Why does my tooth hurt so much
Severe tooth pain can come from inflamed pulp, an abscess, a crack, exposed dentin, gum disease, or pressure around an erupting tooth.
The short answer
Severe tooth pain commonly comes from inflamed or infected pulp, a dental abscess, a crack, exposed dentin, gum disease, or an erupting tooth. The pattern of pain and an examination help identify which tissue is involved.
What is the direct answer?
What does this question mean?
The pulp contains nerves and blood vessels inside the tooth. When inflammation raises pressure within the rigid dentin walls, temperature, biting, or spontaneous nerve activity can produce intense pain that may spread to nearby areas.
What can you do next?
Rinse gently, keep food away from the painful area, and use a cold compress on the cheek if it helps. Do not place heat, chemicals, or aspirin on the tooth, and arrange dental assessment instead of masking worsening symptoms.
When should you seek dental care?
Obtain urgent care for facial swelling, fever, pus, difficulty swallowing or breathing, inability to open the mouth, or pain that prevents sleep or eating. Pain after injury or a tooth that has changed colour also needs prompt examination.
What should you ask the dentist?
Ask whether the pulp, root, periodontal ligament, gum, or jaw joint is causing the pain and which tests support that conclusion. Ask whether treatment is a filling, root canal treatment, drainage, extraction, or another procedure.
Frequently asked questions
Why does pain spread to another tooth or the jaw?
Nerve pathways can make pain from one tooth feel as though it comes from nearby teeth, the jaw, or the ear.
Can severe tooth pain disappear without treatment?
Pain can lessen if pressure drains or the pulp loses vitality, but the underlying cause may remain and still requires assessment.
