The most common and idiomatic word to describe this situation is chattering.

From WordNet:

chatter: click together repeatedly or uncontrollably

"Chattering teeth"

    I'm not sure I can accept that without a reference and a few cites.

    Getting there, @deadrat. I usually post the answer first and then go get some sources to support it.

    I wasn't serious. I guess I'm going to have to learn how to use emoticons.

    I didn't know that you were kidding, but it didn't matter: you were absolutely right, and at no point was I offended. I post comments like yours all the time, and I wouldn't like to make a hypocrite of myself! I don't like to post answers which are supported solely by the implicit notion of "... take my word for it!".

    Absolutely right? No, not if you took me seriously.

Chatter is the word you are looking for:

Chatter (teeth):

  • If your teeth chatter, they knock together repeatedly because you are very cold or frightened:
    • I could hardly talk, my teeth were chattering so much.

Cambridge Dictionary

I've also heard Clatter used for this.

A continuous rattling sound as of hard objects falling or striking each other:

From Google books the following quote

“'Who are you?' I asked through clattering teeth. I was shivering from head to toe.

    That is definitely a word that describes a sound, but I don't think I've ever seen it applied to the activity of teeth when one is cold or shivering.

    Google Ngram viewer suggests it's rare relative to Chattering but does get used. I must have read a lot of books from the 1890s. (;
