Me too. I think the OP has been lucky up until now. 1 missing tooth in a girl is not the end all. Most breeders prefer full dentition from a boy they're breeding to.
Things can skip generations both good and not so good. You need to look at the dogs in the pedigree if there are dogs with missing teeth above sire and dam it can come out, so the answer is yes.
I've gotten offspring with full dentition, an extra adult tooth, and a few missing premolars from parents that had full dentition themselves and have had a few missing premolars. Roll the dice and hope for the best.
It's one missing tooth, not the end of the world. And yes, you can get missing from parents who are full and you can get full from parents who have more than one missing.
