Teeth Whitening funktioniert durch den Einsatz von bleichenden Substanzen, die Verfärbungen und Flecken auf den Zähnen entfernen. Diese Substanzen dringen in den Zahnschmelz ein und brechen dort die Verfärbungen auf. Es gibt verschiedene Methoden für das Teeth Whitening, darunter professionelle Behandlungen beim Zahnarzt, Bleaching-Sets für zu Hause und natürliche Hausmittel wie Backpulver oder Aktivkohle. Es ist wichtig, vor dem Teeth Whitening eine gründliche Untersuchung der Zähne durchzuführen, um sicherzustellen, dass sie gesund sind und keine Schäden durch das Bleaching entstehen. Es ist auch ratsam, regelmäßige Pflege und Vorsorge zu betreiben, um die Ergebnisse des Teeth Whitening möglichst lange zu erhalten. **
