What to do before you get here
Knocked-out tooth: pick it up by the top, not the root. Rinse it gently without scrubbing. If you can, place it back in the socket and bite on a clean cloth. If not, keep it in milk and call right away. Time matters.
Broken tooth: rinse with warm water, save any pieces, and use a cold compress on the outside of your cheek to ease swelling.
Toothache: rinse with warm water and gently floss to remove anything stuck. Don't put aspirin directly on the gum. Over-the-counter pain relievers taken as directed can help until you are seen.
Lost crown: keep it safe and bring it with you. Avoid chewing on that side.
