If an adult tooth gets completely knocked out (avulsed):
- Retrieve it, if possible, and hold the tooth by the crown (the white enamel part) being careful not to touch the root.
- Rinse the root in clean cold water if there is any dirt etc. on it but do not scrub the tooth or remove any of the attached tissue.
- Replant the tooth back in its socket to maintain moisture and increase the chances of a dentist successfully being able to treat the injury.
Replanting the avulsed tooth within 5 minutes ensures the best outcome, ligaments attaching the tooth to surrounding bone are still present on the root and can reattach as the body will still recognize it as its own. Try gently biting down on gauze or wet tea bag to keep the tooth in place and apply sustained pressure.
If the tooth can’t be replanted, it can be stored in a cup of milk or salt water to keep the root moist or even in your own saliva, carefully holding it between cheek and gum. Control bleeding with pressure and head straight to the dentist, with the tooth.
The above is for adult teeth only. Do not attempt to replant baby teeth as it could interfere with underlying permanent tooth health. Apply direct pressure to control bleeding and see a dentist as soon as possible.
