Transverse Ridges
First four lower cheek teeth, nose would be
toward the right.
 |
A. First cheek tooth, undulations usually
very short or not present. |
 |
B & C. Second/third cheek tooth, ridges
are becoming pointed. (Mildly exaggerated) |
 |
D. Forth cheek tooth, undulations normal,
rounded top. |
 |
Every high point on one tooth has a
corresponding low spot on the opposing tooth. See the second picture below. |


Exaggerated transverse ridges meshing with the corresponding
"valley" on the opposing tooth. Normally the tops of the ridges would
not touch the opposite row of teeth when the jaw moves front to back in the
resting position. back
