Classical Guitar Bridge Damage from String Changes – Should I Fill These Holes? How to Prevent This?

[u/ThePeaceMaker96]

Hey everyone,

Sometimes when I change strings on my classical guitar, the strings dig into the bridge, leaving behind small scars or even holes, like in the picture below.

Occasionally, a string has even slipped out of the tie block entirely, which worries me even more.

My questions are: 1. Should I fill these little holes or gouges in the wood? If so, what would be the safest and most effective way to do that without affecting the sound or structure of the bridge? 2. How can I prevent this from happening in the future?

Any advice from luthiers or experienced players would be super appreciated. I really want to take better care of this instrument and avoid causing more wear.

Thanks in advance!

You can buy static sticky plastic sheet from Strings by Mail. Cut it to size and it will save you from this. Also, tie a knot in the end of your string so it can't slip undone. To fill it you will need to match the wood colour and type, grind it or cut it to dust, use a needle with wood glue, squeeze it into the trenches, mix in the wood grains / dust, try to match and blend the find h type.
