My tooth was knocked out. If I have no milk, can I put it in a sports drink?

We do not recommend it, because sports drinks are acidic and can damage the cells on the surface of the tooth root. For storing a knocked-out tooth the best options, in order, are 1) milk (most recommended), 2) saline, and 3) holding it under your tongue in your own mouth; avoid tap water and dry tissue. Do not touch the root - hold only the crown. If the tooth came out whole, the chance of saving it is higher the sooner it is replanted, ideally within 30 minutes to an hour, so the most important thing is to come to the clinic immediately with the tooth stored properly.
