Based on the photos you provided, your current veneers look generally good. In my professional opinion, they do not appear excessively bulbous, and I have seen many veneer cases that look considerably thicker. Overall, your veneers appear fairly well proportioned. That said, I can understand what you are noticing. There is a subtle hint of additional fullness, particularly when compared with the appearance of your natural teeth. This does not necessarily mean that the veneers are poorly designed, but it may reflect one of the aesthetic trade-offs involved in conservative veneer treatment. When placing veneers, cosmetic dentists often try to preserve as much of the natural tooth structure as possible. With no-prep or minimal-prep veneers, much of the underlying tooth remains intact. The veneer then has to be placed over that existing tooth structure, which can create some additional thickness or fullness. This is an important consideration when choosing between minimal preparation and more traditional preparation. Preserving more natural tooth structure can be beneficial, but it may limit how thin or flat the final veneers can appear. In some cases, achieving a slimmer appearance requires removing a little more tooth structure underneath so the veneers have enough space to maintain proper strength and contour. If you feel that your current veneers are acceptable and you can adjust to their appearance, they seem to be a reasonable result based on the photos. If you remain significantly unhappy and want them to look less bulbous, discuss your concerns with your dentist before making any changes. Depending on the design, minor recontouring and polishing may provide a small improvement, but these procedures cannot always make veneers substantially thinner. If replacement becomes necessary, your dentist may need to prepare the underlying teeth slightly more to create room for veneers with a flatter, less prominent contour. Before proceeding, it is important to review the desired shape carefully using photographs, digital previews, or temporary veneers. Be specific about how much fullness you want to reduce while also maintaining a natural appearance, proper function, and adequate veneer thickness. It may also be helpful to obtain a second opinion from an experienced cosmetic dentist, especially if you are considering replacing otherwise healthy veneers. Look for a dentist whose before-and-after cases consistently show the tooth proportions, facial contours, and level of naturalness you prefer. Overall, your veneers do not appear excessively bulbous in the photos. They look fairly good, with only a subtle fullness that may be related to the conservative approach used to preserve your natural tooth structure. The best next step is to discuss whether any limited cosmetic adjustment is possible and whether the potential improvement would justify further treatment.
