I love using the xtip when I am only needing to numb a single lower molar.  Patients don't feel a thing and it gives me a way to re-numb the area as needed.  We use it for making Cerec crowns.  Dr  Kit created this, and it is brilliant.

 I went to Kit Weathers' Endo Root Camp a few years ago after referring all root canals for many years.  Kit has an excellent step by step system that works really well.  Since taking Kit's course, I've done the best root canals of my career--and you can, too.  As a bonus, Kit does his weekly "Root Tips of the Week" videos that keep you up to date with the latest helpful tips for success in endo.  And don't be surprised if you learn some magic tricks, as well, as Kit is famous for his magic!  By the way, Kit is also famous as the inventor of the X-Tip system for intra-osseous local anesthesia.  We are very happy to have Dr. Kit Weathers as a distinguished member of The Dental Comfort Academy.
