First aid can protect the area while you arrange care, but it does not replace diagnosis or treatment.
Toothache
Rinse gently with warm water and floss to remove trapped food. Do not place aspirin directly on the tooth or gums.
Cracked tooth
Rinse with warm water. A cold compress on the face can help with swelling while you arrange prompt dental evaluation.
Knocked-out permanent tooth
Keep the tooth moist, handle it by the crown and seek dental care immediately. If it cannot be placed back in the socket without touching the root, ADA guidance includes milk, the cheek-and-gum area, or an ADA-accepted tooth preservation product as storage options.
