Because it isn't natural
Many rodents such as rats and mice are laboratory-bred hairless animals, deliberately bred so in order to facilitate various testing methods. If your rat is one of these, the hair will not grow back; it is a hairless breed. If your rat was born with hair and has lost it for some reason you will need to consult a vet, since its condition could lead to health problems for your pet.

Growing an ear on a mouse involves a process called tissue engineering, where a biodegradable scaffold in the shape of an ear is implanted under the skin of the mouse. Cells taken from the mouse's own body or from another source, such as a 3D printer, are then added to the scaffold where they grow and form the ear shape. The scaffold eventually biodegrades, leaving behind a functional, biological ear on the mouse.
The structure of the human ear is more complex than that of a rat's ear. The human ear has three main parts: the outer ear, middle ear, and inner ear, which work together to process sound. In contrast, a rat's ear is simpler and has a more basic structure with fewer components.
A rat's teeth continue to grow.
