Not Recommended For Teeth Whitening
● Tetracycline staining
● Mild fluorosis

Duration Of Operation
30 to 60 minutes
Teeth whitening, also known as dental bleachingor tooth whiteningis a very common cosmetic dentistry procedure. There is a small difference between whitening and bleaching – bleaching is used to whiten teeth beyond their natural color while whitening restores the natural color of the teeth. In 2010, more than 100 million teeth whitening procedures were performed in the USA alone, making it one of the most popular cosmetic dentistry procedures in the world.
Dental bleaching can be applied through different techniques:
● Teeth whitening laser
● Teeth whitening gel
● Bleaching pen
● Teeth whitening strips
Dental bleaching uses hydrogen peroxide or carbamide peroxide to whiten or bleach the teeth. This special solution infiltrates the teeth’s enamel and breaks away any stains.

● Genetic factors
● Tetracycline-based antibacterial drugs
● Enamel hypoplasia
● Poor oral hygiene

● Chlorhexidine – this substance is often used in toothpaste and mouthwash
Patients need to stop smoking before the teeth whitening procedure and then quit altogether
How It Is Performed
A teeth whitening procedure is a simple cosmetic dentistry treatment which can refurbish discolored teeth. The procedure is safe and straightforward, which minimal risks involved.
The teeth whitening dentist will first apply a unique solution on the patient's gums – this is a chemical barrier that will protect the gums during the teeth whitening procedure.
The teeth whitening dentist will then proceed to apply the whitening solution on to the teeth – this is a bleach-based solution, specifically designed for dental work and dental restoration.
Once the solution is applied, the teeth whitening dentist will use a combination of light and heat to activate it, effectively removing any stains from the teeth’s enamel. Once this part of the procedure is finished, the area is cleaned and repeated two more times. When the desired result is achieved, the teeth whitening dentist will remove the barrier applied on the gums and the patient may return home.
Teeth that previously underwent root canal treatment may have the teeth whitening solution injected deep into the roots for a better result.
The teeth whitening procedure does not require any recovery period. Patients may fly, drive, and resume normal activities immediately.y.
Teeth whitening complications can include one or more of the following:
● Chemical burns from the whitening solution
● Increased teeth sensitivity to hot or cold stimuli
● Bleachorexia – the patient, can become obsessed with whitening

Before And After
Most individuals report feeling more confident and more comfortable in social settings after the procedure is done. It’s important to note that teeth whitening or dental bleaching does not offer permanent results. Patients will be required to avoid certain drinks or types of food after the treatment in order to maintain the results. Some individuals generally opt for another teeth whitening procedure in around ten to twelve months after the first one.
Patients who consume plenty of staining foods such as sodas or coffee may require another procedure in just a couple of months. One of the biggest factors when it comes to staining teeth is smoking, as the tar found in cigarettes will stick to the tooth's enamel. It is this tar that darkens the teeth – brushing will not remove it either. As such, patients will have to alter their lifestyles in order to maintain their new smile for longer periods of time.
Is dental bleaching painful?
Not – patients don't feel a thing.
Is teeth whitening safe?
Teeth whitening does not affect the health of the patient’s teeth in any way. The procedure itself is very popular among patients as well as dentists.
Can dental bleaching damage fillings, crowns or bridges?
No, but they may need replacing for a more consistent look.
Do teeth whitening strips work?
Teeth whitening strips may work to some degree – it all depends on the type of staining the tooth has and its depth. That being said, teeth whitening strips do not offer the same results as a procedure performed by a professional dentist.
Laser Teeth Whitening
Laser Teeth Whitening, also known as light accelerated bleaching uses different types of light energy such as plasma arc, LED or halogen in order to accelerate the bleaching process. While the addition of different energy sources makes the procedure faster, it does not improve the overall results by a great deal.
Naoparticle Catalysts combined with hydrogen peroxide
While it is a relatively new technique, titanium oxide-based catalysts can be used with a solution with lower levels of hydrogen peroxide. This technique is mostly applied for patients with very sensitive teeth since it has the advantage of lowering overall side effects while maintaining great overall results.
Teeth which had their nerves removed through a root canal treatment tend to get darker and darker as time passes. Internal bleaching can be applied to these teeth in order to maintain them the same color or shade as the patient's other teeth. This type of teeth whitening is performed by introducing the bleaching solution inside the teeth itself and regularly replacing it until the perfect color is achieved.
