There is office care at the dentist's office and home bleaching at home. In both cases, the bleaching gel is used to bleach the surface of the teeth.
For home care, place the gel in a customized tray and have it used for 2 to 8 hours a day (depending on concentration). Although there are individual differences, the results usually appear in about 3 days. After that, use it for a few more days while controlling it, and drop it to the shade you want.
With office treatment, about an hour of treatment will be effective for three days of home care. Recommended for those who do not have time.
