Dental Whitening
Dental whitening is a cosmetic treatment that reduces stains and safely restores brightness to your smile. On this page, you will understand how the procedure works, who it is recommended for, how long results last, and which care habits help maintain the outcome for longer.
What is dental whitening?
Dental whitening is a procedure performed with specific peroxide-based gels that act on the tooth structure to soften pigmentation. The goal is to make teeth lighter without changing the natural shape of your smile.
How the treatment works
Before starting, we perform a clinical assessment to check oral health, identify visible restorations, and set realistic shade expectations. With this planning, we choose the most suitable technique for each case and monitor progress throughout treatment.
Types of dental whitening
In-office whitening: performed at the clinic with high-performance products, ideal for those looking for greater convenience and close professional follow-up.
Supervised at-home whitening: done with custom trays and guided gel use at home, with periodic reviews for safety and result control.
Combined technique: in some cases, we combine in-office and at-home treatment to enhance the result and improve shade stability.
Who whitening is recommended for
In general, treatment is recommended for patients with teeth darkened by pigmented foods, coffee, tea, red wine, smoking, or natural aging. Recommendation always depends on professional evaluation.
When whitening may not be recommended
Pregnant or breastfeeding patients, and patients with active cavities, gum inflammation, or severe sensitivity should be carefully evaluated before the procedure. It is also important to remember that restorations, crowns, and veneers do not whiten like natural teeth.
How long do dental whitening results last?
On average, results can last from 1 to 2 years, depending on diet, oral hygiene, and maintenance routine. Occasional touch-ups, when indicated, help preserve smile brightness.
Care before and after whitening
Maintaining good oral hygiene, following product usage guidelines, and reducing highly pigmented foods during the first 48 hours after sessions are important measures to protect results.
