Is your dentist focusing on the wrong thing for your smile?
A new study from the University Of Gothenburg has revealed that even tooth colour may be more important to patients than simply having a whiter smile — a finding that could transform how dentists plan cosmetic treatments and manage patient expectations.
Researchers asked participants to rate their satisfaction with their own tooth colour and to evaluate unevenness, which referred to deviant colour on part of a tooth or visible spots.
Key findings of the study
The study found that 77% of participants were satisfied with their tooth colour, with no major differences between gender or age groups. However, those who noticed a deviant colour on a part of a tooth were less satisfied overall and reported wanting corrective treatment.
- 22% of women vs. 13% of men had tried tooth whitening.
- Only 9% of those with deviant tooth colour had undergone corrective treatment.
- 52% said they were interested in seeking such treatment in the future.
Laura Ståhl, PhD student at the Institute Of Odontology at the University Of Gothenburg and the study’s first author, emphasized the importance of listening to patients' concerns:
“What we found is that participants notice uneven tooth colour and perceive it negatively. Those more satisfied with their own tooth colour placed greater importance on the colour of teeth, both their own and others’,” she said.
Why this matters for dentists and patients
Experts say the findings could prompt dental professionals to prioritize shade harmony and colour uniformity over maximum whiteness during treatment planning. Patients should also be educated about available solutions, such as targeted whitening, composite bonding, or veneers, that can correct single-tooth discolouration without over-bleaching.

Nina Sabel, associate professor at the Institute Of Odontology and paediatric dentist, added:
“Different colour deviations have different causes and require different treatment types. Dental professionals are knowledgeable about the risks and can ensure bleaching is done safely, with low hydrogen peroxide concentrations, to minimize side effects.”
A balanced approach to smile aesthetics
The study highlights a growing shift toward natural, authentic smiles rather than overly whitened teeth. Dentistry experts warn that over-bleaching can damage enamel and create an unnatural look that cannot be reversed.
Instead, the focus should be on restoring balance and confidence, allowing patients to smile, laugh, and express themselves freely.
