Teeth Whitening
(Medical procedures and examinations)
This topic will help you learn about teeth whitening and how to prepare for it.
What is teeth whitening?
- Teeth whitening is a non-surgical procedure used to improve the color of teeth by removing surface and deep stains. This procedure relies on bleaching agents that usually contain hydrogen peroxide or carbamide peroxide, which work by breaking down stains and lightening the tooth color without affecting its structure.
- What are the types and forms of teeth whitening?
1. In-office teeth whitening:
Performed under the supervision of a dentist.:
- High concentrations of the bleaching agent are used, sometimes with laser or LED light, to speed up the results.
- Usually provides quick and effective results, often after one session.
- Suitable for severe discoloration.
2. At-home teeth whitening (under dental supervision):
Involves using custom-made trays filled with bleaching gel and worn at home for several days.
Results are gradual but safe.
3. Over-the-counter whitening products (without prescription):
- Whitening strips:
- Contain a bleaching agent (usually hydrogen peroxide) and are applied directly to the teeth.
Typically used once or twice daily for 30 minutes, for 1–2 weeks.
Relatively effective for teeth with surface stains.
