GTD asks if you have shoveling on incisors.

On my lateral incisors, I have 1st degree marginal ridges. Is this considered "shoveling" for the purposes of SWAMI?

If I choose "yes" on shoveling, SWAMI changes my GT to Teacher.

I found a pretty good article here:  http://www.uic.edu/classes/osci/osci590/10_1Non-Metric.htm

Are you asking about the canines? Those are not incisors.

incisor (plural incisors)

   1. One of the front teeth of mammals, between the canines.

"The mandibular lateral incisor is the tooth located distally (away from the midline of the face) from both mandibular central incisors"

I think what Lola is getting at is that in the book, it specifically talks about shovelling of the incisors (front teeth), as opposed to the lateral incisors (lateral to front teeth).

Ok... so the picture in the book looks nothing at all like the photos of shoveling on the Internet.

Are most people's 2 front teeth completely flat on the back?

Quoted from Gale D.

Those that don't have shoveling won't have the back flat. There will be a shovel-like shaped indentation, i.e. the center of the edge that first bites into food will be narrower than the part of the edge away from the center.

Think of a straight line. draw a 'smile' above it. That would be the view of a shoveled tooth from the biting edge (or draw a frown below if the visual orientation works better.)
