Final answer:
An avulsed (knocked-out) tooth may be saved if re-implanted promptly.
Step-by-step explanation:
An avulsed (knocked-out) tooth may be saved if re-implanted promptly. It is important to act quickly to increase the chances of successful re-implantation. Solutions like milk or saliva can help preserve the tooth until it can be re-implanted. Scrubbing the tooth or immersing it in an antiseptic solution is not recommended as it may further damage the tooth or affect the success of re-implantation.
