Digital Smile Design: see your new smile before treatment starts

Deciding to change your smile is a big step, and it is natural to want to know what the result might look like before anything is done. Digital smile design is an approach that uses photographs, video and planning software to help you and your dentist picture the outcome together, before treatment begins. It is not a treatment in itself, but a way of planning one more clearly.

What is digital smile design?

Traditionally, cosmetic dental work was planned mainly on models of the teeth, guided by the dentist's experience. Digital smile design adds your face to the picture. Your dentist records a set of photographs and short video clips of you talking and smiling, often alongside a 3D scan of your teeth. These are brought together in planning software, where proposed changes can be sketched out and adjusted on screen.

The approach can help plan many kinds of treatment, including veneers, crowns, tooth-coloured bonding, orthodontics and, in some cases, gum reshaping, often in combination.

Designing around your face, not just your teeth

A beautiful smile is not simply a row of white, even teeth. It needs to suit the person wearing it. When planning, dentists look at how your teeth relate to your face as a whole:

• The facial midline, and whether your front teeth are centred with it.
• The smile line, meaning how the edges of your upper teeth follow the curve of your lower lip.
• How much tooth and gum show when your lips are relaxed, when you speak and when you smile broadly.
• The proportions of each tooth, its width compared with its length, and how the teeth step gently back from the centre.
• Shape, surface texture and shade, so the result looks natural for your age and features.

Guidelines about proportion can be a useful starting point, and you may hear the golden ratio mentioned. They are not rules, though. Faces are individual, and good planning takes that into account.

Trying it on: mock-ups and trial smiles

One of the most helpful steps is moving from the screen to your mouth. From the digital plan, a model of the proposed teeth can be made and used to create a mock-up: a temporary, tooth-coloured material placed over your own teeth, usually without any drilling. It lets you see and feel the proposed shape in real life.

With a mock-up in place, you can look in a mirror, smile, talk and take photographs. It is a good moment to ask questions and give honest feedback. Perhaps the teeth feel a little long, or you would prefer a softer shape. Changes at this stage are simple compared with changes after treatment.

Seeing a proposed smile on your own face, in your own mirror, is often more useful than any description.

A shared plan

Because the design is visual, it is easier for everyone involved to agree on the goal. You can see what is being proposed and why. Where more than one clinician or a dental laboratory is involved, they can all work from the same plan, which helps keep treatment consistent from start to finish.

Keeping expectations realistic

A digital design is a plan and a communication tool, not a guarantee. The final result depends on many things, including the health of your teeth and gums, your bite, the materials used and how your mouth heals. Some changes that look simple on screen may not be advisable once the health and function of your teeth are taken into account, and a good plan puts those first.

It is also worth remembering that some cosmetic treatments, such as certain types of veneer, involve removing a layer of enamel and cannot be undone. Take your time, ask about the alternatives, and make sure you understand the benefits and drawbacks of each option.
