MUSCLES: ' I don't want to get confused, but when I look in my mouth I see
sharp-shaped "teeth", but when I look at your mouth I see funny
flat-topped "teeth"---right? '
Dr Skerpan: Actually, you don't see any WHOLE teeth at all. So, the third "crown"
in the question would be referring to the anatomical name for the
top-part-of-the-tooth. For example, you see the WHOLE-TOOTH
when the WHOLE-TOOTH is extracted. In reality, the WHOLE-
TOOTH is not just what you see above the gum-line. The WHOLE-
TOOTH is made up of the ROOTs PLUS the top, which is also called
the anatomical "CROWN".
MUSCLES: ' B-Wow-Wow-Wow a minute! Backup--let me see more pictures! '
MUSCLES: ' I like the idea of the "bone"! But what does the second "crown" in
the original question mean? '
Dr Skerpan: The second "crown" in the question adds to the confusion.
Sometimes you may hear it said that a tooth needs to be "crowned".
In this context it actually means that the top-part-of-the-tooth
needs to be "covered" with a crown--as we said before, when the
top-part needs rebuilding, protecting or reshaping. The "covering"
("crowning") acts to simulate a functioning-shape, and restore the
healthy-state on the top-part-of-the-tooth.
MUSCLES: ' Then it IS possible that a "crown" (or a lab-made "cap") can "crown"
(or "cover") a "crown" (or the "anatomical" top-part-of-the-tooth).
But I still like the idea of the "bone"! Can we talk more about that? '
Dr. Skerpan: We can discuss more about the bone later, when we tackle the
the "periodontal" aspect of dentistry.
