Achieving a Dazzling Smile: The Science Teeth Whitening
Methods and Their Effectiveness
In our quest for a captivating and radiant smile, we often turn to teeth whitening as the solution. Yet, despite our eagerness for
brighter teeth, the mechanics behind the teeth whitening process often elude us. Understanding the intricacies of this procedure,
including the ingredients present in various whitening agents, is crucial for making informed decisions. As consumer demand for
teeth whitening products surges, evidenced by a survey conducted by the American Academy of Cosmetic Dentistry (AACD)
revealing that 96% of adults believe an attractive smile enhances one’s appeal, it becomes increasingly important to delve deeper
into the world of teeth whitening.
Types of stains and their whitening techniques
- Various types of stains can manifest on the surfaces of teeth. Some are superficial, such as those caused by tea, coffee, soda, or wine. In such instances, whitening paste, trays, or strips may prove effective. However, certain stains penetrate deeper layers. For example, tobacco stains often require a more intensive whitening approach. Professional chair-side whitening procedures are tailored to address such deep-seated stains effectively. In this blog, we will comprehensively explore different whitening techniques and their respective formulations.
There are two primary types of teeth whitening methods:
- Non-bleachin
- Bleaching.
- Non-bleaching methods, such as toothpaste or teeth polishing, rely on physical action to remove stains from the surface of the teeth. On the other hand, bleaching agents utilize chemicals to break down stains and lighten the color of the teeth.
- In this discussion, we’ll delve into the various forms of teeth whitening products to gain a better understanding of their differences and effectiveness.
Teeth whitening paste.
- These pastes may not have a deep-reaching effect, but they are highly convenient due to their easy availability and ease of use. Whitening toothpaste achieves teeth whitening through regular brushing, as it contains more abrasive agents that effectively remove surface stains.
Scaling and polishing teeth.
- Scaling and polishing are performed by dental professionals to remove external stains. During this procedure, polishing cups and brushes are utilized along with prophylactic paste. This physical process effectively scrubs away stains, utilizing friction to achieve stain removal. While this procedure may not result in visibly whiter teeth, it significantly enhances cleanliness and polish.

Laser treatment for teeth whitening
- This treatment is typically administered at a dental clinic due to its costliness. Using laser light, this procedure effectively breaks down stained molecules to facilitate easy stain removal. A whitening gel is applied to the teeth, followed by exposure to the laser light, which activates the whitening properties and modifies the stained molecules of the teeth
- It’s common to experience some sensitivity for up to 24 hours following this procedure
Micro abrasions
- This technique involves the removal of surface enamel through both erosive and abrasive effects on the teeth. As a result, this treatment is typically reserved for cases where stains are internal or when teeth exhibit enamel defects such as enamel hypoplasia, enamel hyper mineralization, hypo-mineralization, or other conditions.
- During this procedure, a low-speed motor is utilized along with a hydrochloric acid gel. This process typically removes between 20 to 200 micrograms of enamel. Consequently, fluoride treatment is often recommended following micro-abrasion therapy to help protect and strengthen the remaining enamel.
- Below are pictures illustrating the micro-abrasion treatment of individuals with enamel defects.
Teeth whitening strips and mouthwash
- Teeth whitening strips typically contain between 5% to 14 % hydrogen peroxide. An adhesive agent within the strips gradually releases the active bleaching agent after approximately 6-8 minutes of application. Patients are generally advised to keep the strips in place for at least 15 minutes to ensure optimal whitening results.
- Teeth whitening mouthwashes typically contain a low concentration of hydrogen peroxide, usually around 1.5%. However, despite its convenience, it is often considered less effective compared to other forms of whitening products such as whitening toothpaste or whitening strips.
Teeth whitening products. (In office)
- These professional teeth whitening products typically contain a high concentration of hydrogen peroxide, ranging from 35% to 40%. Administered at dental clinics under professional supervision, a gel form of hydrogen peroxide is applied to the teeth for 15-20 minutes per session. This process can be repeated as needed until the desired results are achieved, with the number of cycles determined by your dentist.
- The primary chemical agent in these products is hydrogen peroxide. Upon contact with the enamel, hydrogen peroxide breaks down into oxygen and water. The remaining oxygen molecules penetrate the enamel and react with the molecules of the discolored material, breaking them down. This mechanism is how these products effectively remove stains.
Phillips Zoom teeth whitening
- Offers a unique feature of special LED blue light, which accelerates the whitening agents to achieve whiter teeth more effectively. Moreover, various modes of this light are available to ensure a more comfortable experience during the procedure. Each cycle lasts for 15 minutes, and the treatment can be repeated for up to 3 cycles to attain the desired results.

- Here, we have before and after pictures of one of our patients who underwent Phillips Zoom teeth whitening. You can observe the shade difference in the pictures, with the teeth appe aringlighter after the treatment.
Home bleaching products.
- Low-concentration hydrogen peroxide (14%) is utilized for at-home bleaching treatments. You can request your dentist to create trays for you, allowing you to perform bleaching conveniently at home
- Another bleaching material commonly used is carbamide peroxide, with concentrations ranging from 10% to 16%. This too can be employed for at-home bleaching procedures.
- With the correct technique, you can achieve a brighter smile, lightening your teeth by two to three shades.
In conclusion
- Achieving a brighter smile is possible with the range of teeth whitening options available. Understanding the science behind these treatments empowers you to make informed decisions. Whether you opt for professional treatments or at-home methods, the goal remains the same: a confident and radiant smile.
