How is teeth whitening performed?
The teeth whitening technique will take about an hour. To perform the procedure, the dentist uses a bleaching agent and a certain light energy that helps the bleaching gel to penetrate the enamel and whiten the teeth from within. As the technique removes any stains that exist on the outside of the tooth (extrinsic discoloration) as well as those beneath the enamel, it offers considerably whiter results immediately after the procedure.
The dentist uses light to accelerate the bleaching process and increase the effectiveness of the whitening agent. There are different types of power or light that can be used during bleaching. One of the most recent light beams used for teeth whitening is Phillips Zoom light. This source of energy can sufficiently activate the whitening gel without damaging the soft tissue or resulting in tooth sensitivity. In Iran, zoom light is used by the majority of cosmetic dentists because of its effectiveness and minimal risk of tooth sensitivity after the process.
It is important to note that the teeth whitening procedure is effective for people with good oral health and permanent teeth. People with dental crowns cannot achieve the same result on their crowned teeth.
Teeth whitening methods
There are multiple methods that can be used to whiten teeth. The type of teeth whitening technique will be chosen based on the degree of discoloration, your budget, age, and current dental condition. This is why examining patients before the procedure is highly important. Here are some of the main approaches that a dentist can take to whiten your teeth:
Light-assisted teeth whitening:
This is the most common type of teeth whitening. The dentist applies bleaching agent on your teeth and then emits a certain energy light to activate the substance.
Internal teeth whitening:
Patients who have undergone an endodontics procedure, often face tooth discoloration due to the absence of nerve inside the tooth. A tooth that has had a root canal tends to be darker and duller than the rest of your teeth. Also called a dead tooth, a root canal tooth cannot be whitened at the same rate that a healthy tooth can. To brighten the color of a dead tooth, dentists use internal bleaching technique. During this method, the bleaching agent is sealed off inside the tooth. It will be removed every few weeks until the desired whiteness is achieved.
Is it safe to perform professional teeth whitening?
Having the procedure in the fully equipped clinics of Iran can be a further reassurance that there will be minimal (if any) complications following the procedure.
Having professional teeth whitening in Iran: what to expect
After arriving at the airport and meeting your interpreter, you will be transferred to your hotel. When the appointment date arrives, you will visit your dentist at his/her office. With your personal interpreter at your side, you and the specialist will discuss the terms of the procedure. The dentist will ask about your expectations and the degree of whiteness you wish to achieve. Once you are prepared, the procedure begins. Here is how a teeth whitening is done, step by step:
- A dental impression of your teeth is taken to prepare your take-home whitening kit if you need one.
- The practitioner will pumice your teeth to remove any plaque on the tooth surface.
- Gauze and a contraption or mouth guard will be placed in your mouth to protect your gums and other soft tissue from the bleaching gel. Also, you will be given safety glasses to protect your vision from the laser/light beam.
- The bleaching agent (whether carbamide peroxide or hydrogen peroxide) is applied on your teeth.
- Once your teeth reach the desired shade, they will be rinsed. And, the dental specialist will reveal the results to you. You will immediately see whiter teeth and a brighter smile.
You might also be given at-home whitening kits. You can use these trays once a month to prolong the results.
Teeth whitening aftercare
Different individuals have different teeth and different dentists take different approaches when giving aftercare instructions to their patients. Some specialists suggest using the whitening kit every day for a week after the in-office procedure. Based on your case and your expectations, you may or may not be given an at-home bleaching tray.
- Wine
- Coffee or tea
- Fruits (except for banana)
- Beets
- Chocolate
- Acidic foods
After teeth whitening, your teeth could get relatively more sensitive than before. It is helpful to use special toothpaste that is made to reduce tooth sensitivity. To prevent discomfort in your teeth, you should also avoid foods that are too hot or too cold.
A practical point for your care
Before an operation, the pre-assessment team should review your health, previous tests and all medicines and supplements. Ask for written instructions on medicines, eating, drinking and aftercare that apply to your planned procedure.[1]
