For this case we used the ABC technique of Aligning, Brightening, and Composite bonding. This technique takes longer than veneers but meant we didn't drill any enamel, or even need any injections!
We began with 6 months of straightening the teeth. This was followed up by whitening. You can see the teeth are quite narrow so straightening alone would not give us the best result. Wider front teeth look better. Once the straightening was complete we used composite bonding to add material and add width to each tooth.
