What is it?
Professional teeth whitening is a cosmetic treatment that lightens the natural color of teeth by removing extrinsic stains (coffee, wine, tea, tobacco) and intrinsic stains (aging, medication, fluorosis). It uses hydrogen peroxide or carbamide peroxide at concentrations only a professional can safely handle.
Unlike pharmacy products or whitening toothpastes, professional whitening achieves real changes in tooth shade — typically between 4 and 8 shades lighter. The difference is noticeable from the first session and stabilizes over the 2 weeks following the treatment.
It is not an aggressive treatment: tooth enamel is not damaged when performed by a licensed dentist following the correct protocol. Temporary sensitivity is the most common side effect and disappears within 24-48 hours.
How is the process?
- 1
Initial assessment
The dentist checks the state of your teeth, gums and fillings. Not all patients are candidates: active cavities, gingivitis or visible restorations must be treated first.
- 2
Professional cleaning
A dental cleaning is performed first to remove plaque and tartar, ensuring the whitening agent acts directly on the enamel.
- 3
Application of whitening agent
Depending on the modality (in-clinic, at-home, or combined), the whitening gel is applied. In-clinic it is activated with LED light for 45-60 minutes. At home, custom trays are used for 1-2 weeks.
- 4
Review and maintenance
A week later the result is reviewed and recommendations are given to maintain the shade as long as possible.
How long does it take?
An in-clinic session lasts 60-90 minutes. At-home treatment requires 7-14 days of tray use, 1 hour per day. The combined treatment (clinic + home) is completed in 2-3 weeks and usually offers the most stable results.

Expected results
Results are visible from the first session and stabilize in 1-2 weeks. The duration of the effect depends on habits: with good hygiene, no smoking and limited coffee/wine, intense whiteness is maintained 12-24 months. Touch-ups can later be done at home with the trays to refresh the shade.
Aftercare
- First 48 hours: white diet (avoid coffee, tea, red wine, tomato sauce, dark fruits)
- No smoking during the first 24-48 hours
- If sensitivity appears, use sensitive teeth toothpaste for 1 week
- Maintain regular hygiene (brushing, floss, mouthwash)
- Professional review and cleaning every 6 months
Frequently asked questions
Does teeth whitening damage enamel?
No, when performed by a licensed dentist following professional protocol. Whitening products act on the surface without weakening the enamel structure. Temporary sensitivity is the only common side effect and disappears within a few days.
How long do whitening results last?
Between 12 and 24 months depending on the patient's habits. Coffee, red wine, tea, dark sodas and especially tobacco accelerate shade loss. With good hygiene and maintenance it can last more than 2 years.
Does it work on fillings and crowns?
No. Whitening only lightens the natural tooth. White fillings, veneers and crowns keep their original color, so they may become visible after the treatment. The dentist will warn you if this is your case so you can decide whether to replace the restorations.
What is the difference between in-clinic and at-home whitening?
In-clinic whitening (45-60 min) uses higher concentrations and LED light, giving immediate results. At-home (1-2 weeks) uses lower concentrations over more time, with gradual but equally effective results. The combined approach mixes both for maximum stability.
