Most times they CAN be filled below the gum line...depending how far....gum tissue can be cauterized cutting off blood supply and allowing for a dryer field, not to mention better access...These areas usually prohibit composites due to moisture issues...however..amalgams work quite well in areas such as this....regardless what people may think or say...amalgams are still a reliable source of filling material...

when doing a filling the tooth must be completely isolated from water,blood,saliva,etc. If a cavity is below the gum it would be very difficult, if not impossible, to isolate the tooth to fill it properly Any sort of debris in the area where the filling is to be placed would cause the filling to fail and it would either fall out, or cause a larger cavity under the filling.
There may be other reasons too, but this is the first thing I could think of. Hope this helps!Good Luck!

Depends on far below the gum line you're talking. Mostly because it's VERY difficult to reach and IF you're able to get to it, it's very hard to determine if you've removed all the decay.

they can. it depends on how far, but they just pull back the gum and do the filling in most cases.
