    shall look for another color. If it harmonizes, but the shade does not seem to be exactly right, we can easily determine which of the eight yellows harmonizes best, and order therefrom. If it does not harmonize, it will be well to try sample tooth No. 12 which is a light blue, under the lip in the same way. Should blue harmonize with the complexion and the shade be a trifle too dark, sample tooth No. 6 may be put into position since it is lighter than No. 12 and has nearly all of the blue in the incisal edge. Should No. 12 not be dark enough, Nos. 13 and 18 will offer darker blues. If neither the yellow nor the blue suit the complexion. No. 11 or No. 14 may be tried in the same way. Should these be of the right color but not dark enough in shade, No. 22 is a dark gray and will supply the lack. Should none of these be what is desired, No. 17 may be tried for a green, No. 23 for a blend of green and brown, Nos. 24 and 25 as browns. If after careful consideration none of the above colors are suitable, it will probably be found that one of the whites will be what Is desired and for this purpose No. 4 which is a milk white, and No. 3 which is a blue white, will probably answer. A method for determining the color which is in successful use by many dentists is to determine what color predominates in the complexion first. They do this by laying the shade guide teeth, one at a time, against the cheek and determining which of the colors pre- sented there harmonizes best with the skin. They also determine which of the shades of that color is most harmonious. If this shade now be tried under the lip it will usually be found to pro- duce a very pleasing effect in combination with the rest of the face. In selecting teeth do not work too rapidly, but do not look too long at one time. Five seconds is as long as the vision is color true at one time. Many short trials are preferable to fewer long ones. The results from it are so very much more satisfactory than from less careful selection of teeth that it well repays the exercise of what little patience is required to learn this part of prosthetic work.
