Ok, I’m gonna need you to stop talking nonsense, clearly, this is real life and we need to respect the strength of dragon teeth.

Well the fact that we have seen those same crystals break by just falling can tell that they aren’t even that solid to begin with, probably like sugar glass or even more fragile.

Then wouldn’t they just be called “glass”?

I doubt it. Glass, very specifically, is molten and reformed SiliconDiOxide. It is typically man(creature)-made, though obsidian crystals are often referred to as volcanic glass. Gem stones/natural crystals are (typically) rigid, repeating structures of specific elemental composition.

Ignoring all of that, the general structure of glass, as we are most familiar with it, is sheet-like and thin. Where most crystal structures, with exceptions, are some variation of cylindrical or pyramidal. If one was determined, they could snap a piece of plate glass with thier teeth, but crushing a gem stone would take far too much pressure for a human or pony jaw to muster.
Given the generic limitations of anatomy, I have always assumed that those dragons which chew thier gems either wield some form of passive magic which allows them to preemptively erode the stones or just passively heat the stones to destabilize thier structure enough to bite through it.
