Reduce cavity pain
Cavity pain may ease briefly when triggers are avoided, but decay must be treated to remove its cause.
The short answer
A cavity is decay that has damaged enamel and may involve dentine or the pulp.
How can deeper decay affect the tooth pulp?
Bacterial acids weaken enamel; deeper decay can inflame the pulp and cause lingering or spontaneous pain.
What can you do to reduce cavity pain today?
Rinse gently, avoid hot, cold, sweet, or sticky triggers, and use suitable label-directed pain relief. Do not put aspirin on the gum; treatment may require a filling or root-canal care.
When does cavity pain need urgent dental care?
Book care if pain returns, lingers, wakes you, or comes with swelling; fever or breathing difficulty is urgent.
What should you ask about restoring the painful tooth?
Ask how deep the decay is, whether the pulp is involved, and whether the tooth can be restored.
Frequently asked questions
Can a cavity stop hurting by itself?
Pain can change while decay remains, so improvement does not prove healing.
Can I seal it at home?
No. Home products cannot remove decay or assess the pulp.
