TRAYLESS Whitening Technique Part 1 - with Dr Wyman Chan - PDP277

What if the tray is the reason your whitening results are inconsistent?

Why would a dentist who owns a whitening lab — and holds four patents on making bleaching trays — tell you to skip the tray?

Trayless whitening does not mean strips. It means the patient puts in a retractor and paints the gel directly onto the teeth, twice a day, for half an hour. No impression, no lab bill, no two-week wait, and no soft plastic reservoir quietly absorbing your peroxide.

This is Part 1 of a two-part conversation with Dr Wyman Chanand Dr Elvis Law, recorded live in their central London whitening practice. Wyman has done nothing but whitening since 2002, has a PhD on the efficacy and safety of whitening processes, and — despite owning the lab that makes the trays — now does most of his cases without one. Elvis trained under him and reckons around 90% of his own cases are now trayless.

Part 1 is the mechanism, the protocol and an honest list of who it doesn’t suit. Part 2 takes it into the hard cases.

Protrusive Dental Pearl: Let the Patient Pick the Shade

Most of us ask “how white do you want to go?”, get a laugh about Hollywood white or Simon Cowell white, then hold a B1 tab against the canine and call that the destination. Try flipping it.

Under corrected light, record where the patient is now. Then hand over the whole shade guide, arranged by value, and let them choose the tab they want to reach. Photograph both.

This is the VITA Shade guide arranged by value:

B1 → A1 → B2 → D2 → A2 → C1 → C2 → D4 → A3 → D3 → B3 → A3.5 → B4 → C3 → A4 → C4

Two things change. You now know the target precisely instead of inferring it, and you can track progress against a fixed reference. Most patients land on B1 — it’s the last shade before the bleach range, and it reads natural rather than veneered. Some will point at 0M1 and that’s a different conversation, which is exactly the point.

Because whatever they choose dictates how many weeks, how much gel and how many reviews the case needs — and therefore what it should cost. A single flat whitening fee assumes every case takes the same work. They don’t. Someone starting at C4 who wants a bleach shade can get there, but it takes more gel, more time, more reviews and probably a protocol change along the way. Price that honestly.
