How long does teeth whitening take?
In-office whitening takes about 60-90 minutes for a single session. Take-home whitening involves wearing custom trays for 30-60 minutes daily for 1-2 weeks. You will see initial results from take-home trays within a few days, with full results after completing the treatment course.
