"I'm not threatening. conceptually nothing is wrong with it. but if you're like me, I have a mouth full of glue and crown. porcelal crowns on my back molar, which warm and cold (especially) and a few pre-species, some binding. I sat a few hours with a friend on a hot summer day outside and it took me all the visit to eat that was so cold and hard, I thought I would break my teeth. I know that's not everyone's problem, but everyone who has everyone who has dental work is my warning. just say it."
