Procedure went near perfect - Textbook, I might add!

Procedure went near perfect - Textbook, I might add! Insurance covered pretty much all of it - which I was very thankful for! Dr Cheng did a great job and was a super nice guy! I remember telling him I was scared about the wisdom teeth procedure and as he was reassuring me, Darkness! The anesthesia hit- 45 minutes later, I awoke with gauze in my mouth. The recovery took about 5 days until pain and soreness dissipated to minor levels but overall, I was able to handle the pain with Ibuprofen after 2 days. It really wasn't that bad. Just follow all the instructions they give you and you'll do fine. Being new to the area, I was really worried about finding a skilled oral surgeon who could maximize my insurance benefits. Luckily, I got both! You're in really great hands with Dr Cheng!
