It has been scientifically proven that the sense of smell can be improved or restored to its original level if it has been lost through an injury or infection.

This is because the olfactory nerves are extremely sensitive, and can detect many different odors. If they are damaged or infected, it can result in the loss of the sense of smell. It has also been shown that if you start training your sense of smell as soon as you get the infection or damage, you can prevent the loss of the sense of smell.
