What is the direct answer?
What does this question mean?
Topical gels act mainly on the mouth lining where applied. Tooth pain often begins in dentine, the pulp, or tissues around a root, so surface gel has limited reach.
What can you do next?
Use only a product labelled for oral use and follow its directions. Do not pack gel into a cavity or apply large amounts; arrange dental treatment for the cause.
When should you seek dental care?
Seek prompt care for severe pain, swelling, fever, pus, or pain that wakes you. Swelling near the eye or neck, or trouble breathing or swallowing, is urgent.
What should you ask the dentist?
Ask whether pain comes from exposed dentine, pulp inflammation, infection, or gum tissue, and what treatment removes the cause.
Frequently asked questions
Can this symptom be treated at home?
