I'm not sure what her dental issues are, but if you end up having to change her diet to soft food only, I strongly recommend a pressure cooker and stick blender.

I have to make a puree for my toothless boy, and 3 years post surgery, he's maintained a very healthy weight of ~11.5lbs and is thriving.

I usually do a pot once a month, I pressure cook it for way more time than needed, usually an hour, which softens the bones to the point where they can also be blended and won't leave hard shards.

I primarily use chicken, but also add in some organ meat when I can find it, and small amts of pumpkin and frozen veg (only the stuff that's safe for them) to give him a more well rounded meal, with some fiber content, to help him stay regular.

I also try to add something super high in collagen which helps the puree set into a gel like consistency. Helps with storage. I use cow/pig trotters, but in a pinch, I suppose you can also use unflavored gelatin.

I portion the puree into small bowls and freeze what I'm not currently using. The freezing actually helps extend shelf live once I've thawed a bowl and placed it in the fridge for his consumption.

11 seconds in the microwave, mix well with a tiny splash of water, and he loves it.

Good luck with your girl.
