Wow! You weren't kidding!
I had to wait over 2.5 hrs before the procedure!
That on top of the fact that they told me not to eat for 6 hrs before meant I was fasting till 5pm, which actually led me to faint while waiting for an uber afterwards.
But b"h the extraction itself went pretty fast and smoothly. Hopefully will heal the same way.
I would go back to him (and I will for other 2 teeth), but I recommend asking for first appointment so no delays...
