A smile design treats the smile as a whole rather than fixing teeth one at a time. The length and width of the teeth, their proportion to each other, whether the midline lines up with your face, how much gum shows when you smile — all of it is assessed together.
That is why two patients having the same procedure do not end up looking alike — and should not.
The mock-up: the step that matters most
Before anything permanent is done, the planned design is tried in your mouth. Applied over your teeth in a temporary material, this mock-up lets you look in the mirror, talk and smile with the new shape.
The value of this stage is simple: asking for changes here costs nothing and is easy. “A little shorter”, “not such sharp corners”, “it sits oddly against my upper lip” — all of that can be dealt with at this point. Once the permanent restorations are in, the same change is far harder.
Be wary of a plan that skips the mock-up. If the result is never shown in advance, you lose the chance to correct anything you do not like.
How the days run
- Day one — examination, impressions and preparation
- Day two — no clinic visit; the laboratory works while you rest
- Day three — the mock-up, any adjustments, then fitting
- Day four — final check and aftercare advice
The treatment is spread over three days, a four-night stay is planned, and the main session at the clinic takes around two hours.
How long does the result last?
Depending on the material, a service life of ten to fifteen years is given. What really determines it is daily care and regular check-ups; if you grind your teeth, wearing a night guard makes a clear difference to how long the result holds.
What is actually assessed
The design starts with the face, not the teeth. Is the midline — the line between the two front teeth — aligned with the midline of the face? A small discrepancy between those two is one of the most common reasons a smile looks subtly off.
The second measure is the smile line: the curve traced by the edges of the upper teeth should follow the curve of the lower lip. Teeth ending in a flat line look artificial; in a natural smile the central teeth are slightly longer than those beside them.
Third is the gum level. If a lot of gum shows when you smile, adjusting the gum line can give a better result than lengthening the teeth. That is a separate procedure, and it should be discussed as part of the design.
What digital design adds
A digital design can be prepared from your photographs and an intra-oral scan. Its value is that the proposed change can be seen on your own face — a concrete image instead of a vague “it will look neater”.
But a digital design is a simulation, not a guarantee. The final result is settled by the mock-up in your mouth; a screen image and how something feels in your mouth are not the same thing. The soundest process uses both: discuss it on screen, then try it in the mouth.
What you need to say
Your dentist can see your mouth but not your expectation. So describe what you want as concretely as you can. “Make it nicer” is not a goal; “I want my front teeth slightly longer, but not an exaggerated white” is.
Bringing a photograph of a smile you like helps — as long as you remember it belongs to another face. The same tooth shape reads differently on different features; the photo is a way of communicating your taste, not a template to copy.
If you see the mock-up and do not like it, say so. Approving it to avoid offending the dentist means accepting a result that is far harder to change later. The mock-up stage exists precisely for this.
Can I change my mind during the design stage?
Yes — that is exactly what the mock-up stage is for. Work done in a temporary material comes off easily and can be reshaped. Once the permanent restorations are placed, that flexibility is gone, so raise anything you are unsure about during the mock-up.
My teeth look very small — can they be lengthened?
Usually yes, but the cause matters first. The teeth may have shortened through wear, or they may be a normal length with the gum covering too much of them. The first calls for restoration, the second for adjusting the gum line — two different procedures.
Is a smile design the same as a Hollywood Smile?
A smile design is an approach to planning; a Hollywood Smile is a description of an outcome. The design process may end in whitening, cosmetic bonding or veneers — which one depends on the state of your teeth. So every Hollywood Smile involves a design, but not every design ends in veneers.
