Best dental clinic in 200 Feet Radial Road If you tooth is completely knocked out, it is crucial that you take the following steps: Pick up your tooth by the crown, making sure not to touch the root. Carefully rinse the tooth in water, not soap. Place the tooth back in its socket if possible. Place the tooth in milk or water or in your mouth, between your gum and cheek, to keep it moist if you are unable to place it in its socket. Bring your tooth to our office immediately.
