Cosmetic Dentistry Is Aesthetic Judgement Applied To Restoring Teeth
It's a simple formula yet hard to deliver. WHY? Because there is no standard for a perfect smile. All the rules for designing smiles are at the end formulaic, which for the most part result in predictable and plastic results.
I would say the #1 reason patients hesitate to initiate a cosmetic dental procedure, aside from cost, is absence of a guarantee that they will like the final results.
In my practice I overcome this by making multiple trial temporaries and the agreement that a short term delay is better than living a life-time with less than perfect results. So when in doubt, I make yet another trial run of the final result, have my patient live with them for a week or two, before making a commitment to the final design.
