Professional Teeth Whitening

Teeth whitening is recommended when your natural enamel looks yellow, brown, or dull and regular brushing or professional cleaning no longer restore brightness. It works best for extrinsic stains from coffee, tea, red wine, smoking and mild age-related discoloration on otherwise healthy teeth and gums.

The main types of teeth whitening are:

• In-office professional whitening (laser/LED systems such as Opalescence, Fläsh, and Zoom)
• Dentist-supervised at-home whitening kits with custom trays
• Over-the-counter products such as strips, pens, and LED kits
• So-called “natural” remedies such as charcoal or baking soda (not recommended as a primary method)

Each option differs in speed, effectiveness, sensitivity risk, and cost.

In-office whitening uses high-concentration hydrogen peroxide or carbamide peroxide gels activated with LED or laser light. One session typically lasts 60-90 minutes and can lighten teeth by several shades in a single visit, which is why it is often chosen before weddings, events, or photoshoots.

 In-office teeth whitening typically costs around €200–€350 in Turkey, while dentist-supervised at-home trays are usually in the €120–€200 range, and over-the-counter kits are cheaper at roughly €20–€50, but also weaker and slower in their effect. Even high-end in-office systems in Turkey are often significantly more affordable than similar treatments in the UK or USA, which is why many patients choose Turkey for professional whitening.

At Maltepe Dental Clinic, we offer two professional whitening systems – Opalescence (USA) and Fläsh (Germany). Based on your dental condition, sensitivity and aesthetic expectations, our team will guide you to the most suitable option and provide clear, detailed pricing information as part of your personalised treatment plan.

Results typically last from several months to a few years, depending on your diet, oral hygiene, and lifestyle habits. Touch-up treatments can extend the results.

In LED teeth whitening, blue light or laser energy is used to accelerate the chemical reaction of the whitening gel; the light itself does not bleach teeth. The real whitening effect comes from the peroxide percentage and contact time with the enamel. LED/laser systems can shorten chair time and yield faster results than non-light methods using the same gel.

Professional whitening is highly effective on most extrinsic (surface) stains. Intrinsic stains (inside the tooth) may require additional cosmetic treatments, such as veneers.

With teeth whitening, you cannot select an exact shade. The results depend on your natural tooth structure and typically lighten by one or more shades. The outcome will always look natural. If you prefer a specific shade or a brighter, uniform color beyond what whitening can achieve, we recommend treatments like porcelain veneers.

Many “natural” products, such as activated charcoal and baking soda, are abrasive and can scratch enamel if used too often. They may remove some surface stains but do not change internal tooth color, and frequent use can increase sensitivity and make teeth stain more easily again. Dentists usually recommend professional whitening systems instead of DIY abrasive methods.

For patients with sensitive teeth, dentists generally recommend lower-concentration whitening gels (5-10% carbamide peroxide), shorter application times (30-60 minutes), and enamel-safe formulas containing ingredients such as potassium nitrate or fluoride. Combining whitening with remineralizing gels can help soothe the nerves and strengthen enamel while still achieving visible brightening.

At Maltepe Dental Clinic, your oral health is our top priority. If you have tooth sensitivity, we first focus on treating and eliminating the sensitivity and, when necessary, avoid teeth whitening altogether to ensure your long-term dental health.

Most patients see their teeth become about 2-8 shades lighter on a standard shade guide after professional whitening. In-office treatments provide immediate results, while take-home trays normally work over 10-14 days, and OTC strips may need several weeks. Whitening can only brighten natural enamel – it does not change the color of crowns, veneers, or fillings.

Yes, when performed under professional supervision, teeth whitening is very safe. The main risks are temporary tooth sensitivity, gum irritation, and, with overuse, enamel weakening. Dentists control gel strength, exposure time, and protect the gums to keep whitening within a safe range.

On average, professional whitening results last between 6 and 12 months. Longevity depends on habits: frequent coffee, tea, red wine, dark foods, or smoking will shorten the lifespan of your results, while good oral hygiene and regular professional cleanings help keep your smile bright for longer. Some patients use touch-up trays every few months for maintenance.

As a general guide:

• In-office whitening: about once per year is usually enough.

• At-home kits: maintenance every 6-12 months under dentist guidance.

Whitening too frequently can lead to enamel erosion, gum irritation, and an unnatural, over-bleached look, so it should only be repeated when new discoloration appears and your dentist agrees it’s safe.

In the first 48-72 hours, enamel is slightly more porous, so you should:

• Avoid coffee, tea, red wine, dark sauces, berries, and other strongly colored foods

• Avoid or minimize smoking and vaping

• Use a soft toothbrush and non-abrasive toothpaste

• Rinse with water after meals and acidic drinks

These steps protect freshly whitened teeth from immediate re-staining.

To keep your teeth white for months after treatment:

• Limit daily stain sources or drink them through a straw

• Brush twice a day with a fluoride whitening toothpaste

• Schedule professional cleanings every 6 months

• Use dentist-prescribed touch-up trays if recommended

• Stay well-hydrated so pigments are washed away before they bind to enamel

Teeth whitening is best for adults with healthy gums, intact enamel, and surface stains from diet or smoking. It is not recommended for pregnant women, children, or patients with untreated cavities, gum disease, or severe enamel wear until these issues are treated. People with sensitive teeth can still whiten, but need a customized, gentler protocol.

No – bleaching gels only affect natural enamel. Crowns, veneers, bridges, and fillings will stay the same shade, so if they are visible when you smile, they may need to be replaced or adjusted after whitening. Root-canal-treated (“dead”) teeth often require internal bleaching or a crown/veneer for a uniform color.

Severe fluorosis and tetracycline discoloration are more resistant to whitening. Professional bleaching may lighten them slightly, but the results are often limited. In many of these cases, porcelain veneers or crowns – or a combined approach with whitening plus restorations – provide a more predictable cosmetic solution.

Common side effects include temporary tooth sensitivity, gum irritation if gel touches soft tissues, and with overuse, enamel thinning and increased susceptibility to future staining. When whitening is planned and monitored by a dentist, these risks are greatly reduced and usually short-lived.

• Teeth whitening: lightens natural enamel with peroxide gels.

• Porcelain veneers: thin ceramic shells that change the color, shape, and alignment of front teeth.

• Scaling and polishing (deep cleaning): removes plaque, tartar, and minor surface stains to improve oral health, but does not significantly change tooth shade.

Often, the best results come from combining a professional cleaning before whitening, and adding veneers or bonding later if structural or alignment issues remain.

Turkey is a leading destination for teeth whitening abroad, combining modern led/laser systems, internationally certified materials, and English-speaking teams with prices around €200-€350 for in-office whitening – far below many UK/US fees that can reach €1,000. Clinics in Istanbul are especially popular because patients can complete treatment in a single visit and combine it with a city trip.
