Only permanent teeth are implanted if they're knocked out. Baby teeth will be replaced with a permanent tooth soon.

Look at your knocked out  tooth, if the tooth has a sharp surface or shiny surface there's a chance that part of the root is still in your jaw, and re-implantation becomes less successful.

For the best chance for your tooth to embed itself back into the gum, your tooth needs to be implanted within 2 hours and you need to follow the following steps:

• Handle your tooth by the top - do not touch the roots.
• If your tooth has dirt on, gently rinse your tooth in a bowl of lukewarm tap water for less than 10 seconds.
• Don't rinse your tooth under running water, because too much pure water could kill the cells on the root surface that help re-attach the tooth.
