lying through one's teeth

Shamelessly telling falsehoods

To lie through one's teeth is to lie boldly and shamelessly, with full knowledge of one's own dishonesty: He stood there lying through his teeth about where he'd been all night.

The phrase suggests the lie is so brazen it practically shows on the liar's face—teeth bared in a false smile while speaking falsehoods.
