About Teeth Whitening
One of the most common desires patients have is whiter teeth. When considering your options it is important to consult your dentist to make sure you have all the facts and understand how they may affect your teeth and mouth. Many people think the coloring of teeth is due to plaque or dirt. But a variety of factors can affect the color of your teeth including food, drink, tobacco, age, injury, and medications. Understanding what is causing the discoloration is important to properly whiten your teeth. Teeth whitening products use bleaches (either hydrogen peroxide or carbamide peroxide) to break stains into smaller pieces, which make them harder to see and make your teeth brighter. These bleaches do not work on all teeth, so it is important to consult your dentist before any treatment. Whitening will not be effective on caps, veneers, crowns, fillings or if the color is caused by medications or injury. Options for teeth whitening usually include whitening toothpastes, at-home bleaching, and in-office bleaching. Of course effectiveness, safety, and results vary greatly between products, so consult with your dentist if you are considering these choices.
Reasons People Whiten
Gradual yellowing with age, as enamel thins and the darker dentine beneath shows through more. Staining from coffee, tea, red wine, cola and dark sauces. Tobacco staining, which is among the most responsive to professional whitening. A specific event: a wedding, a graduation, a job that involves being photographed. Feeling that your teeth look darker than they used to in photographs. Wanting to lighten the natural teeth before having a crown or veneer made, so that the new restoration can be matched to the lighter shade rather than the old one. This is a sequencing detail people frequently get wrong, since restorations do not whiten afterward.
Benefits of Professional Whitening
The important benefit of doing it through a dental office is diagnostic rather than cosmetic: we identify what is actually causing the discolouration first. Bleaching does nothing for staining from medication such as tetracycline, or for a single tooth darkened by old trauma, and someone who buys a kit for those will spend money and get nothing. Professional whitening is also stronger and more evenly applied than over-the-counter strips, so results are more predictable and reached faster, and custom trays keep gel on the teeth rather than on the gums, which is where most of the burning and irritation from generic kits comes from. Sensitivity is anticipated and managed — usually with a desensitising agent and by adjusting how long the gel is worn — rather than being something you endure and abandon halfway through.
What to Expect
We start with an examination, because whitening an untreated cavity or inflamed gums is uncomfortable and unwise, and because a cleaning alone often removes more surface staining than people expect. We then check what restorations you have in the visible zone: whitening will not be effective on caps, veneers, crowns or fillings, so if you have a crown on a front tooth, whitening the teeth around it will make that crown stand out, sometimes the honest recommendation is to whiten and then replace the crown to match, and sometimes it is not to whiten at all. For in-office treatment the gums are isolated and protected before gel is applied. For take-home, impressions are taken for custom trays and you are shown how to load and wear them. Some sensitivity to cold during and shortly after treatment is common and temporary; overuse of whiteners can cause lasting damage, which is exactly why supervision is worth having.

Terms You May Hear
- Extrinsic stain
- Surface staining from food, drink and tobacco. Responds well to cleaning and whitening.
- Intrinsic stain
- Discolouration from within the tooth, from medication, injury or age. Often does not respond to bleaching and may need a veneer or crown.
- Carbamide peroxide
- One of the two bleaching agents used in whitening gels; it breaks down into hydrogen peroxide more slowly, which suits take-home trays.
