Istanbul Teeth Whitening — Deltadiş Oral and Dental Health Polyclinic

Whitening lifts the colour of natural tooth tissue. It does not repaint teeth, and it does not act on everything in your mouth — the part that usually goes unmentioned.

There are two kinds of discolouration. Surface staining from coffee, tea, red wine and tobacco sits on and just under the enamel and generally responds well. Internal colour is another matter: the natural shade you inherited, dentine showing through enamel that thins with age, tetracycline banding, or a single tooth that darkened after a root canal. These respond less predictably, and a pronounced tetracycline case may improve only modestly.

So the result differs from person to person. Your starting shade and the structure of your teeth set the ceiling, not the strength of the gel. White spots or fluorosis can stand out more for a while.

Crowns, veneers, composite fillings and bonding do not change colour at all. Whitening is also not advised during pregnancy, under 18, or with gum disease or untreated decay; the examination decides.

The examination comes first, with digital imaging where needed. Untreated decay, exposed root surfaces and inflamed gums are a reason to postpone whitening, not a detail to work around. Scaling and polishing usually precede the gel — removing hard deposits already changes how the teeth look.

In-office whitening is a single appointment of 45 to 60 minutes, the gel activated by LED or laser; two to three shades is a realistic order of magnitude. Home whitening uses custom trays and a milder gel over several days and suits travellers who want to continue after flying home. The two are often combined.

Sensitivity is the honest caveat. Cold twinges during treatment and for a day or two afterwards are common, they vary from person to person, and nobody can promise you will feel nothing. Fluoride and potassium nitrate help keep it manageable; tell the clinician early and concentration and timing can be adjusted.

The effect is not permanent: coffee, tea, red wine and smoking bring the colour back over roughly one to two years. A top-up is normal, not a failure.

Whitening kits bought online and treatments offered outside a clinic share one problem: nobody examines the mouth first. Gel over an untreated cavity, a cracked filling or receding gums causes pain and can make the underlying problem worse. The examination is the safety step, not the paperwork.

At Özel Deltadiş Ağız ve Diş Sağlığı Polikliniği in Kağıthane, Istanbul, 7 dentists with 15+ years of experience work across 5 separate clinical areas, with digital panoramic imaging on site. The polyclinic has treated over 10,000 patients, from 37 countries, and holds the Ministry of Health International Health Tourism Authorisation Certificate ST-6365 — a record that the clinic is audited against defined standards for patients from abroad, not a promise about your shade.

Instruments are sterilised; single-use items are used once. Interpreter support in English, Russian and German means the questions that matter beforehand — old fillings, a history of sensitivity, what you actually expect — get asked properly. Google rating: 4.6. That first examination costs nothing and includes digital imaging; you can arrange it on WhatsApp at +90 546 124 48 29.

Order matters. If veneers or crowns are anywhere in your plans, whiten first and choose the restoration shade afterwards; done the other way round, the new work is matched to teeth that are about to change colour. Existing crowns and fillings in the smile line will not lighten. Whether to replace them is a separate decision, taken with your dentist once the natural teeth have settled — usually about two weeks after whitening.

The first examination is free and includes digital imaging, and you leave with a written plan and a transparent price for your case. No figure appears here because it depends on the method and on what has to be treated first.
