Teeth Whitening (Bleaching) in Vanak, Tehran

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.

What is teeth whitening?

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.

Types of teeth whitening

• 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.

Causes of tooth discolouration

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

The teeth whitening procedure

At Dr. Shamekhi's practice the whitening process is safe, painless and fully principled:

1. 01. Examination, assessment of tooth and gum health and recording the initial shade
2. 02. Scaling and cleaning the tooth surface before whitening
3. 03. Protecting the gums and applying the whitening gel to the teeth
4. 04. Activating the gel, evaluating the result and providing maintenance advice

Is teeth whitening safe?

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.

Who is a candidate for bleaching?

• Darkening from coffee and tea
• Yellowing of teeth with age
