In-office whitening (Zoom-style)
A high-concentration peroxide gel applied in 15–20 minute sessions during a single visit, often with light activation. Results visible the same day. Best for: weddings, events, patients who want a single dramatic change. Side effects: temporary sensitivity for 24–48 hours is common.
Take-home professional trays
Custom-molded trays plus professional-strength gel you wear 30 minutes to overnight, depending on the formula, for 1–2 weeks. Best for: patients who prefer a gradual change, deeper stains, or maintenance after in-office whitening. Side effects: same temporary sensitivity, usually milder because the concentration is lower.
Over-the-counter whitening strips
1/3 the strength of professional formulas. Useful for maintenance between professional treatments, but unlikely to produce dramatic change. The tray fit is generic, which limits results.
Will whitening work on my teeth?
External stains (coffee, tea, wine, smoking) respond well to whitening. Internal stains (tetracycline, fluorosis, trauma) often don’t — for these, veneers may be the only path to a brighter smile. Existing crowns, veneers, and fillings do not whiten — only natural enamel does. Whiten first, then color-match restorations.
Frequently asked
How much does professional teeth whitening cost in Dublin?
Pricing for professional whitening is finalized at your visit because the right approach (in-office vs. take-home, and how many sessions) depends on your starting shade, the cause of the staining, and your goals. We'll discuss it openly during your appointment and you'll leave with a clear plan and an itemized fee.
Does professional whitening hurt?
Most patients experience mild sensitivity for 24 to 48 hours after professional whitening. The sensation is similar to drinking very cold water on cold-sensitive teeth. Pre-whitening desensitizing gel reduces this for most patients.
How long do whitening results last?
Professional whitening results typically last 1 to 3 years before noticeable re-darkening, depending on coffee, tea, wine, and tobacco habits. Touch-up trays once or twice a year extend results indefinitely.
Can I whiten teeth with crowns or veneers?
No — porcelain crowns, veneers, and bonded fillings do not whiten. They retain their original shade while surrounding natural teeth lighten. Always whiten before placing new cosmetic work, then color-match the restorations to your new shade.
Is whitening safe?
Yes, when done with professional-grade products and proper tray fit. Over-the-counter strips with poor fit can cause uneven whitening and gum irritation. Custom trays from your dentist deliver more even, predictable results.
