What should you do if a child chips off a piece of a tooth crown in a fall?

Dear Sir/Madam! Keep the piece that has broken off (if you find it) in physiological saline. Since this is usually not at hand, it can be replaced with saliva that the child spits into a cup or plastic bag, or with milk. The cup or bag containing the fragment and storage medium can be cooled with cold water or ice. Do not rinse the fragment with water or alcohol under any circumstances and do not let it dry out. Bring the fragment with you to the dental office, where it will most likely be possible to bond it back to the tooth. If the fragment is not available, the dentist will replace the missing part with a suitable material. I wish you as few injuries as possible!
