Sometimes much of what I do as a cosmetic dentist is replacing or redoing cases done by other, maybe less experienced dentists.
This is an example of a material that was supposedly a minimal, we call it minimal prep. They didn't really remove much tooth structure in an effort to be conservative.
The result, however, wasn't very durable and the patient was even told prior to treatment not to expect this to last maybe more than maybe five or six years.
My question to her was, Why did you say yes? An investment such as this should last a lot more than five or six years, and we routinely have patients, I've got some cases that look the same today 20 years later, as they did the day that we delivered them.
