Teeth whitening is a popular cosmetic dental procedure that many people seek to achieve a brighter smile. While there are many over-the-counter products available, professional teeth whitening treatments performed by dental experts are often more effective and safer. In this article, we will explore what professionals use to whiten teeth, the different methods available, and how they work.
Understanding Teeth Discoloration
Before diving into the methods professionals use to whiten teeth, it’s important to understand why teeth become discolored in the first place. Teeth can become stained or discolored due to various reasons, including:
Food and Drinks:
Coffee, tea, red wine, and certain foods like berries can stain teeth.
Tobacco Use:
Smoking or chewing tobacco can cause yellowing of the teeth.
Aging:
As we age, the outer layer of enamel on our teeth wears away, revealing the naturally yellow dentin underneath.
Medications:
Certain medications, such as tetracycline, can cause tooth discoloration.
Poor Oral Hygiene:
Not brushing and flossing regularly can lead to plaque buildup and staining.
Understanding the cause of discoloration helps dental professionals choose the most effective whitening treatment.
Professional Teeth Whitening Methods
Dental professionals use several methods to whiten teeth, each with its own advantages. The most common professional teeth whitening methods include:
In-Office Whitening
In-office whitening is one of the most popular and effective methods for achieving a brighter smile. This procedure is performed by a dental professional in a controlled environment, ensuring safety and effectiveness.
How It Works
Preparation:
The dentist will start by cleaning your teeth to remove any plaque or debris. They will then protect your gums and lips with a barrier to prevent irritation from the whitening agent.
Application:
A high-concentration hydrogen peroxide or carbamide peroxide gel is applied to the teeth. This gel is much stronger than what you would find in over-the-counter products.
Activation:
Some in-office whitening treatments use a special light or laser to activate the whitening gel, speeding up the process.
Rinsing:
After the desired shade is achieved, the gel is rinsed off, and the teeth are polished.
Advantages
Fast Results:
You can see results in just one visit, often within an hour.
Professional Supervision:
The procedure is performed by a trained professional, reducing the risk of side effects.
Customization:
The dentist can tailor the treatment to your specific needs.
Take-Home Whitening Kits
Take-home whitening kits are another option provided by dental professionals. These kits allow you to whiten your teeth at home, but with the guidance and supervision of your dentist.
How It Works
Custom Trays:
Your dentist will take impressions of your teeth to create custom-fitted trays. These trays ensure that the whitening gel is evenly distributed and stays in contact with your teeth.
Whitening Gel:
You will be given a professional-grade whitening gel, usually containing a lower concentration of hydrogen peroxide or carbamide peroxide compared to in-office treatments.
Application:
You will fill the trays with the gel and wear them for a specified amount of time each day, usually for a couple of hours or overnight.
Duration:
The treatment typically lasts for one to two weeks, depending on the desired level of whitening.
Advantages
Convenience:
You can whiten your teeth at home on your own schedule.
Custom Fit:
The custom trays ensure even application and reduce the risk of gum irritation.
Professional Guidance:
Your dentist will monitor your progress and provide instructions for optimal results.
Laser Teeth Whitening
Laser teeth whitening is a more advanced form of in-office whitening that uses laser technology to enhance the whitening process.
How It Works
Preparation:
Similar to in-office whitening, the dentist will clean your teeth and protect your gums and lips.
Application:
A high-concentration whitening gel is applied to the teeth.
Laser Activation:
A laser is used to activate the whitening gel, breaking down the stains more effectively.
Rinsing:
The gel is rinsed off, and the teeth are polished.
Advantages
Quick Results:
Laser whitening can produce noticeable results in just one session.
Enhanced Effectiveness:
The laser helps the whitening gel penetrate deeper into the enamel, removing more stubborn stains.
Professional Supervision:
The procedure is performed by a trained professional, ensuring safety and effectiveness.
Veneers and Bonding
In some cases, teeth whitening may not be sufficient to achieve the desired results, especially if the discoloration is severe or due to intrinsic factors. In such cases, dental professionals may recommend veneers or bonding.
Veneers
What They Are:
Veneers are thin shells made of porcelain or composite resin that are custom-made to fit over the front surface of your teeth.
How They Work:
The dentist will remove a small amount of enamel from the front of your teeth and then bond the veneers in place. Veneers can be made to match the color of your natural teeth or to create a whiter, brighter smile.
Advantages:
Veneers are highly durable and resistant to staining. They can also correct other cosmetic issues, such as chips or gaps.
Bonding
What It Is:
Bonding involves applying a tooth-colored resin to the surface of the teeth and then hardening it with a special light.
How It Works:
The dentist will apply the resin to the teeth, shape it to achieve the desired look, and then harden it. Bonding can be used to cover stains, chips, or gaps.
Advantages:
Bonding is a less invasive and more affordable option compared to veneers. It can be completed in a single visit.
Safety and Side Effects
While professional teeth whitening is generally safe, it’s important to be aware of potential side effects and take precautions.
Common Side Effects
Tooth Sensitivity:
Some people may experience increased tooth sensitivity during or after the whitening process. This is usually temporary and can be managed with desensitizing toothpaste or gels.
Gum Irritation:
The whitening gel can sometimes irritate the gums, causing redness or discomfort. This is more common with over-the-counter products but can occur with professional treatments if the gums are not properly protected.
Uneven Whitening:
In some cases, teeth may whiten unevenly, especially if there are restorations like fillings or crowns that do not respond to whitening agents.
Precautions
Consultation:
Always consult with your dentist before undergoing any whitening treatment to ensure it is safe for your teeth and gums.
Follow Instructions:
If using a take-home kit, follow your dentist’s instructions carefully to avoid overuse or misuse of the whitening gel.
Avoid Staining Agents:
After whitening, avoid foods and drinks that can stain your teeth, and maintain good oral hygiene to prolong the results.
Maintaining Your Whitened Teeth
After undergoing a professional teeth whitening treatment, it’s important to take steps to maintain your bright smile.
Tips for Maintaining Whitened Teeth
Brush and Floss Regularly:
Good oral hygiene is essential to prevent new stains from forming.
Use a Whitening Toothpaste:
A whitening toothpaste can help maintain the results by removing surface stains.
Avoid Staining Foods and Drinks:
Limit your consumption of coffee, tea, red wine, and other staining agents.
Regular Dental Checkups:
Visit your dentist regularly for cleanings and checkups to keep your teeth healthy and bright.
Touch-Up Treatments:
Depending on the whitening method used, you may need occasional touch-up treatments to maintain the results.
Conclusion
Professional teeth whitening is a safe and effective way to achieve a brighter, more confident smile. Whether you choose in-office whitening, take-home kits, laser whitening, or other cosmetic options like veneers and bonding, dental professionals have the tools and expertise to help you achieve your desired results. By understanding the different methods available and taking proper care of your teeth, you can enjoy a whiter smile for years to come.
Remember, it’s always best to consult with your dentist before starting any whitening treatment to ensure it’s the right choice for your dental health. With the right approach, you can achieve the bright, white smile you’ve always wanted.
