"Twilight" dentistry in Mexico?

Yup, you are definitely not the only one with that phobia. My DH is ( or was ) one of them, that is, before he became my guinea pig for school :B

Dental pain can bring the biggest, baddest biker to his knees. It is just a different pain than any other, and really cannot be described.

I'm sure you will work it out ( hopefully without any iv's ) and it will go very well.

Best of luck and travel safe!
