Are these crowns too big or not? (Photo)

Question

The dentist created a plastic model of crowns for my upper teeth, which I need to use to decide whether to install zirconia crowns. I'm aware that due to the large gaps between my front teeth, the crowns will need to be larger than my natural teeth. However, I am concerned that they may be too big. Do you think the work is satisfactory? I need help making this decision.

Deciding on the size and shape of crowns is an important part of achieving a smile you're happy with, and I'm here to provide you with professional insight.
Based on the images, I can see that the temporary crowns (or wax-up/mock-up) have been designed to close the gaps between your natural teeth. It's true that in cases like yours, where there are significant spaces to correct, the new crowns may need to be slightly larger than your original teeth to achieve proper aesthetics and functionality. That being said, there are a few key considerations to address:
1. Proportions and Natural Appearance:The size of the crowns should blend harmoniously with the rest of your teeth and facial features. Larger crowns can sometimes look less natural if not carefully proportioned. In this case, your dentist likely made them slightly larger to address the gaps. However, it's important that you feel they look balanced and natural when you smile.
2. Functionality:The temporary crowns are a great tool for testing. Pay attention to how they feel when you speak, bite, and chew. If you notice discomfort, issues with speech, or an unnatural sensation, adjustments may be needed. Crowns that are too large can also create functional issues over time.
3. Smile Design:A comprehensive smile design often considers facial symmetry, lip line, and tooth proportions. If you’re unsure about the aesthetics, ask your dentist to explain the reasoning behind the size and shape of the crowns and how they fit into the overall design. You may also inquire if minor refinements can be made to meet your preferences.
4. Final Zirconia Crowns:Keep in mind that the final zirconia crowns will have a more refined appearance than the temporary plastic mock-ups. Zirconia crowns are crafted with precision to mimic the natural translucency and texture of enamel, and adjustments can be made before they are finalized.
My Recommendations:Share your feedback and concerns with your dentist. Dentists with expertise in smile design are accustomed to making refinements based on patient input.If you're uncertain about the current mock-up, ask if any adjustments can be made to the shape or size before finalizing the zirconia crowns.
Consider bringing photos of smiles or teeth shapes you like to help communicate your aesthetic goals.
Ultimately, your comfort and satisfaction with the final result are paramount. Your dentist should guide you through this process collaboratively to ensure you achieve a smile that looks and feels right for you. 
Best regards, Dr. Miller Vieira Paula.
