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.
