Philips Zoom Teeth Whitening in Bangkok

What is Philips Zoom WhiteSpeed teeth whitening?

Philips Zoom WhiteSpeed is an in-clinic teeth whitening system. A dentist applies a professional-strength whitening gel to the front teeth and activates it with the Zoom blue LED lamp in three to four 15-minute cycles. The whole visit takes about 45 to 60 minutes, and teeth typically finish several shades lighter, with Philips reporting results of up to 8 shades from a single session.

Zoom teeth bleaching vs whitening: the same treatment

"Zoom teeth bleaching" and "Zoom teeth whitening" describe the same in-clinic procedure. The professional whitening gel lifts the stains inside the enamel, so dentists say whitening and patients often say bleaching. At HeySmile the Zoom bleaching session costs 7,900 THB and takes about 45 to 60 minutes.

How the Zoom procedure works, step by step

1. Assessment and shade check. The dentist examines your teeth and gums, records the starting colour on the VITA shade guide and confirms you are suitable. Untreated cavities or gum inflammation are treated first.
2. Cleaning. Plaque and surface stains are polished off so the gel reaches the enamel evenly.
3. Gum and lip protection. A cheek retractor, a light-cured resin barrier on the gums and a lip balm isolate the soft tissue from the gel.
4. Gel application. The professional-strength Zoom gel is painted onto the visible surfaces of the upper and lower front teeth.
5. LED activation. The Zoom WhiteSpeed lamp shines on the gel for 15 minutes. The gel is then replaced and the cycle repeated, three to four times in total depending on sensitivity and the shade you are aiming for.
6. Finish. Gel and barrier are removed, the final shade is recorded next to your starting shade, and a post-whitening fluoride or desensitising gel is applied.

Aftercare: the first 48 hours after Zoom whitening

• Keep to a "white diet" for 48 hours: water, milk, plain rice, chicken, fish, white bread, bananas, pasta without coloured sauce.
• Avoid coffee, tea, red wine, cola, curry, soy sauce, berries and tobacco. Freshly whitened enamel picks up stains more easily for the first two days.
• Mild tooth sensitivity is common and usually settles within 24 to 48 hours. A sensitivity toothpaste or the desensitising gel provided helps.
• Skip coloured mouthwash and dark lipstick for two days, and brush gently with a soft brush.

How long do Zoom whitening results last?

Results typically last 12 to 24 months with normal habits. Coffee, tea, red wine and smoking shorten this, while a professional cleaning every six months and an optional take-home touch-up kit extend it. Whitening changes natural enamel only: crowns, veneers and fillings keep their existing colour, so the dentist checks these before treatment.

Who is not suitable for Zoom whitening?

Zoom whitening is not carried out for patients who are pregnant or breastfeeding, under 18, or who have untreated cavities, gum disease, exposed root surfaces or cracked teeth until these are resolved. Grey or tetracycline-stained teeth respond less predictably; where whitening is unlikely to give the result you want, the dentist will explain alternatives such as veneers instead.
