A question for the experts:

We have a tile on the close wall that has been damaged over the years
by the hook for the door colliding with it. This has now worn away
the glaze into a channel. I appreciate that a cosmetic restoration
would be very difficult, but what could I do to prevent further
damage? I wondered about paint or epoxy resin adhesive or superglue,
or maybe some sort of patch like a bandage? Any ideas appreciated.

To prevent further damage you need to prevent further impact. Either by
restricting the travel of the door, or changing the hook location, or
applying some sort of protector to the tile (which would obviate the
need for restoration).

For restoration, fill the hole with Milliput, coloured if necessary,
then paint to match. It's surprising how little skill is needed to get
to the point where a repair is hardly visible.
