cutting a tooth...question

MJN9510

DD got her two bottom teeth at 6 months and now one of her top teeth just broke through this past week.  i cant remember this happening when she got her bottom teeth, but she seems to be uninterested in eating this week.  I am wondering if it is related to cutting a tooth or completely unrelated.  When i try to feed her baby food, she takes maybe 2 or 3 bites and then refuses.  It isnt just certain foods, it is ALL...even the ones she usually loves.  Also, she has not been taking much of her bottles either, about 3 to 4 ounces at a time is all she will take.  It is almost like she has no appetite.  i have also tried introducing table foods and she is completely uninterested.  HELP!  What do you think it could be?
