Hi, I do the prep the same day as you get your temporary veneers. The wax-up and smile design is done before any prepping is done. It's difficult to prep/remove tooth structure when you haven't designed the case/final design. Hope this helps! Bests! Dr. Marty W. Lindahl
Options vary on your desired outcome: 1. Laser frenectomy and ortho treatment. This is conservative and takes the longest treatment time. 2. Laser frenectomy, whitening, and minimum/no prep veneers depending on the way your teeth come together. It looks like you also have other spaces between your teeth that need to be addressed. Maybe 4 veneers could work nice from the pictures you presented. Treatment 2-3 appointments. Good Luck! Dr. Marty W. Lindahl
