Step 1: Preparation

Before diving into teeth whitening, proper preparation is crucial to ensure you achieve the best results with minimal risk to your dental health. Here’s how to get your teeth ready for whitening strips.


Start by cleaning your teeth to remove any food particles and plaque. This step is vital because it ensures that the whitening gel on the strips can contact your teeth directly, without any barriers. However, remember not to brush immediately before applying the strips. Brushing too close to application can irritate your gums. Aim to brush about 30 minutes before you plan to apply the strips, giving your saliva enough time to naturally cleanse any excess fluoride from your teeth.

Dry Teeth

Next, make sure your teeth are dry. This might sound minor, but it’s a game-changer. Drying your teeth helps the strips adhere better and stay in place. You can use a clean cloth or a piece of gauze to gently pat your teeth dry. Avoid touching your gums with the cloth to prevent irritation.

Avoid Fluoride

When preparing for whitening, it’s best to avoid fluoride toothpaste right before you apply the strips. Fluoride can create a barrier that reduces the effectiveness of the whitening agent on the strips. If you’ve brushed your teeth earlier (as suggested), just rinse your mouth with water to ensure no fluoride residue is left.

By following these simple preparation steps, you’re setting yourself up for a successful and safe teeth whitening experience. The key is in the details. Proper preparation can significantly enhance the effectiveness of how to use teeth whitening strips and lead to a brighter smile.

Step 2: Application

Now that you’ve prepared your teeth, it’s time to move on to the application of the whitening strips. This step is crucial for ensuring that the strips perform effectively, giving you that bright smile you’re aiming for. Let’s break it down:


First things first, you need to remove the whitening strips from their packaging. Each strip is typically backed with a plastic liner that protects the gel side which is the active side meant to face your teeth. Carefully peel off this liner. The strips are delicate, so handle them gently to avoid tearing.

Align with Gum Line

Positioning the strip correctly is key to avoiding irritation and ensuring that all your visible teeth get evenly whitened. Align the strip with your gum line, not covering the gums. If the strip touches the gums, it can cause irritation due to the bleaching agent. Make sure it’s straight and centered.


Once the strip is in place, gently press it onto your teeth. Smooth out any bubbles or wrinkles with your fingers or a dry toothbrush to make sure the gel makes good contact with the surface of your teeth. This helps in effective whitening.

Fold Behind Teeth

For the excess part of the strip that extends beyond your teeth, fold it behind for a snug fit. This ensures that even the edges of your teeth are covered, which contributes to a uniform whitening effect.

Using Crest 3DWhitestrips, as we are discussing here, follow these steps carefully. These strips are designed to adhere well and mold to the shape of your teeth, maximizing the contact of the whitening agent with your enamel.

By following these application steps diligently, you’re well on your way to achieving a brighter smile. The correct application not only improves efficacy but also minimizes the risk of gum sensitivity and irritation. Let’s move on to how long you should keep the strips on and how often to use them for optimal results.

Step 3: Timing and Consistency

When using teeth whitening strips, it’s crucial to pay attention to how long and how often you use them. Getting this right means you’ll see the best results without harming your teeth. Let’s break down the essentials:

Daily Application

Most teeth whitening strips, including Crest Whitestrips, are designed for daily use. This consistent application is key to breaking down stains gradually and achieving a noticeably whiter smile. It’s important to follow the specific instructions provided with your product, as the frequency can vary.


The amount of time you should leave the strips on your teeth varies by product. Typically, this can range from 5 to 60 minutes depending on the strength of the whitening agent. For example, some Crest Whitestrips only need to be worn for 30 minutes to achieve full effect. Always check the package for the exact timing and follow it closely to avoid damaging your enamel.

Crest Whitestrips Instructions

Each package of Crest Whitestrips comes with detailed instructions that should be followed meticulously. These instructions will tell you:
– How long to leave the strips on.
– How often to apply them.
– Any additional steps (like using a light, if included).

Following these instructions is vital for safe and effective whitening.

Avoid Overuse

While it might be tempting to use whitening strips more often than recommended to get quicker results, this can lead to tooth sensitivity and gum irritation. Overuse can also strip away enamel, leading to long-term dental issues. Stick to the recommended frequency and duration to safely achieve a brighter smile.

By keeping these guidelines in mind, you ensure not only the effectiveness of the whitening process but also the health of your teeth. Next, we’ll look at how to care for your teeth post-whitening to maintain those gleaming results.

Step 4: Aftercare

After you’ve used your whitening strips, taking the right steps can help maintain your new bright smile and ensure your teeth stay healthy. Let’s dive into the essentials of aftercare.

Avoid Dark Foods

Right after whitening, your teeth are more susceptible to staining. For the next 24 to 48 hours, it’s wise to avoid dark-colored foods and beverages such as coffee, red wine, dark sodas, and berries. These can stain your teeth and undo all your hard work!


After removing the strips, rinse your mouth thoroughly with water. This helps to remove any remaining whitening gel, which can continue to react if left on your teeth and gums. A clean rinse ensures that no residue is left to cause irritation or sensitivity.

Whitening Toothpaste

Incorporating a whitening toothpaste into your routine can help maintain the results. Use a toothpaste that’s designed to enhance whiteness, such as those containing mild abrasives that gently polish the teeth or chemicals that help break down or dissolve stains. Use this 2-3 times a week instead of your regular toothpaste to keep your teeth looking bright.


Flossing isn’t just for general dental health; it also plays a key role in maintaining your whitening results. By flossing at least once a day, you remove plaque and food particles that can lead to staining between the teeth where strips might not reach.

Oral-B Pulsar 3D White Advanced Vivid Toothbrush

For daily maintenance, consider using the Oral-B Pulsar 3D White Advanced Vivid toothbrush. This toothbrush is designed not only to clean but also to polish your teeth, enhancing their whiteness. Its vibrating bristles help break up plaque and surface stains from all angles.

By following these aftercare steps, you can extend the longevity of your whitening results and enjoy a brighter smile for longer. Next, we’ll explore how to choose the right whitening product to suit your needs and preferences.

Step 5: Choosing the Right Product

When it comes to how to use teeth whitening strips, selecting the right product is crucial for achieving the best results without compromising your dental health. Here’s a breakdown of factors to consider:

Crest 3DWhitestrips Options

Crest offers a variety of 3DWhitestrips to cater to different whitening needs. Whether you’re looking for a quick touch-up or intensive whitening, there’s a product for you. For instance, if you need a rapid whitening solution for an upcoming event, the Crest 3DWhitestrips 1 Hour Express might be ideal. On the other hand, for a more gradual whitening, the Crest 3DWhitestrips Glamorous White could be the better choice.

ADA Approval

The American Dental Association (ADA) Seal of Acceptance is an important indicator of a product’s safety and effectiveness. Products that carry this seal, like some of the Crest 3DWhitestrips, have been rigorously tested and approved by the ADA, ensuring they are safe to use and effective in whitening teeth when used as directed.

Customer Reviews

Reading through customer reviews can provide real-world insights into the effectiveness and ease of use of different whitening strips. Many users share their experiences with sensitivity, the whitening effect, and the overall usability of the product. This feedback can be invaluable in helping you choose the right product.


If you have sensitive teeth, opting for a gentler option is key to comfortable whitening. The Crest 3D White Whitestrips Sensitive + LED Light is specifically designed for people with sensitive teeth. It uses the same enamel-safe ingredients dentists use but in a lower concentration.

Crest 3D White Whitestrips Sensitive + LED Light

This particular option is excellent for those who experience sensitivity but still desire effective whitening. It includes a LED light that helps to accelerate the whitening process, allowing for noticeable results in just 30 minutes a day. This product provides a balance between gentleness and effectiveness, making it a popular choice for those with sensitivity concerns.

By considering these factors—product options, ADA approval, customer reviews, and your sensitivity needs—you can make an informed decision on which Crest 3DWhitestrips will best meet your teeth whitening goals. The right product not only improves the appearance of your smile but also ensures a safe and comfortable whitening experience.

Frequently Asked Questions about Teeth Whitening Strips

Do you brush your teeth before using whitening strips?

Yes, you should brush your teeth before applying whitening strips. This helps to remove any plaque or debris on your teeth, ensuring that the whitening gel in the strips can effectively contact the tooth surface.
