How is teeth whitening done?

Teeth whitening can be done in two ways: professional whitening in an in-office setting and at-home whitening. In-office whitening uses special gels and light/laser-assisted systems, and the process takes approximately 30-60 minutes. In at-home whitening, custom trays are prepared, and the patient applies whitening gel to these trays and wears them for several days. The method chosen depends on the tooth structure and the patient’s needs.
