We had one patient the other day came in complaining that #3 was tender. She was missing several teeth. We had been talking to her about bridges or implants to replace those teeth, and she wasn't really interested. When she came in with #3 symptoms this week, we used the T-Scan, and showed her why that tooth was sensitive. Turned out it was the only posterior tooth touching, taking all the forces. She saw that, understood that, and we sold the case. She committed to her treatment that day.
