“Pure Smile Natural” – Teeth Whitening 2.0


Professional Teeth whitening is fulfilling and sought after dental procedure meant to improve the smile contrast with the other aesthetic facial features. It has been practiced even by the ancient Egyptians, as a method of influencing the social interactions by communicating health, beauty, and affluence. At first glance, it seems to be a rather aggressive procedure, making use of powerful oxygen-releasing substances – peroxide. Many patients are expressing their concerns about it, also due to the rumor that is painful. In my over 18 years of experience in using multiple bleaching systems (Laser, Blue Light, Trays, Strips…) both in USA and Germany,

… Teeth can be damaged if the procedure is NOT done properly or with home bleaching kits.

Yes, you were right to be afraid of bleaching because it can damage the enamel. In the same time, teeth whitening can be very beneficial for the teeth. How can that be?! Let’s see first how bleaching teeth works.

How is Teeth Whitening working?

The professional procedure involves powerful peroxide-based gels placed only on enamel. They remove all the surface stains through oxygenation and brake down the chromophores’ bond to large, dark molecules inside the enamel. Meanwhile, the superficial minerals are also extracted, giving the teeth a more opaque appearance. After bleaching, teeth are more susceptible to stains and scratches. However, if Carbamide Peroxide bleaching is used – which a is buffered solution of Hydrogen Peroxide, and immediately after the procedure, the teeth are remineralized with high quality, fluoride-bonded calcium than the enamel becomes Stronger than before the Bleaching! The first research on this subject was initiated in Japan at the Showa University in Tokyo, where they found that In-Office bleaching is much more beneficial to the tooth structure than at-home bleaching due to a better remineralization pattern and consequent stronger enamel resistance against mouth acids.

What “speaks” against Teeth Whitening?

Caries, enamel cracks, excessive biofilm, and tartar, periodontal disease with recessed gums – root surface exposure might give a lot of sensitivity if not properly covered. In other words, before considering teeth whitening, a thorough dental exam is necessary. For the best results and minimum sensitivity, the procedure type and the sequencing of teeth whitening with other dental procedures need to be individualized.

Which are the benefits of Teeth Whitening?

The most powerful effect is the contrast enhancement of the smile in relation to the other facial features. Depending on the type of complexion, eyes color, white of the eyes, lip form, hair color, the newly bleached shade can be anywhere between very dominant (darker skin, dark eyes, and hair) to nicely integrated with the face (fair skin, blue eyes, blonde hair). Bleaching provides a distinctively brighter smile which thereafter only with the Pure White Natural protocol can be toned to a shade that fits best one’s aesthetic outlook. The emotional gain is immense and the social benefits are considerable.

In the same time, with the remineralization protocol, the teeth gain a newly-infused high-quality mineral layer, which makes them stronger against acidic foods or drinks.

It is important to know that teeth whitening is not permanent. The tooth shde will come back over time (in months or years) to the original tooth color. It is not possible to Permanently brighten the color of the teeth with teeth whitening. That can be achieved only with the Pure White Custom protocol (custom made porcelain veneers).

In conclusion, tooth whitening is a safe and beneficial procedure as long as it is done with products chosen specifically for your needs and while the dentist is designing the appropriate protocol for bleaching, remineralization and shade maintenance/toning.
