I just noticed that our little Sheltie, Nora, has a broken tooth (Fourth Upper Premolar). Should have caught this earlier has my DW noticed our dog had been shaking her head a lot, which she was, but I just brushed it off. Looks like that was our dogs way have expressing she had an irritation/pain.
Hopefully our vet can get us in tomorrow sometime and get everything fixed. My biggest fear is that they will have to extract the tooth and will have to put her under anesthesia to do so. 
Many hugs for you and Nora! I hope all turns out well! You'll be in my thoughts!
we just put our cat through a dental, our first one ever, but because she is diabetic it was important to do. We knew the risks involved and went to a certified dental specialist. Our naive thinking was just a simple cleaning would do the job. Once the vet got in there, 8 teeth had to come out 
I wish we would have paid better attention to her before it got that bad ...
Thank you everyone. We went to our vet this morning and it was indeed broken tooth, a slab fracture as he called it. They are going to put her on anesthesia to extract the tooth. I just got the results of the blood work back and it sounds like her bUn levels are higher, but everything else is okay. Sounds like it could just be dehydration, but they said they would change the pain med to something else and keep her on the IV longer afterwards. We have decided to go ahead with the procedure even with the elevated level so I am even more nervous than I was before.
Nora is our little baby and I hate thinking negative thoughts so I'm trying to stay positive and hope and pray for the best.
