First, check if the child has lost consciousness or not. If the child has not lost consciousness, then the next step is to locate the tooth (Has the child swallowed it? Is the tooth in the lip? On the ground?). Once the tooth has been located, put the tooth in either milk, the child’s saliva, or water, and contact the office. The tooth will need to be re-implanted into the child’s mouth, so be sure not to transport the tooth to the office dry.
