Frequently asked questions
Is teeth whitening safe?
Yes, when performed by a dentist. In-clinic bleaching isolates the gums and controls contact time, which over-the-counter kits cannot do.
Will whitening work on crowns or fillings?
No. Ceramic and composite restorations do not lighten, so they may need replacing to match your new shade.
