How to reduce pain from cavity
Cavity pain may ease briefly with trigger avoidance and suitable pain relief, but the decayed tooth needs dental treatment.
The short answer
Cavity pain can be eased briefly by avoiding triggers and using suitable label-directed pain relief, but the decayed tooth needs dental treatment to remove the cause.
How does a cavity weaken the tooth and cause pain?
A cavity is a bacterial-acid lesion that weakens enamel and dentine. If it reaches dentine, cold, sweet, or pressure can stimulate the pulp; deeper decay can inflame the pulp and produce lingering or spontaneous pain.
What can you do to protect the painful tooth?
Keep the tooth clean, rinse away food, avoid very hot, cold, or sweet items, and chew on the other side. Use pain medicine only if appropriate for you and as directed on its label or by a clinician, and do not put aspirin directly on the gum.
Which cavity pain symptoms need prompt care?
Seek prompt care for pain that lingers after a trigger, occurs without eating, wakes you, or comes with swelling, fever, pus, or pain on biting. Difficulty breathing or swallowing with facial swelling requires immediate medical help.
Can the pulp recover, and how deep is the lesion?
Ask how deep the lesion is and whether the pulp is still recoverable. Ask whether treatment requires a filling, pulp treatment, or removal, and what temporary measures are suitable until the appointment.
