Teeth whitening is a popular cosmetic procedure that many people seek to enhance their smile. This process involves various methods and materials used by dentists to achieve brighter, whiter teeth. In this article, we will explore what dentists use to bleach teeth, including the types of products and techniques available. We will also discuss the science behind teeth whitening and the safety measures involved.
Understanding Teeth Whitening
Teeth whitening, also known as dental bleaching, is a procedure designed to lighten the color of teeth and remove stains. Over time, teeth can become discolored due to factors like aging, food and drink consumption, and smoking. Teeth whitening treatments help restore a more youthful appearance and improve overall dental aesthetics.
Common Teeth Whitening Agents
Dentists use several agents for teeth whitening. These agents primarily include hydrogen peroxide and carbamide peroxide. Each agent works differently but aims to achieve the same result—whiter teeth.
Hydrogen Peroxide
Hydrogen peroxide is a common bleaching agent used in professional teeth whitening. It is a strong oxidizing agent that breaks down the molecules causing stains. This process helps to lighten the color of the teeth.
Hydrogen peroxide is often used in higher concentrations in professional treatments compared to over-the-counter products. Dentists apply hydrogen peroxide in a controlled environment to ensure safety and effectiveness.
Carbamide Peroxide
Carbamide peroxide is another popular bleaching agent. It is a compound that breaks down into hydrogen peroxide when it comes into contact with moisture. This reaction provides the whitening effect on teeth.
Carbamide peroxide is used in various concentrations depending on the type of treatment. It is commonly used in take-home whitening kits provided by dentists. Carbamide peroxide is effective in gradually whitening teeth over a more extended period.
Professional In-Office Whitening Treatments
Dentists offer several in-office whitening treatments that use different techniques and products. These treatments are designed to provide quick and noticeable results.
Zoom Whitening
Zoom whitening is a popular in-office treatment that uses a combination of hydrogen peroxide gel and a special light. The process involves applying the gel to the teeth and then using the light to accelerate the whitening effect.
The treatment typically lasts about an hour and can lighten teeth several shades in just one session. Zoom whitening is known for its effectiveness and quick results.
Opalescence Boost
Opalescence Boost is another in-office whitening treatment that uses a high-concentration hydrogen peroxide gel. This treatment is applied to the teeth in a controlled environment.
Opalescence Boost does not require the use of a light, making it a convenient option for many patients. The procedure generally takes about an hour and provides immediate results.
Laser Whitening
Laser whitening is a procedure that uses a laser to enhance the effects of a bleaching agent. The dentist applies a bleaching gel to the teeth and then uses a laser to activate the gel and speed up the whitening process.
Laser whitening treatments are known for their effectiveness and quick results. The procedure is often completed within an hour and can produce significant whitening effects.
Take-Home Whitening Kits
Dentists also provide take-home whitening kits for patients who prefer to whiten their teeth at home. These kits include custom-made trays and bleaching agents.
Custom Trays
Custom trays are made from impressions of a patient’s teeth. These trays ensure that the bleaching gel is evenly distributed and stays in contact with the teeth for optimal results.
Whitening Gel
The whitening gel used in take-home kits typically contains either hydrogen peroxide or carbamide peroxide. The concentration of the gel is usually lower than that used in in-office treatments.
Patients apply the gel to the custom trays and wear them for a specified period, usually a few hours a day or overnight. The treatment duration varies depending on the product and desired results.

Over-the-Counter Whitening Products
In addition to professional treatments, there are numerous over-the-counter whitening products available. These products are generally less potent than those used by dentists but can still be effective.
Whitening Toothpastes
Whitening toothpastes contain mild abrasives and chemical agents that help remove surface stains. They do not change the color of the teeth significantly but can help maintain a brighter appearance.
Whitening Strips
Whitening strips are thin, flexible plastic strips coated with a whitening gel. The strips are applied to the teeth for a specified period, usually 30 minutes to an hour. They can be effective in lightening teeth by a few shades.
Whitening Gels
Whitening gels are applied directly to the teeth using a brush or applicator. These gels contain peroxide-based bleaching agents and can provide noticeable results over time.
Teeth Whitening Pens
Teeth whitening pens are small, portable devices that allow for targeted application of a whitening gel. They are convenient for spot treatments and on-the-go use.
The Science Behind Teeth Whitening
Teeth whitening works through a process called oxidation. Oxidizing agents like hydrogen peroxide and carbamide peroxide break down the molecules responsible for staining teeth. This reaction lightens the color of the teeth and improves their overall appearance.
Safety Considerations
While teeth whitening is generally safe, it is essential to follow safety guidelines and recommendations provided by dental professionals.
Sensitivity
One common side effect of teeth whitening is increased tooth sensitivity. This sensitivity occurs due to the bleaching agents penetrating the tooth enamel and affecting the nerves. It is usually temporary and subsides after the treatment.
Gum Irritation
Gum irritation can occur if the bleaching agents come into contact with the gums. Dentists use protective barriers to minimize this risk during professional treatments. Patients should follow instructions carefully when using take-home kits to avoid gum irritation.
Long-Term Effects
Long-term effects of teeth whitening are generally minimal. However, it is essential to maintain good oral hygiene and avoid excessive consumption of stain-causing substances to prolong the results.
Maintaining Whitened Teeth
To maintain the results of teeth whitening treatments, it is crucial to practice good oral hygiene and make lifestyle adjustments.
Regular Brushing and Flossing
Regular brushing and flossing help remove plaque and prevent new stains from forming. Using a fluoride toothpaste can also help protect enamel and maintain a bright smile.
Avoiding Stain-Causing Foods and Drinks
Limiting consumption of stain-causing foods and drinks, such as coffee, tea, and red wine, can help preserve the whiteness of teeth. Rinsing the mouth with water after consuming these substances can also reduce their staining effects.
Regular Dental Checkups
Regular dental checkups allow for professional cleanings and monitoring of oral health. Dentists can provide touch-up treatments if necessary and address any issues that may affect the appearance of teeth.
Conclusion
In summary, dentists use various agents and techniques to bleach teeth, including hydrogen peroxide, carbamide peroxide, and different in-office treatments. Teeth whitening is an effective way to enhance the appearance of your smile, but it is essential to follow safety guidelines and maintain good oral hygiene. Whether opting for professional treatments or over-the-counter products, understanding what dentists use to bleach teeth can help you make informed decisions about achieving a brighter, whiter smile.
