Summary
Teeth whitening is possible during orthodontic treatment with braces. This in-office procedure effectively whitens teeth without compromising aesthetics, satisfying patient desires for a straighter, brighter smile simultaneously.
Area of Science:
- Dental Aesthetics
- Orthodontics
- Tooth Whitening
Background:
- Patients undergoing orthodontic treatment often desire whiter teeth alongside alignment.
- Historically, in-office bleaching with braces was thought to cause enamel spots.
- Advancements in understanding peroxide diffusion challenge this previous notion.
Observation:
- In-office bleaching treatments using 35% hydrogen peroxide were performed on patients with fixed orthodontic braces.
- Treatments involved two to three 40-minute sessions.
- The study aimed to assess the efficacy and esthetic outcomes of simultaneous treatment.
Findings:
- In-office bleaching is effective and feasible with orthodontic brackets in place.
- Successful tooth whitening was achieved despite the presence of brackets.
- No esthetic loss was observed, meeting patient expectations for aligned and whitened teeth.
Implications:
- Simultaneous orthodontic treatment and in-office bleaching can reduce overall treatment time.
- This combined approach can enhance patient motivation and adherence to orthodontic therapy.
- Patients can achieve a straighter, whiter, and functional smile more efficiently.
