I have three words . Yuck, sheesh, and oww!
Yuck: They put DISGUSTING tasting liquid in my mouth.
Sheesh: They Put so much different tools, liquid, and special glue in my mouth. And did I mention that some of these things tasted DISGUSTING!
Oww: They put these things in to pull my cheeks away from my teeth and it hurt. They were also glueing metal to my teeth and stuff, and I'm guessing that you can imagine how that felt.
