How it works

Your whitening appointment, step by step.

1 · Exam & cleaning

We start by checking for cavities, gum issues, or existing restorations that could affect whitening. A professional cleaning removes plaque and staining so the whitening agent works evenly across your teeth.
2 · Shade assessment

We record your starting shade so you can see exactly how much brighter your teeth become. This also helps us set realistic expectations and tailor the treatment to your goals.
3 · Professional whitening

The in-office whitening application takes about 60 minutes. Your gums are carefully protected while a professional-strength whitening agent is applied to your teeth by the dentist.
4 · Aftercare advice

We provide clear guidance on how to maintain your results — what to eat and drink in the first 48 hours, and how to keep your smile bright long-term.

Why choose professional whitening

Dentist-supervised Safer and more effective than salon whitening. Your dentist monitors the entire process and adjusts as needed.

Includes dental check-up Cavities, cracks, and gum problems are checked before whitening — so issues are caught early, not made worse.

Customized to your teeth Not one-size-fits-all strips or trays. The treatment is adapted to your tooth condition, sensitivity, and desired shade.

Common questions

Whitening FAQ.

How long do whitening results last?

Results typically last 6 months to 2 years depending on your diet and oral hygiene. Avoiding heavy staining from coffee, tea, red wine, and tobacco will help maintain your brightness. Touch-up treatments are available if you want to refresh your results.

Is teeth whitening safe?

Yes — professional whitening supervised by a dentist is safe for your teeth and gums. We use controlled concentrations of whitening agents and protect your gum tissue throughout the procedure. The pre-whitening exam also ensures there are no underlying issues that could cause problems.

Can I combine whitening with other treatments?

Yes. Many patients choose whitening before cosmetic work such as veneers or crowns, so the restorations can be shade-matched to your newly brightened teeth. We can plan the ideal sequence during your consultation.

What is the difference between salon whitening and dental whitening?

Salon (self-whitening) uses low-concentration agents that primarily remove surface stains. Professional dental whitening uses stronger, dentist-grade agents that penetrate enamel to change the actual shade of your teeth — with results that are more noticeable and longer-lasting. A dental whitening also includes a health check to make sure your teeth are ready for the procedure.
