For a person who has had a tooth knocked out, what action should you take?

The correct action when dealing with a knocked-out tooth is to pick up the tooth by the chewing surface and rinse it gently. This method is crucial because it helps preserve the tooth's viability for possible reinsertion. Rinsing removes any dirt or debris without damaging the delicate cells on the root surface that can help in regenerating the tooth's attachment if reinserted soon.

Handling the tooth by the chewing surface minimizes the risk of damaging the root, which is key for the success of reattachment. After rinsing, it is important to keep the tooth moist; placing it in a container with a small amount of milk or saline solution can help preserve it until the person can see a dentist. This approach maximizes the chances of saving the tooth.

The focus is on immediate care for the tooth and ensuring the conditions for its longevity outside the mouth are optimized, guiding proper dental intervention as soon as possible.
