Toothache causes and urgent care
Toothache usually comes from decay, inflammation, a crack, gum disease, or an erupting tooth and needs assessment if persistent.
The short answer
Toothache is commonly caused by decay reaching the dentine or pulp, a cracked tooth, gum inflammation, an abscess, or pressure from an erupting tooth. Pain that is severe, persistent, or accompanied by swelling needs prompt dental assessment.
Why does toothache need a dental diagnosis?
A toothache is a symptom, not a diagnosis. Sharp pain with cold can reflect exposed dentine, lingering or spontaneous pain can indicate pulpal inflammation, and pain on biting can occur with a crack or inflammation around the root.
What can you do while arranging dental assessment?
Rinse gently with warm water, clean around the tooth with a soft brush and floss, and use a cold compress outside the cheek if swelling is present. Avoid placing aspirin or concentrated chemicals on the gum, and arrange an examination rather than relying on pain relief alone.
Which signs mean toothache needs urgent care?
Seek urgent care for facial swelling, fever, difficulty swallowing or breathing, reduced mouth opening, or swelling spreading toward the eye or neck. Arrange a dental visit soon when pain lasts beyond a short episode, wakes you, follows trauma, or returns after medication wears off.
How can the dentist determine which tissue hurts?
Ask whether the pain comes from the pulp, root tissues, gums, or a neighboring tooth, and whether an X-ray or vitality test is needed. Ask which treatment preserves the tooth, what temporary care is appropriate, and what warning signs require same-day review.
Frequently asked questions
Can toothache disappear without treatment?
Pain may temporarily fade while the underlying decay or infection remains, so improvement does not prove the tooth has healed.
Why does cold trigger a toothache?
Cold can reach exposed dentine or an inflamed pulp through a cavity, worn enamel, or a leaking filling.
