Will a toe nail grow back?

Yes, a toenail can grow back after it has been lost or removed, although the process may take several months. The regrowth typically occurs at a rate of about 1 millimeter per month. However, the new nail may differ in appearance or texture from the original, especially if there was trauma to the nail bed. If there are concerns about nail regrowth or any complications, it's best to consult a healthcare professional.
