So about a month ago we noticed a little white speck on the middle bottom gum of our then 4 month old.. She had been super fussy, drooling a lot, had a rash, red cheek, etc. so we were pretty sure it was a tooth coming through. She had the white speck for about 4 days and then it just disappeared and hasn't made a reappearance yet.. She is now 5.5 months... has this happened to anyone else??
