions
Can a toothache go away without treatment?
Pain can temporarily settle even when disease remains, so a quiet tooth is not proof that the cause has resolved.
Does every severe toothache need antibiotics?
No. Treatment depends on the dental diagnosis; antibiotics do not replace removal of decay, drainage, or definitive tooth treatment when those are indicated.
