Kim Kardashian is showing off her kiddo Saint — but in a toothy sort of way … ’cause his little chompers are front and center for everyone to see!

The reality star posted an Instagram photo Sunday that showed her alongside 9-year-old Saint, who was flashing a bloody smile with one of his front teeth about to fall out, and another one missing.

Pretty gnarly, but Kim made light of it all with a cute caption … “The tooth fairy has been good to us 🦷🧚💸💎.”

In another IG pic … Saint gave us a big smile showing his new teeth coming in. Kim also posted a bunch of throwback snaps of Saint with 2 different grills. In one, he flashes gold Louis Vuitton teeth and, in the other, he flaunts titanium teeth, mirroring his rapper dad Kanye West.

But, Kim wasn’t finished … she also uploaded pics of her other children — North, 12, Chicago, 7, and Psalm, 6 — mostly with their gem-studded teeth.
