Ouch! Hope that you got this fixed and could enjoy vacation....
for anyone else who may need a dentist, I needed some emergency repairs and went to a dentist in Lake Buena Vista next to the post office and the Eckerds just off Palm Parkway.
Excellent service, very high tech. (but unfortnately out of my insurance coverage range, and they weren't pleased to hear me whispering in german with the poor cast member from Germany about the prices as she decided what to do!)
If you do need a dentist, I do recommend this place - after all, on vacation you don't want to hunt around and take a risk with a poor quality dentist!!
