During your initial smile design consultation, our expert cosmetic dentist will first seek to understand the look you really want. They will go over all of the factors which influence it, specific to your characteristics. This means you work with the dentist to design your perfect smile. Then, once agreed, they will create your new smile with temporary solutions (wax up models, temporary veneers, temporary crowns). Which means you can now try the proposed design in your own mouth. These temporaries can be modified to your exact requirements and the changes will be duplicated in the finished restorations.
So, the final decision is still yours and only when you are happy with your new smile does the permanent treatment start.
