There is an De-Bogging kit listed in the ICO Chapter 13-10-...
and there is a procedure in the AMM Chapter 09-10-... which tells the Engineers how to use it.
It's not an difficult task and can be done forward or backwards, depends which direction is easier to access.
The Landing Gear is designed and tested for these kind of "accidents"!
