What Are Whitening Strips?

Whitening strips are thin, flexible plastic strips coated with a peroxide-based whitening gel. You apply them directly to your teeth, leaving them on for 10–30 minutes per session. The gel penetrates the enamel to break down surface and deep stains, gradually brightening your teeth over 2–4 weeks. Strips are affordable, easy to use, and require no special equipment, making them a popular choice for casual whitening.

What Are LED Whitening Kits?

LED whitening kits use a combination of peroxide gel and a blue LED light to accelerate the whitening process. The light activates the peroxide, breaking down stains faster than strips alone. Most kits include a mouth tray to apply the gel evenly, and sessions last 10–20 minutes. LED kits deliver faster results than strips, with many users seeing a noticeable difference in 1–2 weeks.
