Professionelles Zahnbleaching: Vergleich von In-Office, At-Home und OTC-Optionen

Dental bleaching lightens tooth color by oxidizing pigmented compounds using hydrogen peroxide or carbamide peroxide. A dentist should evaluate oral health before any whitening treatment.

Methods

1. In-Office Bleaching

High-concentration gel applied by a dentist, often activated by light/heat. Provides rapid, dramatic results in 1-2 visits.

2. At-Home Custom Trays

Dentist-fabricated trays with lower-concentration gel worn daily for 1-2 weeks. Offers control and gradual whitening.

3. Over-the-Counter (OTC) Products

Strips, gels, toothpastes with lower peroxide levels. Less potent, results are gradual and variable.

4. Laser/Light-Assisted Bleaching

Light energy accelerates the bleaching reaction. Can be done in-office or with at-home devices.

Considerations

• Sensitivity and gum irritation are common but usually transient
• Restorations (crowns, fillings) do not whiten
• Results vary based on stain type (extrinsic vs. intrinsic) and tooth structure

Consult your dentist to choose the safest, most effective option for you.
