How can you temporarily stop a cavity from hurting?
Rinse, avoid triggers, and use suitable pain relief temporarily, but a painful cavity needs treatment to remove decay and protect the pulp.
How does mineral loss from plaque acids cause a cavity?
A cavity is mineral loss caused by acids from plaque bacteria. Pain may begin when decay reaches dentine and may become spontaneous or lingering when inflammation reaches the pulp inside the tooth.
What can you do now to protect a painful cavity?
Keep the area clean, avoid very hot, cold, sweet, or hard foods, and use a pain medicine only if it is suitable for you and taken as directed. Do not put aspirin on the gum, because it can injure soft tissue.
When should recurring cavity pain be assessed?
Book prompt care for recurring or spontaneous pain. Facial swelling, fever, a bad taste, difficulty opening the mouth, swallowing, or breathing requires urgent assessment.
Which treatment options could protect this tooth?
Ask how deep the decay is and whether a filling, indirect restoration, root canal treatment, or extraction is needed. Ask what symptoms indicate that the pulp has become infected.
Frequently asked questions
Can a cavity heal by itself once it hurts?
Early mineral loss can sometimes be managed, but a painful cavity needs examination to determine its depth.
Why does a cavity hurt at night?
Pulp inflammation can cause spontaneous or positional pain that becomes more noticeable when resting.
