Would bioclear or veneers be better suited for what I'm trying to achieve with my teeth? (photo)

From your photoshopped picture, it looks like your desired end result is a different tooth shape than what you currently have. Either Bioclear bonding or porcelain veneers will be able to achieve this. The porcelain veneers will resist stain more so if you drink coffee, tea or red wine this would be a better choice. In the past, bonding was seen as a less invasive treatment, but modern porcelains can be made as thin as a contact lens so this is no longer an issue. Bonding will be less expensive initially, but will need to be replaced every few years as the bonding absorbs stain.
