Small Teeth Pass Overview - Baldur's Gate 2
Small Teeth Pass is a zone that unlocks on your World Map during Chapter 6 after leaving the Underdark. You need to pass through this zone and exit to the south in order to unlock the next map, the North Forest zone, on your World Map. There is nothing on this map worth mentioning, it's essentially a transient map that you'll be spending less than 5 minutes on before moving to the next one.
The only thing unique about this map is the enemies you encounter here will change depending on whether it is day or night. During the day you'll encounter Orcs but during the night time you'll find Wolfweres throughout the area. None of these enemies drop anything of value though.
