You likely need a neck set. If your Kent is a nylon string classical it probably has a "spanish heel" which makes a neck-set impossible. I have heard of old timers removing the fingerboard and installing a tapered shim the length of the neck to raise fretboard at the sound hole end and restore proper action. If the neck is warped, it is possible to heat it gently and apply pressure to slowly bring it back until it is straight. Both of these repairs well exceed the value of the instrument...but I understand the attachment.
