Rinses typically contain 1.5–2% hydrogen peroxide. Contact time is brief (around 60 seconds) compared to trays or strips.

No authoritative video is embedded here yet. We have not yet identified a short video from an authoritative source (ADA, licensed dentist channel, or licensed dental manufacturer) that focuses specifically on whitening mouthwash. Rather than embed a promotional clip, we're leaving this slot open until one is verified.
How it works
Peroxide contacts enamel during rinsing and may reduce surface stain over time.
Short contact time limits how deep the effect can go.
Best for
Users who prefer a rinse to gels or strips.
Adjunct to a full oral hygiene routine.
What to consider
Not a fast route to visible change on its own.
Alcohol-containing rinses may not be suitable for people prone to dry mouth.
Evidence note
Expected shade change
Typical range on a VITA-style shade guide. Actual results depend on stain type, starting shade, and adherence.
