Teeth whitening (bleaching) is one of the fastest and most affordable cosmetic dentistry treatments; by lightening the shade of your teeth it gives you a brighter, more youthful smile. At the practice of Dr. Zahra Sadat Shamekhi, a DHA-licensed general dentist practising since 2013 in Vanak, Tehran, whitening is carried out to a proper standard — safely and tailored to the condition of your teeth.
If your teeth have darkened because of coffee and tea, tobacco or ageing, bleaching can lighten them by several shades without any tooth reduction and completely safely. Below you will learn about the types of bleaching, the causes of discolouration, the steps, its safety and how long it lasts.
Bleaching (whitening) is a process in which whitening gels containing hydrogen peroxide or carbamide peroxide break down the coloured molecules within the tooth structure, removing both surface and deeper stains. Unlike scaling, which only removes surface deposits, bleaching lightens the intrinsic colour of the tooth by several shades and restores the natural brightness of your smile.
In-office (chairside) whitening: with a concentrated gel and a special light in a single visit, for fast and dramatic results.
At-home whitening: with a custom tray and a milder gel, over several nights and under the dentist's supervision.
Combined approach: starting in the office and continuing at home for the best and longest-lasting result.
Understanding the cause of darkening helps in choosing the best treatment. The most important causes include:
Heavy consumption of coffee, strong tea and coloured drinks
Tobacco and cigarette use
Ageing and thinning of the tooth enamel
Certain medications and poor oral hygiene
At Dr. Shamekhi's practice the whitening process is safe, painless and fully principled:
01. Examination, assessment of tooth and gum health and recording the initial shade
02. Scaling and cleaning the tooth surface before whitening
03. Protecting the gums and applying the whitening gel to the teeth
04. Activating the gel, evaluating the result and providing maintenance advice
Standard bleaching performed under a dentist's supervision is a safe procedure and does not damage the tooth enamel; you may only experience mild, temporary cold sensitivity for a few days, which is controllable. What is dangerous is the unsupervised use of non-standard whitening products without gum protection, which can harm both the teeth and the gum tissue — which is exactly why professional supervision matters.
Darkening from coffee and tea
Yellowing of teeth with age
Stains caused by tobacco
A desire for a brighter smile
Dr. Zahra Sadat Shamekhi, a DHA-licensed general dentist practising since 2013, carefully assesses the health of your teeth and gums before whitening and, with proper gum protection and standard materials, performs the procedure safely and in harmony with your natural facial tone. This care guarantees a bright result with minimal sensitivity.
Avoid staining foods such as coffee, tea and dark sauces for the first 48 hours
Stop or reduce tobacco use to maintain the whiteness
Use a suitable toothpaste for sensitive teeth if needed
Brush and floss regularly and attend periodic scaling for longer-lasting results

ماندگاری بلیچینگ معمولاً بین ۶ ماه تا ۲ سال است و به عادات غذایی و بهداشت فرد بستگی دارد. کاهش مصرف قهوه، چای پررنگ و دخانیات و رعایت بهداشت دهان، اثر آن را طولانیتر میکند.
بلیچینگ استاندارد زیر نظر دندانپزشک بیخطر است و به مینای دندان آسیب نمیزند؛ تنها ممکن است تا چند روز حساسیت خفیف موقت ایجاد شود. استفادهی خودسرانه از مواد غیراستاندارد است که خطرناک است.
بلیچینگ مطبی با ژل غلیظتر و فعالسازی نور نتیجهی سریع میدهد؛ بلیچینگ خانگی با تری سفارشی و ژل ملایمتر تدریجیتر است. اغلب ترکیب این دو بهترین نتیجه را دارد. برای مشاوره با شماره ۰۲۱-۸۸۰۵۰۷۹۴ تماس بگیرید.
