Advice on dental appointment

So, for those who already know my sweet girl has an appointment the 24th for some dental work. I am a NERVOUS WRECK. I cried at her last appointment just with vaccinations and a nail trim 😭 plus she had adverse reactions to the vaccines last time. 😢

So, I am wondering if there's anything I can do to prepare Ruby's body for what is to come. I want to give her the best chance possible for a quick recovery. Just anything I can do to make this appointment ANY easier for her.
