Teeth whitening methods and cost information
Teeth whitening is a procedure to improve tooth color. Common types include in-office whitening (e.g., laser, light-activated) and custom tray home whitening. Suitable methods and costs vary based on tooth and gum condition. Currently, it is out-of-pocket and not covered by National Health Insurance. The following is neutral information; suitability and precautions should be evaluated by a dentist, not medical advice.
Differences between in-office and at-home teeth whitening
The two methods differ in location, agent concentration, and duration. The suitable method is determined by the dentist:
- In-office whitening: Performed by a dentist in the clinic, often with light or laser activation, higher concentration, shorter single session.
- At-home whitening: Custom trays are made based on individual teeth, with lower concentration whitening agent worn at home in multiple sessions.
- In some cases, both methods are combined for efficiency and maintenance.
Common causes of tooth discoloration
Understanding the cause helps discuss suitable options with the dentist; whitening effectiveness varies by cause:
- Extrinsic: Diet (coffee, tea, red wine), tobacco, or pigment deposits on tooth surface.
- Intrinsic: Internal tooth structure factors, such as tetracycline staining, fluorosis, or pulpal changes.
- Before whitening, issues like cavities or gum inflammation should be addressed, and the dentist confirms tooth and gum suitability.
