Walk down any chemist aisle in Canberra and you'll find a dozen products promising a whiter smile. Some work a little. Some don't work at all. A few actively harm your enamel. Here's an honest guide from the chair side of the conversation.
Why teeth stain in the first place
Stains come in two kinds. Surface stains sit on the enamel — coffee, tea, red wine and tobacco are the usual suspects. Deeper stains live within the tooth structure itself, from ageing, certain medications, or childhood illness. The distinction matters, because only one kind responds to shop-bought products.
What professional whitening does differently
Professional whitening uses a prescription-strength gel that reaches both kinds of stain, applied under supervision that protects your gums and enamel. In-chair whitening delivers visible change in a single appointment of around 60 to 90 minutes. Custom take-home trays brighten more gradually over one to two weeks, with results you control.
Just as important is what happens before the gel: a proper examination. Whitening over undiagnosed decay or gum disease is uncomfortable and unwise, which is exactly why the strongest products are only available through a dentist.
What to avoid
Charcoal pastes abrade enamel — the whiteness they reveal is literally your tooth wearing away. Acidic DIY remedies like lemon juice do the same. And LED kits without professional-grade gel mostly illuminate your hopes rather than lift your stains.
How long results last
With sensible habits and occasional top-ups, professional whitening holds for one to three years. Rinsing with water after coffee, using a straw for iced drinks and keeping up six-monthly cleans all extend the result considerably.
