What Are Professional Teeth Whitening Trays?

Professional teeth whitening trays are custom-made dental devices designed to whiten and brighten the color of teeth. They are commonly used in dental clinics or under the supervision of a dentist, offering a more effective and personalized approach to teeth whitening compared to over-the-counter whitening products.

These trays are typically made from a flexible plastic material that molds to the shape of your teeth, ensuring a comfortable fit and even distribution of the whitening agent. The process of obtaining professional teeth whitening trays involves an initial consultation with a dentist or dental professional who will take impressions of your teeth. These images are then sent to a dental laboratory where the trays are fabricated to precisely fit your mouth.

One of the significant advantages of professional teeth whitening trays is their ability to reach deep stains and discoloration that are difficult to address with surface-level whitening methods. Furthermore, professional teeth whitening trays allow for a more controlled and customized whitening experience. Since the trays are tailored to your mouth’s unique shape, they provide consistent coverage, ensuring that every tooth receives an equal amount of whitening gel. This personalized approach helps avoid uneven results often associated with generic over-the-counter whitening products.

How Do They Work?

The active ingredient in most teeth whitening gels is hydrogen peroxide or carbamide peroxide. These chemicals penetrate the enamel of the teeth and break down the stains, leaving the tooth looking whiter and brighter. The trays hold the gel in place so that it can do its job effectively.

Teeth whitening gels typically contain either hydrogen peroxide or carbamide peroxide as their active ingredient. These chemicals are responsible for the whitening effect on teeth. When applied to the teeth, they are able to penetrate the enamel, which is the outer protective layer of the teeth.

Once the hydrogen peroxide or carbamide peroxide reaches the dentin, the layer beneath the enamel, it starts to break down the stains that have accumulated on the teeth. These stains can be caused by various factors such as consumption of colored foods and beverages, smoking, or poor oral hygiene.

The process of breaking down the stains involves a chemical reaction, where the peroxide molecules release oxygen ions. These oxygen ions are highly reactive and are able to react with the pigment molecules in the stains, causing them to break apart. As a result, the stains become less concentrated, and the overall appearance of the tooth becomes whiter and brighter.

To ensure that the teeth whitening gel is applied evenly and stays in contact with the teeth for an extended period, trays are commonly used. These trays are typically made of flexible material that conforms to the shape of the teeth. The gel is applied to the tray, and then the tray is placed over the teeth, holding the gel in place. This allows for optimal contact between the gel and the teeth, ensuring that the whitening process is effective.

Pros of Using Whitening Trays

Custom Fit

Since the trays are custom-made for your teeth, they offer a more precise fit than over-the-counter products. This ensures that the gel is evenly distributed and reduces the risk of gum irritation.

Stronger Formula

Professional-grade whitening gels contain a higher concentration of bleaching agents than over-the-counter products, which means they can achieve better results in a shorter amount of time.

Long-Lasting Results

With proper care, the results of professional teeth whitening can last for several years.

Cons of Using Whitening Trays

While there are many benefits to using professional teeth whitening trays, there are also some potential drawbacks to consider, including:


Professional teeth whitening can be expensive, with prices ranging from a few hundred to several thousand dollars depending on the type of treatment and the dentist you choose.


Teeth whitening can cause temporary sensitivity or discomfort, especially if the gel comes into contact with the gums. This is more likely to occur if the trays are not properly fitted or if they are left on for too long.

Time Commitment

Professional teeth whitening trays require a time commitment, as they need to be worn for several hours each day over a period of several weeks. This may not be practical for everyone’s lifestyle.

Step-by-Step Guide to Using Whitening Trays

If you’ve decided to try professional teeth whitening trays, here’s how to use them:

  • Schedule an appointment with your dentist or dental hygienist to have the trays made.
  • Follow the instructions provided by your dentist for using the trays and the whitening gel. This may involve wearing the trays for a certain amount of time each day, usually for several weeks.
  • Be sure to brush and floss before using the trays to remove any food particles or debris that could interfere with the whitening process.
  • If you experience sensitivity or discomfort, take a break from using the trays or talk to your dentist about adjusting the treatment plan.

Comparing Different Types of Whitening Trays

Custom-Fit Trays

These trays are made specifically for your teeth and offer the most precise fit. They are usually more expensive than other options but also offer the best results.

Boil-and-Bite Trays

Boil-and-bite trays are heated in water and then molded to your teeth for a semi-custom fit. While they are less expensive than custom-fit trays, they may not be as effective or comfortable to wear.

One-Size-Fits-All Trays

One-size-fits-all trays are pre-made and designed to fit most people’s teeth. While they are the cheapest option, they may not be as effective or comfortable as custom-fit trays.

Tips for Getting the Best Results

Use a High-Quality Whitening Gel

Be sure to use a high-quality whitening gel that contains a sufficient amount of bleaching agent. Talk to your dentist about which products they recommend.

Follow the Instructions Carefully

Follow the instructions provided by your dentist carefully, including how long to wear the trays each day and how often to use them.

Avoid Staining Foods and Drinks

Avoid foods and drinks that can stain your teeth, such as coffee, tea, red wine, and tomato sauce, while using the trays.

Practice Good Oral Hygiene

Brush and floss regularly to maintain good oral hygiene and prolong the results of your teeth whitening treatment.
