If I broke a tooth biting to a kernel of the supermarket’s brand of popcorn, can I pursue the supermarket chain to pay my dental bill?
It is unlikely that you could win this case. To win, you'd have to prove that it was unreasonably negligent for there to be a kernal in a bag of popcorn. But whether or not you have seen a kernal in a bag of this popcorn before, unpoppwed kernals are not unual or uncommon in popcorn; therefore, it is not likely to be found to be unreasonably careless for one to be included in this bag, since sometimes the corn does not 100% pop.
