What is Digital Smile Design?

Digital Smile Design (DSD) is a planning method that uses facial photos, video and intraoral scans to design tooth shape, length and gum line in relation to your face before any treatment. At Gangnam One Day Dental Clinic, DSD has been used since 2015 to plan veneers, crowns and smile makeovers, so you can review and adjust the design first.

How Digital Smile Design works

DSD starts with records rather than drilling. We take full-face and close-up photos, a short smile video and an intraoral scan. The design is drawn over your face, so tooth length, width and midline follow your lips, eyes and facial midline, not just the teeth in isolation.

The digital design can then be turned into a trial mock-up in tooth-coloured material placed over your teeth. You see and feel the proposed shape before any enamel is prepared. Changes to length, edge shape or colour are made at this stage, when they cost nothing to adjust.

  • Smile line and lip support analysed together
  • Tooth width-to-length proportions measured
  • Gum line symmetry checked before cosmetic work
  • Bite checked so the new shape works when you chew

What DSD is used to plan

DSD is a planning step, not a treatment on its own. It is most often used before porcelain veneers and full smile makeovers, where several teeth must match in shape and shade.

It also shows when the gum line, not the teeth, is the main issue. In that case the plan may include gum contouring before veneers, or orthodontic movement first, so that restorations are not used to hide a positioning problem.

  • Veneers (prep and no-prep) and all-ceramic crowns
  • Whitening target shade before restorations
  • Gum contouring and gummy smile assessment
  • Combined orthodontic and cosmetic plans

From design to finished teeth in one building

The approved design is passed to Oneday Lab, our in-house dental lab on the 14th floor of the Startplex building, opened in 2022. The lab uses CAD/CAM milling, and temporary to final prosthetics can be made in one day when the case allows.

Before final cementation, the bite is checked with T-Scan Novus digital occlusion analysis, which records bite-force detail to 0.01 mm. A smile that looks right but overloads one tooth is a common reason cosmetic work chips, so the bite is part of the design.

Things to know before you decide

  • A digital design is a plan, not a promise of the exact result: final shade and translucency can differ slightly from a screen image.
  • Gum disease, active decay or a heavy grinding habit must be treated or managed before cosmetic work.
  • Some designs are only possible with orthodontic movement or gum surgery first, which adds time.
  • If your expectations differ from what your teeth and face allow, the dentist will tell you before treatment starts.

FAQ

Digital Smile Design: common questions

Can I see my new smile before treatment starts?
Usually yes. After the digital design, a trial mock-up in tooth-coloured material can often be placed over your teeth so you can see the shape in a mirror and in photos. It is removed afterwards. Whether a mock-up is possible depends on your tooth position and is confirmed at examination.
Is Digital Smile Design a separate treatment?
No. DSD is the planning stage for treatments such as veneers, crowns, whitening and gum contouring. It decides the shape, length and shade, and the chosen treatment then follows the plan. The design files are also used by our in-house lab to make the restorations.
Can I choose the colour and shape of my teeth?
Yes, within limits set by your face, bite and gum line. You can discuss how white, how long and how rounded or square you want the teeth. The dentist explains when a request would look unnatural or put the bite at risk, and the mock-up lets you compare options.
How long does the DSD process take?
Records and examination are usually done in the first visit. The design and mock-up typically take one or two visits. If you are travelling, sending photos and X-rays on WhatsApp beforehand helps the dentist prepare, so more can be done during a short stay.
Do I need DSD for just one tooth?
Not always. For a single crown or small bonding repair, standard shade matching may be enough. DSD is most useful when several front teeth are being changed, or when the gum line, smile line or facial midline needs to be considered together.
How much does Digital Smile Design cost?
The cost depends on the scope of diagnosis and the treatment that follows, such as the number of veneers or crowns. An estimate is given after the dentist reviews your photos and X-rays on WhatsApp, and confirmed after examination in Gangnam.
