Tooth bud???

Little boy will be five months Jan 6. He has been drooling like crazy and tonight we saw three little white spots like the one below (look to bottom right in pic). One on bottom, two on top but off to the sides. Are these teeth coming in or is something else going on? No fever, but he’s been fussy
