If you are experiencing sudden, severe discomfort, accompanied by swelling, there may be an infection in your mouth. If an infection is present, your dentist will likely prescribe antibiotics right away before attempting to perform root canal therapy or other restorative procedures.
If an abscess is present, a localized pus formation might be seen at the root end of the tooth. If the condition is acute and there is an infection present, your dentist will likely prescribe antibiotics prior to attempting any further treatment.
If your tooth is knocked out, control the bleeding by applying direct pressure with a cold compress. Recover the tooth that has been knocked out (without touching the root) and very gently place it back in the socket. It is possible to re-implant the tooth within 30 minutes of being knocked out. If you are uncomfortable with this, or if you see debris on the root surface, place your tooth in a glass of cold milk and bring it to your dental office immediately.
A facial fracture is an injury that results in broken bones to the face.
Immediately go to the emergency room at your nearest hospital.
