I saw Dr. Kareth about five years ago for a routine cleaning. I was told I had a cavity in my molar that needed to be filled. When I got home and looked at it, I notice that it seemed like a very large filling. It touched all the points on my tooth and took up nearly the whole surface. I was very surprised since it was the only filling I'd ever had to have and I was not experiencing any discomfort from the tooth prior to my appointment.
The dentist I saw the next time (not Dr. Kareth) asked about the filling, as it's my only one and the rest of my teeth are in great condition. He didn't explicitly say I'd been taken advantage of, but he said that the more surfaces the filling touches, the more a dentist charges an insurance company for it. It seemed like his gentle way of letting my know what happened.
Now, about 5 years later, part of the filling fell out and the tooth has cracked away because so little of the original structure was left. It's probably going to require a crown, which is just crazy as I'm only 27 and it's the only cavity I've ever had in my life. I can't believe I had such a severe cavity in that tooth that his treatment was justified.
I can't be sure Dr. Kareth was unethical in my treatment, but I'm suspicious of what happened. It just doesn't add up.
