Time to call the dentist!

A few days ago Tyler was drinking his sippy cup and he started crying and was holding his mouth, and threw his sippy cup across the room. Of course i looked in his mouth and didn't see anything...well yesterday i was playing with him and on the top left he has a tooth with a grey/black spot...OMG he has his first cavity :( So monday we will be calling the dentist, and seeing what we can get done so my baby has NO more pain!!!
