Dental emergency may include oral soft tissue injury resulting  due to tear or tooth fracture or jaw fracture or severe toothache due to dental caries. So first aid is necessary for such emergency condition.

Toothache

Rinse the mouth vigorously with warm water to clean out debris. Use dental floss to remove any food that might be trapped between the teeth. If swelling is present, place cold compresses on the outside of the cheek. (Do not use heat or place aspirin on the aching tooth or gum tissues.) See your dentist as soon as possible.

Knocked-Out Tooth

f the tooth is dirty, rinse it gently in running water. Do not scrub it. Do not attempt to replace the tooth into the socket. This could cause further damage. Wrap the tooth in a clean cloth or gauze and immerse in milk or cool water. Go immediately to your dentist (within 30 minutes, if possible.) Don't forget to bring the tooth

Fractured Tooth

Gently clean dirt or debris from the injured area with warm water. Place cold compresses on the face, in the area of the injured tooth, to minimize swelling. Go to the dentist immediately.

Object Wedged between teeth

Try to remove the object with dental floss. Guide the floss carefully to avoid cutting the gums. If not successful in removing the object, go to the dentist. Do not try to remove the object with a sharp or pointed instrument.

Fractured jaw

immobilize the jaw by any means (handkerchief, necktie, or towel). If swelling is present, apply cold compresses. Call your dentist or go immediately to a hospital emergency room.

When tissue is injured

Injuries to the inside of the mouth include tears, puncture wounds and lacerations to the cheek, lips or tongue. The wound should be cleaned right away with warm water, and the injured person taken to a hospital emergency room for the necessary care. Bleeding from a tongue laceration can be reduced by pulling the tongue forward and using gauze to place pressure on the wound.
