Would I benefit from having my porcelain veneers replaced? (photos)

It's truly disappointing to hear that your experience with porcelain veneers has not met your expectations, especially with such an important event like your wedding approaching. Veneers should enhance your smile and feel natural, not cause discomfort or dissatisfaction. Given the issues you’ve described — gaps, poor gum aesthetics, and a bulky appearance — it would be wise to consider replacing them.

In Miami, where you have access to numerous specialized cosmetic dental clinics, it’s crucial to seek out a provider with a strong track record in porcelain veneer placement. Look for a clinic that not only has extensive experience but also positive patient reviews, particularly concerning the aesthetics and comfort of their veneers. Before proceeding with such a significant investment, consult with a few well-regarded cosmetic dentists to discuss your concerns and see their previous work. This step will help ensure you achieve the beautiful, natural-looking results you desire for your wedding.

It looks like you have chronic inflamation around the gingival margins.
You need to look at a relaxed natural smile to really understand how the lips and soft tissues interact with veneers.
If your only issue is the space a retainer could close the space.
Do you hit the front teeth first when you close because that can cause anterior spaces.
I feel you may not like the opaqueness of the teeth.
Ideally, maxillary expansion would have been done prior to the cosmetics, but if not done I would have built the bicuspids out to create a 10 tooth smile. You did 10 teeth but till have a six tooth smile.
