From White to Even: How Tooth Color Consistency Shapes Patient Satisfaction

From White to Even: How Tooth Color Consistency Shapes Patient Satisfaction

A recent study from the University of Gothenburg reveals that patients care more about the consistency of tooth color than simply having a bright white smile. Many individuals are dissatisfied if parts of their teeth show different shades, even subtly.

🔍 Key Findings

• Patient Satisfaction: 77% of participants were generally satisfied with the overall color of their teeth, with no significant differences based on age or gender.

• Concern About Tooth Shade: Those noticing inconsistent coloring were less satisfied and more likely to focus on correcting it.

• Whitening Treatments: 22% of women and 13% of men had tried teeth whitening. Among participants who detected color inconsistencies, 9% had undergone corrective treatment, while 52% expressed interest in doing so.

💬 Expert Insight

Laura Ståhl, a PhD student at the University of Gothenburg’s Institute of Odontology and lead author of the study, emphasized that participants noticed and negatively perceived differences in tooth color. She highlighted the importance of listening to patient perspectives—especially younger generations—and recognizing that oral health impacts both physical well-being and confidence in one’s smile.

🖼️ Aesthetic Evaluation

Participants were also asked to rate photographs of teeth with and without visible color variations. Among those perceiving inconsistent tooth shades, 90% identified color differences as the primary issue, though the extent and intensity of the discoloration also influenced perceptions.

⚠️ Professional Recommendations

Professor Nina Sabel, a dentist and faculty member at the University of Gothenburg, stressed that tooth color is an important aspect of appearance. She advised careful management of whitening treatments, using low-concentration hydrogen peroxide and avoiding over-whitening to minimize side effects such as gum irritation.
