How LED Whitening Kits Work

LED whitening kits use a blue light to activate the whitening gel (usually hydrogen peroxide or carbamide peroxide). The light speeds up the chemical reaction, breaking down stains faster. Most LED kits take 10–20 minutes per session, and you can see results in 1–2 weeks.

LED lights are safe for most people, but they can cause temporary sensitivity in some users.

Non-LED Whitening Kit Functionality

Non-LED kits use the same whitening gels, but they rely on time instead of light to break down stains. You leave the strips or trays on for 30–60 minutes per session, and results take 2–4 weeks to appear.

Non-LED kits are often more affordable and gentler on sensitive teeth and gums.

Comparing Effectiveness of Both Options

Both LED and non-LED kits can brighten your smile by 2–5 shades. LED kits work faster, but non-LED kits are more gradual. The key is to choose a kit with a safe concentration of peroxide (3–6% hydrogen peroxide) and follow the instructions closely.
