lies through one's teeth

Shamelessly speaks falsehoods

To lie through one's teeth is to lie brazenly and completely, without shame or hesitation: He looked me in the eye and lied through his teeth.

The phrase suggests not just dishonesty but boldness—the liar shows no discomfort, making the deception all the more brazen.
