Why is my smile so bad? Front teeth too wide? I had 6 veneers through Bioclear done last year. (Photos)

Thank you for your question and posting the pictures. 
The veneers you have now are too big and bulky for your face and smile. They also look very opaque and over contoured. In order to fix this, they need to be removed and redone. The veneers should be made to fit your smile and balanced with the natural symmetry of your face.`
I would seek an expert cosmetic dentist in your area who's work you like and has good reviews. 

The veneers probably look better than your previous but could possibly be improved as you have noticed something is not just right.   Cosmetics is in the eye of the beholder ie the dentist but more importantly the patient!In dentistry we call the "Golden Proportions" a very helpful tool in developing the proper length to width proportions of the teeth in the smile line.  I also think your teeth should be more squared.  If you are considering replacing, have them adjust those veneers or fabricate ideal temporary veneers prior to making the final veneers.  You need to approve and wear the new shape so then they can copy that result.Hope this helps, every dentist is different so finding the right one that has an eye for cosmetics and symmetry is not always easy.  Word of mouth referrals and personal references from happy patients is what it is all about in dental marketing.
