Patient has a conspicuous front crown. She was interested in replacing it. She also has peg laterals (small side front teeth). If you are ever considering work on your front teeth, it is advisable to have all the teeth in question treated at once as you can match the shape and color together. The peg laterals did not bother her too much, but she was curious to see how they could be improved. Preview is an option where a mold is created off an idealized wax rendering of your teeth. A provisional temporary is then created utilizing that mold. In essence, you get to preview your results without committing to treatment. At the end of the visit the provisional is removed so your mouth remains unaltered. This direct visualization in your mouth allows you to make an informed decision.
