Tyga drops 45 racks on new grill

Tyga just got a new jewelry store … in his mouth.

Celeb jeweler Ben Baller just hooked Tyga up with the chompers … dripping in 1400 diamonds.

At $45,000 and 18 carats … it’s the most expensive grill Baller’s ever made.

On the other hand … never a good idea to have more diamonds than your girl.TMZ
