Receding gums: Receding gums don't grow back you need to have a periodontist find the cause so it doesn't continue exposed roots may be sensitive to hot or cold when the gums recede the underlying bone also recedes so that can weaken the bone support of the teeth please switch to asoft brush.

Depends: Usually the gum will not come back on its own. But there may be some corrective options available with a specialist. See your dentist.
