Hemp pulp paper can be made without chemicals from the hemp hurd. Most hemp paper made today uses the entire hemp stalk, bast and hurd. High-strength fiber paper can be made from the hemp baste, also without chemicals. The problem with today's paper is that so many chemicals are used to make it.
The numbers 1 through 8 and a unique symbol are used to identify the teeth in each quadrant. The numbering runs from the center of the mouth to the back. In the upper right section of the mouth, for example, tooth number 1 is the incisor (flat, front tooth) just to the right of the center of the mouth. The numbers continue to the right and back to tooth number 8, which is the wisdom tooth (third molar.)
The next tooth is number two and so on until reaching the last upper tooth. Numbering continues with the rear-most tooth on the lower left side. When your dentist attaches a letter to a number, he or she is referring to the side or surface area of a tooth.
