Cavities 🙂

Hey all!! 
So, despite my frequent brushing, flossing, and rinsing, I have to get several cavities filled tomorrow. (it's genetic 🙄)
It's been nearly 4 years since I've had some filled and I'm not sure what to expect. They want to administer nitrous oxide along with the shot. I haven't had nitrous oxide in 8 years- anyone have any recent experience? Thanks ladies!
