Thanks so much for your comments. She is due to see the vet for her annual check up in July. However, she has been at the vet 2x this spring because she was scratching herself------the solution was 3/4 teaspoon of children's Benadryl once a day. The pollen here in New England has been terible this year.
When I bring her to the vet, he checks her teeth to see that they are OK.
I may just bring her to the vet just to make sure she is OK. I can't believe she lost a tooth!
Hope your fur baby/babies is/are healthy.
