Faces not showing in Solid Shading

I am having some face issues. I have attached a file with my model of a wheel with teeth. If I render, the object is clearly solid, yet when I view my model in Solid Shading, the window shows the wire cage of the wheel. I double-checked my Normals, but it didn’t seem to work. I have never had this issue before. Does anyone know how to solve this?

In the properties panel…
Object->Display->Type: it is currently set to Wire, change it to Textured or Solid.

Thanks a lot. I should have checked that.
