Gums are isolated with a barrier before a 25-40% peroxide gel is applied — the isolation is why the concentration can be that high. This page covers the in-office whitening appointment itself — what is prepared beforehand, what happens in the chair, and what the first hours afterwards feel like. Plan for 1-2 appointments and 2-3 days.
An in-clinic session takes 60-90 minutes across three or four gel applications; a home regime runs 30-60 minutes daily for one to two weeks. No anaesthetic. The only sensation is a sharp cold-like zing during or after the session, caused by peroxide reaching the dentinal tubules.

A resin dam is painted and cured over the gum margin. Bleach on gum tissue causes an immediate white burn, so this step is the whole safety margin.
High-concentration peroxide is applied, left for a set time and suctioned off, repeated three or four times with a shade check between cycles.
A fluoride or potassium nitrate gel is applied at the end, and take-home trays are issued if a top-up phase is part of the plan.
Professional-strength whitening gel applied and monitored by a dentist chairside.
You leave with written aftercare and the follow-up schedule fixed — for this option that means 2-3 days, with 1-2 appointments in total.

An in-clinic session takes 60-90 minutes across three or four gel applications; a home regime runs 30-60 minutes daily for one to two weeks.
A dentist or a hygienist under dentist supervision applies the gel. The examination that comes first matters more than the light: whitening over decay or a leaking filling is what causes lasting pain.
Teeth look chalky and dehydrated immediately afterwards; the true shade settles about 48 hours later. Sensitivity peaks in the first 24 hours and fades.
Cost and alternatives for In-Office Whitening.
Compare vs alternatives → See full cost breakdown →Two to six on average, and more if staining is heavy to start with. Grey staining lifts far less.
Yes — a common protocol is one in-office session followed by maintenance trays.
Ask for the guide reading before and the expected number of shades. Two to four shades is normal; a jump to the brightest tab on the guide is marketing.
No. Restorations keep their original shade, so if front teeth are restored the plan has to include replacing them or accepting a mismatch.
Confirm it exists. Potassium nitrate before and after materially reduces the post-session zingers most patients complain about.
1-2 appointments — and 2-3 days. Any quote that compresses that materially is worth a second read, because laboratory and healing time set the schedule, not the clinic diary.
Home kits are cheaper and gentler but take two weeks; laser whitening adds light activation to the same idea.
Targeted application is easier under supervision.
Professional isolation removes most of that risk.
Supervision is the practical difference here.
