Whitening at home
Home whitening under the guidance of a dentist
is equally effective, but a more gradual method. The dentist takes an impression of the dental arches and makes customised trays, into which a lower
concentration of whitening gel is placed. The patient wears the trays daily for a certain period of time (usually 10–14 days), following specific
instructions for use. This process allows for greater control over the intensity of the result and is often more tolerable for those with increased
tooth sensitivity. In many cases, combining the two methods gives the best results: initial whitening at the dentist's
office for immediate color improvement, and continuation or maintenance at home to stabilize and maintain the results long-term.
