Yes, but it depends highly on how much damage there is and where the dent is. Severe dents on parts such as the lip plate, keys, and tone holes will likely stay there forever. Call it “battle damage,” if you will. Another thing that will affect dent repair is the type of metal used in making the flute. The more malleable the metal is, the easier it will be to remove dents. But whenever a dent is possible to be removed, don’t expect that you will see the instrument as if a dent was never there. There will always be a slight variation in the way the repaired dent looks from the rest of the flute.
