So my son is a couple days shy of 16 months and tonight when i went to brush his teeth I noticed that one of his front teeth is chipped, like the corner. I'm freaking out saying we need to call a dentist cuz i don't want something to cause it to rot or to be painful for him but of course my dh is calm as always saying it will be ok. I don't know if he bit something that chipped it (he's still biting everything) or if when he fell down today he hit his mouth.... I just don't know. Any advice?
