17 porcelain veneers and I think the front 2 teeth are too big. I think they look like Bugs Bunny. (Photo0

If your prepless veneers make your teeth look larger, consider slight reshaping. For future procedures, request a diagnostic wax-up to preview the outcome. For a more natural look, you might need to replace the veneers with some tooth preparation involved.

Unfortunately, there are severe limitations to the cosmetics results of fully prepless veneers. The major being the final thickness and fullness of these veneers tend to seem too prominent and large. The only solution I can see here is having the veneers redone with proper planning and smile design by an experienced cosmetic dentist and will likely have some mild-moderate preparation for a proper aesthetic result.

When getting large cosmetic dental procedures, it is important to get a pre operative diagnostic wax up. By doing this, you will be able to see what your final teeth will look like before ever getting in the chair. This is my personal opinion and not a diagnosis.

It is for sure that the teeth are bigger than the natural teeth as it is prepless veneer. You will need to have the teeth shaved down slighltly if you would like to have them smaller.
