with the ZB trial, I used to make the mouth aperture without the membrane and then i was “digging” from both left and right side, here is the result:
Derkomai some sweet advice there, but one thing id like to add bout the teeth in back, they dont neccessary need to be flat teeth, since flat molars are more on the omniovirous side of things. If you look at dogs they have mountain like shaped teeth in the back. Which enables them to tear flesh off of bones, and or crush bones completly when dealing with larger prey.
If your dragon is more lizard-like, then T-Rex teeth are fine. They are bladelike, and predatory dinos had no molars. Gastroliths in their belly helped pulp the meat for digestion after it was bitten off.
So usually, for dragon heads, a good mix of dino, lizard ( croc and alligator ) are always a good source of inspiration.
Carnivore molars are spikey, because they are designed to masticate and chew up stringy tough connective tissue. Herbivore molars are flatter, dealing with grinding plant matter. Omnivores are somewhere in between.
wow thx alot Soulstealer! The pics really help. Ill try to get the model updated soon. I’ll be sure not to dissapoint you guys, and girls 
in fact, it depends of what your dragon will eat, or whatt style do you prefere!
cause you can make crocodile like teeth too or range of many small identique teeth (see godzilla)
here is the 1/6 model!
or teeth wich recess (??) each other
here is the more evident picture I have found, even if tyhe mouth is open:

but you started with large teeth, so it’s as you want but it would be logical to continue like this! (and thank you Soulstealer I was speaking of this type of jaws, but not clarly apparently! XD)
what? you mean no up?
did you give up slayir?
No havent given up, I’ve been makin little progress because of alot of school assignments and tests. The small updates arent worth putting up, so I’ll post the final update. School sucks…
XD
good luck for the tests!
