Caring for a Knocked-Out Tooth
If you knock out a tooth, hold the tooth only by the crown, never by the root. Immediately rinse the tooth in saline solution or milk, handling the tooth gently. Avoid using tap water, because it often contains chlorine, which can damage the tooth. Try to replace the tooth in its socket; if you can't, put it in milk, or place it between your gum and cheek. Seek immediate dental care.
