Smile planning
Smile planning starts with what you would like to change and whether treatment is needed.
SHORT ANSWER
Smile planning starts with what you would like to change and whether treatment is needed. The dentist assesses how your teeth, gums, lips, face and bite work together.
Start with the complaint, not the template: One person may dislike tooth colour; another may be concerned about worn edges, spacing, old crowns or gum levels. The same “smile makeover” label can therefore lead to completely different treatment plans.

Start with the complaint, not the template
One person may dislike tooth colour; another may be concerned about worn edges, spacing, old crowns or gum levels. The same “smile makeover” label can therefore lead to completely different treatment plans.
What may be assessed
- tooth proportions and visible tooth display;
- colour and surface characteristics;
- gum health and gingival levels;
- tooth position and spacing;
- lip movement and smile line;
- bite and functional contacts;
- existing restorations and available enamel.
Digital planning can support communication
Photographs, scans and digital mock-ups can help discuss proposed changes, but they should not be presented as an exact preview of the final biological result.
The most important design decision can be to do less
Whitening, minor bonding, replacement of a defective restoration or no restorative treatment at all may be more appropriate than preparing multiple healthy teeth. Aesthetic planning should preserve options for the future whenever possible.
Smile design is not a licence to treat every visible tooth
A coherent plan can include no treatment on some teeth, whitening on others, limited bonding on a few areas and replacement of only the restorations that genuinely need it. Treating every visible tooth simply because it appears in the smile zone is not inherently more aesthetic.
Face, lips and gums change how teeth are perceived
The same tooth proportions can look different depending on lip mobility, incisal display, gingival levels and facial symmetry. This is why a close-up image of teeth alone is not enough for aesthetic planning.
Function still matters
Aesthetic changes alter contacts and guidance. The bite needs to be considered so that thin ceramic edges or composite additions are not placed into avoidable overload.
Trial and communication
Photography, digital scans, mock-ups and provisional restorations can make the discussion more concrete. Their role is to help patient and dentist communicate—not to promise an exact visual result.
Questions to ask
- Which parts of my smile can change without drilling healthy teeth?
- Are gum treatment or orthodontics relevant before restorative work?
- Which changes are reversible and which are not?
- How many teeth genuinely need treatment?
A smile plan can include several different treatments—or none
One of the strengths of proper planning is that it separates the visual goal from the material used to achieve it. A patient may need whitening only, orthodontic alignment, repair of two edges, replacement of old crowns, periodontal treatment before restorative work, or a combination. The plan should not be reverse-engineered to justify a preselected package.
Symmetry is not the same as naturalness
Natural teeth contain small variations in shape, texture and translucency. Excessive pursuit of perfect symmetry can make a smile look artificial. The aim is proportion and coherence with the face, not mathematical uniformity.
Maintenance belongs in the design stage
A restoration that looks attractive on the day of fitting but is difficult to clean or repair is not a good long-term design. Margins, contact areas, interdental access and bite all need to be considered before the cosmetic result is finalised.
