Partial Tongue Pain from Dentures?

I recently had to remove a bottom tooth due to an accident. My partial was a bit painful so I had my perio cut it down some and filed. However this caused it to become loose on one side and the floor ("gum" part) is causing soreness from the constant rubbing and thickness. Can I use a soft reline to remedy this? Will it make my partial smooth and less irritating? Thank you for any help on this.
