Brighten Your Smile. Feel More Confident—Fast.
Stains from coffee, tea, wine, tobacco, and everyday life can make teeth look dull over time. Our professional teeth whitening service is a quick, in-office cosmetic treatment designed to lift stains and brighten your natural tooth shade—without a long recovery or downtime.
What Is Teeth Whitening?
Teeth whitening is a cosmetic service that uses a peroxide-based whitening gel to help lighten the appearance of natural tooth enamel by breaking down and lifting stain molecules. It’s a popular, non-invasive way to refresh your smile before a big event—or simply because you want to look and feel your best.
Important note: Whitening works on natural teeth only. It does not whiten crowns, veneers, bonding, or tooth-colored fillings.

How Teeth Whitening Works
The Science Behind Teeth Whitening
Whitening gels typically use hydrogen peroxide or carbamide peroxide to break stain compounds into smaller, less visible particles—making teeth look brighter. This reaction works on both surface (extrinsic) stains and some deeper (intrinsic) discoloration, depending on the cause of the stain and your natural tooth structure.
Because everyone’s enamel and stain patterns are different, results vary. Yellow-toned teeth often respond better than gray-toned discoloration, and some internal discoloration may be more resistant.

Frequently Asked Questions
Honest answers to common questions
Is teeth whitening safe?
When performed appropriately, professional teeth whitening is generally well-tolerated. The most common side effects are temporary tooth sensitivity and temporary gum irritation, which typically resolve.
Will whitening work on crowns, veneers, or fillings?
No. Whitening only affects natural tooth enamel. If you have crowns, veneers, bonding, or tooth-colored fillings, those restorations will not change shade and may look different next to newly whitened teeth.
How long do results last?
Results vary based on diet, oral hygiene, and lifestyle. Many people maintain results for months (or longer) with good brushing/flossing habits and mindful intake of staining foods/drinks. Your take-home pen can help with touch-ups.
Will I have sensitivity after whitening?
Some people experience mild, temporary sensitivity—especially to cold air or cold drinks. If you’re prone to sensitivity, consider the option that includes the enamel booster, and follow the aftercare instructions we provide.
How white will my teeth get?
It depends on your starting shade and the type of discoloration. Yellow-toned stains often respond well, while gray tones or certain internal stains may respond less. We aim for a natural-looking brightening that fits your smile.
Who may not be a good candidate for teeth whitening?
Whitening may not be recommended if you have untreated cavities, gum disease, significant sensitivity, or if you’re currently managing dental pain. If you’re pregnant or breastfeeding, it’s best to consult your dentist/healthcare provider before whitening.
What should I avoid after my appointment?
For best longevity, avoid heavy stainers (like coffee, red wine, dark sauces, and tobacco) for a short period after whitening, and follow the maintenance plan you receive at your visit.
