Due to the depth of the dent and the low height of the other frets, the damaged fret was removed and replaced with the matching profile fretwire.
The masking tape was removed after the fret recrown, to check the visual appearance of the new fret. The board was then remasked for the polish, after the polish, the board was treated with lemon oil to condition the wood.
The end result was a perfectly level new fret, that blended in well with the original frets that had been installed when the guitar was made.
