Is there something you could do if a patient comes into your office with a knocked-out tooth?

The correct answer is C. Tooth avulsion is a medical emergency. The faster the tooth is reinserted the greater the likelihood of survival of the tooth. The patient or the doctor in the emergency room can try to reinsert it however an emergency visit to the dentist is always necessary in order to make sure that the tooth is reinserted correctly and to splint it to the teeth on either side to hold it in position. The tooth can be rinsed but should not be brushed and touching the root end should be avoided. During transportation, it should be placed in sterile saline, milk, or saliva. Baby teeth should not be reimplanted because this could damage the adult tooth growing underneath.
