To visualize how the final result could be we perform a mock up to simulate with an acrylic template the final situation and photos of the patient are taken. This is our communication tool, either from the patient to the dentist as well as from the dentist to the dental technician. Once the patient agrees, the teeth are, if necessary, very little prepped and the dental technician uses the mock-up as the template for the veneers. In the majority of the cases we avoid prepping the teeth and create a smile rehab with so called Non-prep veneers, where the tooth substance remains completely unprepped. Before the bonding of the veneers in the majority of the cases the teeth need to be bleached since the veneers are very thin and the underlying tooth substances might have a darker shade and might shine through.
