Coffee, tea, smoking, age — teeth naturally darken over time. Professional whitening lifts surface and intrinsic stains in a single in-chair session, with results visible immediately and full effect setting in over 48 hours.
Over-the-counter strips use weak concentrations of bleaching agent (usually 6–10% hydrogen peroxide) and work slowly over weeks. Professional in-chair whitening uses a higher-concentration gel applied under controlled conditions, with gum protection, and activated either chemically or with a curing light. Result: faster, more dramatic, more uniform.
Yes. Professional whitening at a dental clinic includes pre-treatment evaluation, customized gum protection, and a controlled application time. We don't whiten teeth with active decay, exposed roots, or fresh restoration work, because the chemistry can cause sensitivity. The whitening agent itself does not weaken enamel when used properly.
Most patients lift 4–8 shades on the standard dental shade guide in one session. Beyond that, very-white results require multiple sessions or a take-home top-up kit. We'll discuss realistic expectations during consultation.
No. Crowns, veneers, bonding, and fillings don't respond to whitening agents — they stay the colour they were when made. If you whiten and have visible restorations, those restorations may need to be redone afterward to match the new tooth colour. This is part of why we discuss the plan with you before treatment.
Typically 1–2 years with normal habits. Smoking, daily coffee, and red wine shorten that window. We can provide a maintenance pen or take-home top-up gel.
