Teeth whitening is one of the most sought-after cosmetic dental procedures. A bright, white smile is often associated with youth and beauty, making whitening treatments a popular choice among patients. Many people turn to over-the-counter products like whitening strips and gels, but professional treatments provided by dentists use stronger, more effective whitening gels. In this article, we will explore what whitening gels dentists use, how they work, and why they are a better option than at-home alternatives.
Understanding Teeth Whitening Gels
Teeth whitening gels are solutions that contain active ingredients designed to break down stains on the surface of the teeth and lighten the overall shade. The most common active ingredient in whitening gels is hydrogen peroxide or carbamide peroxide. These agents are capable of penetrating the enamel, where they break down the molecules responsible for staining. Whitening gels used by dentists are typically much stronger than those found in over-the-counter products, making them more effective at achieving noticeable results in a shorter amount of time.
Hydrogen Peroxide vs. Carbamide Peroxide
Two key ingredients used in professional teeth whitening gels are hydrogen peroxide and carbamide peroxide. Both are effective bleaching agents, but they differ slightly in how they work.
Hydrogen Peroxide: This is the more commonly used bleaching agent in whitening gels. It works by releasing oxygen molecules that break down the pigment molecules responsible for tooth discoloration. Hydrogen peroxide is faster-acting and generally produces quicker results, but it can also be more irritating to sensitive teeth and gums if not used properly.
Carbamide Peroxide: This compound is a combination of urea and hydrogen peroxide. It breaks down into hydrogen peroxide when it comes into contact with the tooth surface, but it does so more slowly than pure hydrogen peroxide. This slower reaction can make carbamide peroxide a gentler option for some patients. It is often used in professional at-home whitening kits prescribed by dentists.
Whitening Gels Used by Dentists
Dentists have access to professional-grade whitening gels that are much stronger than over-the-counter options. These gels typically have higher concentrations of hydrogen peroxide or carbamide peroxide, ranging from 15% to 43% in strength, compared to the 3% to 10% strength found in many over-the-counter products.
Zoom! Whitening Gel
One of the most popular professional whitening treatments offered by dentists is the Zoom! whitening system. Zoom! uses a hydrogen peroxide-based gel that is applied directly to the teeth. The gel is activated by a special light, which accelerates the whitening process and helps it work more effectively. The process typically takes about an hour and results in dramatic whitening.
Zoom! whitening gel is known for producing fast results with minimal discomfort. Many patients experience little to no sensitivity during the procedure, although some may feel a slight tingling sensation. Zoom! whitening is effective for treating a wide range of stains, including those caused by aging, tobacco, coffee, and other common staining agents.
Opalescence Whitening Gel
Opalescence is another popular professional whitening gel used by dentists. This gel comes in various formulations, including those for in-office treatments and take-home whitening kits. Opalescence gels contain carbamide peroxide, which releases hydrogen peroxide over time. This makes Opalescence a good option for patients with sensitive teeth.
Opalescence whitening gel is known for its ability to provide long-lasting results. It’s available in different concentrations, with higher concentrations producing faster results. For patients seeking a more gradual whitening process, Opalescence also offers lower concentrations that are gentler on the teeth and gums.
KöR Whitening Gel
KöR is a professional teeth whitening system that uses a unique whitening gel, formulated with high levels of hydrogen peroxide. This system is especially effective for people who have severe tooth discoloration or staining that has developed over many years. KöR whitening gel is applied in-office for optimal results but can also be used as part of a take-home treatment.
One of the advantages of KöR whitening gel is its ability to whiten teeth effectively, even for people who have experienced tooth sensitivity with other treatments. The gel is designed to be more stable and longer-lasting than other whitening products, making it a great choice for patients who have had disappointing results with other systems.
Sapphire Whitening Gel
Sapphire is another professional whitening system offered by some dentists. It uses a high-concentration hydrogen peroxide gel that is applied to the teeth during a single office visit. Sapphire is known for delivering fast, dramatic results, often whitening teeth by several shades in just one session.
The Sapphire whitening system also includes the use of a special light that helps activate the whitening gel and speeds up the bleaching process. This system is effective for patients with moderate to severe staining, and it provides noticeable results after a single visit.
Why Do Dentists Use Stronger Whitening Gels?
The main reason dentists use stronger whitening gels is that they can produce more significant and faster results. Professional treatments are often more effective than over-the-counter products because the gels used by dentists have higher concentrations of hydrogen peroxide or carbamide peroxide. These stronger formulations allow for deeper penetration of the tooth enamel, which results in more thorough removal of stains and a more noticeable improvement in tooth color.
Additionally, in-office whitening treatments are performed by dental professionals who can ensure the gel is applied properly and safely. They can also protect the gums and soft tissues of the mouth during the procedure, minimizing the risk of irritation or damage.
Speed and Effectiveness
One of the main advantages of professional whitening gels is the speed with which they work. A typical in-office whitening session can take as little as one hour, and patients often see immediate results. This is in contrast to over-the-counter products, which may take several days or even weeks to show significant improvements.
The whitening gels used by dentists are also more effective at treating deep or stubborn stains that may not be affected by lower-concentration products. Whether the stains are caused by coffee, wine, smoking, or aging, professional whitening gels are typically more capable of producing a noticeable change in tooth color.
Safety and Customization
When you receive teeth whitening treatment from a dentist, the whitening gel is carefully applied, and your dentist can monitor your progress to ensure your comfort and safety throughout the process. For example, some people experience tooth sensitivity or gum irritation during whitening, and a dentist can make adjustments to reduce these issues.
In contrast, over-the-counter products may not offer the same level of customization or attention. They may not be as effective for individuals with sensitive teeth or specific dental needs.
Potential Side Effects of Whitening Gels
Although professional whitening gels are generally safe when used as directed, there are some potential side effects that patients should be aware of. These can include:
Tooth Sensitivity
Many people experience tooth sensitivity after whitening treatments. This is due to the active ingredients, such as hydrogen peroxide, temporarily weakening the enamel. This sensitivity typically subsides after a few hours, but some people may experience lingering discomfort.
Gum Irritation
If the whitening gel comes into contact with the gums, it can cause temporary irritation or inflammation. Dentists take special precautions to avoid this, but some patients may still experience mild irritation.
Uneven Whitening
In some cases, professional whitening gels may not produce uniform results. Stains that are deeply embedded in the teeth may not lighten as evenly as the surrounding areas, leading to blotchy or uneven whitening.
Conclusion
Professional whitening gels used by dentists are more potent and effective than over-the-counter alternatives. These gels, such as Zoom!, Opalescence, KöR, and Sapphire, are designed to provide faster, more noticeable results, with the added benefit of being carefully administered by a trained professional. While there are potential side effects like tooth sensitivity and gum irritation, these are typically mild and temporary. For those looking to achieve a bright, beautiful smile, professional whitening treatments may be the best option, offering more dramatic and long-lasting results than at-home treatments. Always consult with your dentist before undergoing any whitening procedure to determine which treatment is best suited to your needs.
