Inter proximal spaces | area between each tooth normally filled with gum tissue (inter dental papilla) |
Embrasures | any curvature toward or away from the contact area, (spillways) helps food deflection |
Crest of curvature | determines the direction the food is being pushed toward the CEJ when chewing |
what bad about malpositioned teeth? | effects how plaque builds up, food gets caught, and allows plaque into hard to reach places. |
