Philips Zoom WhiteSpeed In-Office Teeth Whitening

Perfect Smile offers in-office teeth whitening using the Philips Zoom WhiteSpeed system — one of the most widely used professional LED-accelerated whitening technologies. A hydrogen-peroxide whitening gel is applied to the teeth under gum protection and activated by the Zoom blue LED lamp in successive cycles within a single visit, lightening enamel by several shades in around 90 minutes. For the strongest result the clinic recommends its combined package, which pairs a full professional dental hygiene session (removing tartar and surface staining first) with the whitening treatment at a discounted 10,500 Kč. Whitening is a popular finishing step after clear-aligner treatment, completing newly straightened smiles.

Professional in-office whitening differs fundamentally from drugstore strips or whitening toothpastes: it uses clinical-concentration hydrogen-peroxide gel applied under controlled conditions with full soft-tissue protection, achieving in one visit what home products cannot. **The Philips Zoom WhiteSpeed system:** Zoom WhiteSpeed uses a 25% hydrogen-peroxide gel activated by a blue LED lamp with adjustable intensity. The light accelerates the breakdown of peroxide into reactive oxygen, which penetrates enamel and oxidises the pigmented organic compounds responsible for yellowing — from coffee, tea, red wine, tobacco, and natural age-related darkening. Treatment runs in three to four 15-minute gel cycles within a single appointment. **The session:** The hygienist records the starting shade, isolates lips and gums with retractors and a protective gingival barrier, applies the whitening gel, and positions the Zoom lamp. Gel is refreshed between cycles. The full visit takes roughly 90 minutes, finishing with a desensitising application. Results of several shades' improvement are visible immediately, with the final shade settling over the following days as enamel rehydrates. **Why pair with hygiene first:** Whitening gel works on clean enamel. Tartar and pigmented biofilm physically block gel contact, producing patchy results. Perfect Smile's combined package (10,500 Kč vs 11,490 Kč separately) schedules a full professional hygiene session — ultrasonic tartar removal, polishing, AIRFLOW stain removal — before whitening, which measurably improves evenness and brightness of the outcome. **After aligner treatment:** Whitening is the most common finishing treatment after Invisalign — patients who have invested in straight teeth complete the result with a brighter shade. Whitening is performed after orthodontic treatment ends, never during. **Sensitivity and aftercare:** Temporary tooth sensitivity for 24–48 hours is the most common side effect and is managed with desensitising agents. For the first 48 hours patients follow a 'white diet' — avoiding coffee, tea, red wine, coloured sauces, and smoking — while enamel pores close. Results typically last one to three years depending on diet and smoking habits. **Suitability:** Whitening works on natural enamel only — crowns, veneers, and fillings do not change shade, which the clinic assesses beforehand. Not performed during pregnancy or on patients with untreated cavities or gum inflammation (another reason the hygiene-first package is the recommended route).
