Tooth whitening has become one of the most frequently requested dental procedures by the public. The public has come to demand whiter, more perfect smiles and in response many choices for tooth whitening have been made available. These include home-based products such as toothpastes, gels, and films, as well as in-office based systems where products containing highly concentrated bleaching agents are applied under professional supervision. The profession and public have been aware of certain risks related to tooth whitening such as increased tooth sensitivity and gingival irritation. New research has shown that there are other risks such as tooth surface roughening and softening, increased potential for demineralization, degradation of dental restorations, and unacceptable color change of dental restorations. The new research is also focused on optimizing whitening procedures to reduce tooth sensitivity and to increase the persistence of the whitening.

The public has been influenced by the portrayal of perfect white smiles in the media. . The color quality of television, movies, electronic and print media has raised self-awareness of discolored teeth. In the late &#;s several companies introduced both home-based products and professionally applied tooth whitening products into the U.S. marketplace. These have gained popularity with the public who has come to demand whiter, more perfect smiles.1 There are several different methods for whitening teeth, each with their own mechanism of action. The efficacy of these different methods is dependent upon the particular tooth discoloration that is being treated. Causes of tooth discoloration can be categorized into two main groups: intrinsic and extrinsic staining (see ). Intrinsic staining, sometimes called internal staining, can be attributed to factors such as genetics, age (from enamel wear over time exposing yellower dentin), antibiotics, high levels of fluoride, and developmental disorders and can start before the tooth has erupted. After eruption of the tooth some dental restorations can cause tooth staining. Extrinsic staining, sometimes called external staining, is largely due to environmental factors including smoking,pigments in beverages and foods, antibiotics, and metals such as iron or copper. Colored compounds from these sources are adsorbed into acquired dental pellicle or directly onto the surface of the tooth causing a stain to appear. See for examples of the staining from these sources.
Tooth whitening is any process that lightens the color of a tooth. Whitening may be accomplished by physical removal of the stain or a chemical reaction to lighten the tooth color. Bleaching is defined here as the chemical degradation of the chromogens. The active ingredient in most whitening products is hydrogen peroxide (H2O2) which is delivered as hydrogen peroxide or carbamide peroxide. Carbamide peroxide is a stable complex that breaks down in contact with water to release hydrogen peroxide. Because carbamide peroxide releases hydrogen peroxide the chemistry of most tooth whitening is that of hydrogen peroxide.
Tooth stains consist of compounds that have color or darker shades called chromogens that are accumulated in the tooth (intrinsic) or on the tooth (extrinsic). Chromogens fall into two categories: large organic compounds that have conjugated double bonds in their chemical structure as shown in ; and metal containing compounds. Bleaching of the organic compounds by hydrogen peroxide involves reacting with the double bonds to oxidize the double bond as shown in . This causes the chromogen to become a lighter colored compound. Bleaching of the metallic compounds is much more difficult; better esthetic options may be veneers, bonding, or crowns. There are some professional products that contain sodium hypochlorite (NaOCl) which reacts with the double bonds of the chromogen in much the same way as peroxide as shown in .
Open in a separate windowDifferent product types are marketed to address the particular stain to be removed. The broad categories include: cleansers such as smokers&#; toothpastes which contain larger amounts of detergents and abrasives to aid in the removal of chromogens from the tooth surfaces; bleaches to react with the chromogens to lighten color; and products that have both increased cleansing and bleaching. More severe or complex stains are best lightened professionally, while over-the-counter products can be used for milder cases. The treatment time required for reaching the tooth whitening end point is dependent on the time of exposure and the concentration of bleaching compound. This end point is dependent on the type of whitening employed, usually 1 to 2 shades for cleansers and over-the-counter (OTC) gels, and more for professionally applied products.
Hydrogen peroxide teeth whitening gel works by releasing oxygen that penetrates the surface of the teeth to remove deep-set stains and discoloration. The oxygen molecule penetrates the pores of the enamel and dentin, breaking down the organic compounds that cause discoloration. The gel should be applied to the surface of the teeth, typically with a mouthguard or tray, and left on for a specified amount of time before being removed. The process may need to be repeated multiple times for desired results.
Teeth whitening technicians should consider carrying teeth whitening gel pens as part of their inventory. With the growing popularity of DIY teeth whitening and aftercare among consumers, technicians can capitalize on this trend by stocking up on the latest teeth whitening products. Furthermore, adding these items to their portfolio can attract new customers who are looking for convenient and affordable whitening solutions.
Teeth whitening gel is a safe and gentle way to achieve the desired white teeth without harsh chemicals. It comes in both pens, syringes or with a professional grade tray that can be used with a teeth whitening accelerator machine. With teeth whitening gel when combined with a professional teeth whitening LED lamp can achieve up to five to fourteen shades whiter than your current shade. The active ingredient in the gel is hydrogen peroxide, which helps break down surface stains caused by everyday activities such as drinking coffee and eating foods like curry.
Hydrogen peroxide and carbamide peroxide are both commonly used active ingredients in teeth whitening products.
Hydrogen peroxide (H2O2) is a strong oxidizing agent that releases oxygen to whiten teeth. It works by breaking down organic compounds that cause discoloration, which can penetrate deep into the enamel and dentin.
Carbamide peroxide (C6H10O5) is a compound that contains hydrogen peroxide and urea. When carbamide peroxide is applied to the teeth, it breaks down into hydrogen peroxide and urea, releasing oxygen that whitens the teeth.
In terms of effectiveness, hydrogen peroxide is considered to be faster-acting compared to carbamide peroxide, as it releases oxygen more quickly. However, carbamide peroxide is more stable and has a longer shelf life than hydrogen peroxide, which can make it a more popular choice for at-home whitening products.
For in-chair teeth whitening, hydrogen peroxide is the more popular choice, as it is faster-acting and can produce noticeable results in a single session. However, the concentration of hydrogen peroxide used in in-chair whitening treatments is higher than what is found in over-the-counter products, so it&#;s important to follow the instructions provided by a professional supplier and to talk to your dentist before undergoing in-chair whitening treatment.
A 6% hydrogen peroxide solution is equivalent in strength to a 18% carbamide peroxide solution. The concentration of hydrogen peroxide released from carbamide peroxide can be determined by converting the carbamide peroxide concentration into an equivalent hydrogen peroxide concentration using a simple formula. A common conversion rate is 1 part carbamide peroxide equaling 3 parts hydrogen peroxide.
Therefore, 18% carbamide peroxide is equivalent to 6% hydrogen peroxide in terms of strength. The concentration of hydrogen peroxide or carbamide peroxide in a product will determine the strength of the product, and both active ingredients can be effective in whitening teeth when used as directed.
It&#;s important to note that higher concentrations of hydrogen peroxide or carbamide peroxide may not necessarily lead to better results, and can also increase the risk of tooth sensitivity or other adverse effects. It&#;s recommended to talk to a professional supplier before using any whitening products to ensure safe and effective use.
To ensure the best storage for peroxide teeth whitening gel, it is recommended to follow these guidelines:
Temperature: Store the whitening gel in a cool, dry place, away from direct sunlight and heat sources. Extreme temperatures can cause the active ingredients, such as hydrogen peroxide or carbamide peroxide, to break down and become less effective.
Expiry date: Check the expiry date of the whitening gel and do not use it past this date. Over time, the active ingredients can break down, making the gel less effective.

Storage conditions: Keep the whitening gel in its original packaging and make sure it is tightly sealed when not in use. This will help to prevent the gel from drying out and losing its effectiveness.
It&#;s important to follow the manufacturer&#;s instructions for storing and using the whitening gel, as some products may have specific requirements or recommendations. If you have any concerns or questions about storing the whitening gel, it&#;s best to talk to a professional supplier.
