What is a smile line simulation for veneers?
It is a digital design step that maps the edges of the front teeth to your lip line and facial photos before any veneer is made.
Smile design software overlays your facial photos, smile videos, and tooth scans to draw a proposed smile line. The dentist and lab use it to plan tooth length and proportion that follow the lower lip when you smile.
From screen to mouth
The simulation is usually shown to you as edited photos or a 3D preview, then converted into a wax-up and mock-up you can try on the teeth. That chain keeps the on-screen plan and the final ceramic connected instead of leaving the outcome to guesswork.
A simulation is a planning aid, not a promise — lips, gums, and muscle movement differ for each person, so the real result can deviate from the render. Treat it as a conversation tool and consult your dentist on what is achievable for your anatomy.
