Teeth Whitening
Chairside at 260 Stockton
Whiter in a single visit — and an honest answer about what whitening will and won't change.
Professional whitening lifts years of staining from coffee, tea, red wine and tobacco in one appointment, or gradually at home with trays made from impressions of your own teeth. Both use dental-grade peroxide at concentrations no retail product can sell you.
The part most whitening pages leave out: whitening only works on natural tooth structure, and not every kind of discolouration responds to it. We'll tell you which kind you have before you spend anything.

How it works
We find out why the teeth are dark
Surface staining, natural yellowing with age, and discolouration from inside the tooth are three different problems. Only the first two respond well to whitening — so we look before we treat.
We check the restorations first
Crowns, veneers, bonding and tooth-coloured fillings do not lighten. If you have any in the smile line, we whiten first and match new restorations to the final shade afterwards — never the other way round.
In-office, take-home, or both
In-office whitening is done in one appointment and you leave with the result. Take-home trays work more gradually over about two weeks and are gentler on sensitive teeth. Many patients do in-office once and keep trays for touch-ups.
We manage the sensitivity
Temporary sensitivity is the most common side effect and it is manageable — desensitising agents, shorter wear times, and spacing sessions out. Tell us early if you're prone to it and we'll plan around it.
Timing
When whitening is the right tool
Whitening is popular before weddings, graduations, holidays and photographs, and the timing matters. In-office whitening is finished the same day, so it can be done shortly before an event. Take-home trays need a couple of weeks to reach their best result — start those well ahead.
If you are planning other cosmetic work, whitening comes first in the sequence. It sets the shade everything else is matched to.
Professional vs retail
Why professional whitening outperforms the drugstore
Over-the-counter strips, rinses and whitening toothpastes are limited by what can safely be sold unsupervised. They lift surface stain, and for mild cases that may be all you need.
Professional treatment differs in three ways that matter:
- 01Stronger, dental-grade peroxide, applied with the gums protected
- 02Custom trays moulded to your teeth, so the gel sits on enamel instead of leaking onto gum tissue
- 03A clinician checking first that the discolouration is the kind whitening actually fixes
Keeping it
How long the result lasts
That depends almost entirely on what you drink and whether you smoke. Coffee, tea, red wine and dark cola will re-stain enamel over months; a rinse with water after them does more than most people expect.
Keeping your trays makes maintenance simple — a short top-up occasionally holds the shade rather than starting over. We'll show you how to use them so you don't overdo it.

Questions
Common questions
How long does in-office teeth whitening take?
A single appointment. You leave with the result the same day, which is why it suits patients whitening shortly before a wedding, graduation or photographs.
Should I choose in-office whitening or take-home trays?
In-office is faster and supervised. Take-home trays work gradually over about two weeks and are usually gentler if your teeth are sensitive. Many patients do in-office once and keep trays to maintain the result.
Will whitening work on crowns, veneers or fillings?
No. Whitening only changes natural tooth structure. Crowns, veneers, bonding and tooth-coloured fillings keep their original shade, so if you have restorations in your smile line we whiten first and match any new restorations to the final shade afterwards.
Does professional whitening make teeth sensitive?
Temporary sensitivity is the most common side effect and it typically settles within a day or two. It can be managed with desensitising agents, shorter wear times and spacing sessions further apart. Tell us if you're prone to sensitivity and we'll plan for it from the start.
Why not just use whitening strips from the drugstore?
Retail products use much lower peroxide concentrations because they're used unsupervised, and their trays or strips don't fit your teeth. They can lift light surface staining. For deeper or uneven discolouration they generally underdeliver.
Is teeth whitening safe?
Professionally supervised whitening has a long safety record. The safeguards are what matter: protecting the gums, using a properly fitted tray, and checking beforehand that the discolouration is the kind that responds to whitening rather than a sign of something else.
How long do whitening results last?
Months to a few years, depending mostly on coffee, tea, red wine and tobacco. Keeping your custom trays lets you top up occasionally instead of repeating the full treatment.
