Compare the three pictures.
The middle picture is taken out of the pink book. And shows the three back double molars and two tiny pre molars in the front and you can see top line with bottom.
This is the best way I could describe it,
The top picture shows the places the two pre molars should be (blue arrows and also this is pointed with his pointer
The bottom picture shows the 3 double molars, they have a double crown on top when you look at the ariel photo you will see this, and each molar have a double root, if you look where the yellow arrow is and look to the top photo you will see the double root.
You can also see the bone swelling under the teeth if you compare to the should be photo and her x ray.
