Zoom whitening home kit

A take-home whitening kit uses a fitted tray and peroxide gel under instructions that control contact with teeth and gums.

A custom tray holds whitening gel against the tooth surfaces while limiting spread onto the gingiva.

Use only the supplied gel and tray instructions, keep gel off the gums, and do not extend wear time.

Have the kit reviewed if you have cavities, cracks, gum recession, ulcers, or significant sensitivity.

Ask who provides the tray, what peroxide concentration it contains, and how to load it.
