I had 24 zirconium crowns, a few root canals, and an extraction. I can honestly say for me the entire treatment was pain-free, not even a slight ache after the process which surprised me as you expect some level of soreness after, but I had none at all.
I did have the IV sedation option for the preparation day and for me, it was worth it as I do have a dental phobia. The price was very competitive, and my price did not change once I arrived in Turkey, they are true to their word in the price they give you.
