One lady I knew had gone to a Comfort Dental / Bright Now (can't remember which) because she kept suffering from achey teeth. Dr. did a root canal on 3 teeth. She kept suffering from aches and pressures so the Dr took 2 teeth out a few months after having the root canal done. 4 wks later she's still having symptoms so she comes to our office and we ended up diagnosing an untreated sinus infection as the problem. Homegirl lost 2 teeth because a Dr was half assing his job.
I've temped at offices where pts go in with the slightest pain and its an automatic root canal and crown. I've seen Drs drill on the wrong teeth, almost take the wrong teeth out etc.
One of the worst cases I've ever seen though was this 16 yr old boy who has had braces on since he was 9. Kid had a severe open bite and needed surgery to fix it.
Apparently, they charged her insurance for the procedure and told her the son had a weird jaw disorder that caused everything to relapse and that's why his teeth still weren't straight and jaw all messed up. Dr gave the parent the number to his lawyers and told her to sue the fukk out of them for malpractice / negligence.
If you guys ever think a dentist is bullshytting you don't be afraid to go another office for a second opinion. It never hurts to be safe. Some Drs treat things very aggressively while others more conservatively.
