What does "齓" mean?


I've found this kanji during Shodo practice. My teacher (Japanese) didn't know
the meaning (she recognized the Tooth bushu/radical but not the "word").

I tried to look it up on the electronic dictionaries I own, both Japanese and
Chinese, but while the kanji exists and even has a phonetic associated to it:

![From Tangorin.com](https://i.stack.imgur.com/OOWlO.jpg)

there is no actual meaning.

Finally I got something from a [Chinese online
dictionary](http://www.zdic.net/zd/zi/ZdicE9ZdicBDZdic93.htm). Allegedly (I
used Google translate on the whole page) it is an old ideogram for "Milk
Teeth".

Now the question(s):

  * Does this mean anything in Japanese? 
  * What would be the current Japanese way to indicate "Milk teeth"?




The character in question was originally composed of 歯 (teeth) and 巳 (child).
It represented children's teeth. This later became 齔 and 齓. 齔 is typically
preferred over 齓, so I will use it below. It has two primary meanings: 1) in
children, the replacement of old teeth with new teeth; 2) children of an age
in which they are loosing their old teeth and growing new ones.

There are several compounds:

  * 髫齔 (chōshin): a child around the age of 7 or 8
  * 齔髫 (shinchō): (in general) a child
  * 齔童 (shindō): children of an age in which they are loosing their old teeth and growing in new ones
