Blu-ray scratches on label side

[mwales]

I have twin infants that have on a few occasions got a hold of PS3 games. They have teeth now, and I have a few discs with small scratches.

The scratch protection on the bottom side of the disc is awesome. Once I clean the drool and fingerprints off the disc, the bottom looks perfect, no damage at all. I'm cleaning with water and paper towel.

But on the label side, they have actually put a small hole in the label/foil. You can actually see light come right through the label.

AFAIK, scratching the label on a CD will make it unplayable since it needs the reflection of the foil. I figure there must be a difference in how BD and DVD works though since they have multiple layers. Do label scratches effect BD or DVD mediums?
