NBA's Andre Drummond Cops Iced-Out Custom Grill, Worth $20k!

New team, new bling!! At least, that's the type of wave Andre Drummond is on ... with L.A.'s newest star copping a brand new grill right after joining the Lakers!!!

TMZ Sports has learned ... the 6'10" big man decided he wanted his smile to be spotted from miles away ... so he hit up his guy, AP the Jeweler from Atlanta, to help him out with a new grill.

Since Drummond was still a Cavalier at the time, AP personally flew out to Cleveland back in February to get his molding and start the process.

Of course, Drummond's tenure in The Land ended shortly after placing his order ... but the timing couldn't have been more perfect -- he now had a new accessory for his big arrival in L.A.!!

AP -- who also made LaMelo Ball's grill -- tells us the 8-top, 8-bottom white gold piece is filled with 10 carats of VVS diamonds in a honeycomb set.

No word on how much Drummond paid for his teeth, but we're told a grill like this would cost anyone a solid $20,000.
