Do I wash my teeth before or after whitening strips?

Whitening strips have become increasingly popular over the years as a convenient and affordable way to achieve a brighter smile. However, many people are unsure about the proper steps to take before and after using these strips. One common question that arises is whether to wash your teeth before or after applying whitening strips. In this article, we will explore this topic in detail and provide some valuable insights to ensure you get the best results from your whitening experience.

Understanding the Benefits of Whitening Strips

Before diving into the main topic, let's briefly understand why whitening strips have gained such immense popularity. These strips are essentially thin, flexible pieces of plastic coated with a whitening gel that contains hydrogen peroxide, the active ingredient responsible for lightening your teeth. When applied regularly, these strips can effectively remove stains and discoloration caused by coffee, tea, tobacco, and other factors, leaving you with a brighter and more confident smile.

The Importance of Oral Hygiene

Maintaining proper oral hygiene is crucial for overall dental health. Before incorporating any new product into your dental routine, it's important to remember the basics. Regular brushing, flossing, and rinsing with mouthwash should never be overlooked. These fundamental habits lay the foundation for any dental treatment, including teeth whitening.

Preparing Your Teeth for Whitening Strips

Before using whitening strips, it is important to prepare your teeth properly. This involves a few essential steps to ensure optimal results and minimize any potential sensitivity:

1. Brush your teeth: It is recommended to brush your teeth thoroughly before applying the whitening strips. This helps remove any food particles or plaque that could interfere with the whitening process. Use a soft-bristle toothbrush and fluoride toothpaste to gently clean all surfaces of your teeth.

2. Flossing: Flossing plays a crucial role in oral hygiene, and it becomes even more important before whitening your teeth. By removing any trapped food or plaque between your teeth, you create a clean canvas for the whitening gel to work its magic. Take your time and floss properly, paying attention to each tooth.

3. Rinse your mouth: After brushing and flossing, rinse your mouth thoroughly with water. This helps remove any remaining toothpaste or debris and ensures a clean and fresh environment for the whitening strips. Some dentists also encourage using an alcohol-free mouthwash to further cleanse your mouth.

Applying Whitening Strips

Now that your teeth are properly prepared, it's time to apply the whitening strips. Follow these steps for successful application:

1. Dry your teeth: Before applying the strips, make sure your teeth are completely dry. Excess moisture can impact the adherence and effectiveness of the strips. You can use a tissue or a clean, dry cloth to gently pat your teeth dry.

2. Apply the strips: Take out the whitening strips from the packaging and carefully place them on your upper and lower teeth. Make sure the gel-coated side is in contact with the surface of your teeth. Align the strips with your gum line and press down gently to ensure proper adhesion.

3. Leave on for the recommended duration: Each brand of whitening strips will have specific instructions regarding the recommended usage time. It is crucial to follow these instructions carefully to avoid any potential harm to your teeth and gums. Most whitening strips require 30 minutes to an hour for optimal results.

Dental Care After Whitening Strips

After whitening your teeth, it is important to continue practicing good oral hygiene habits and take certain precautions to maintain the results:

1. Brush your teeth: After removing the whitening strips, brush your teeth gently with water to remove any residual gel. However, avoid using toothpaste immediately after removing the strips, as some brands recommend waiting for a specific time period before brushing with toothpaste.

2. Rinse your mouth: Use a mouthwash or simply rinse your mouth with water to remove any leftover gel and freshen your breath. This step helps neutralize any remaining whitening agents in your mouth.

3. Avoid staining substances: In the hours following whitening, it is advisable to avoid consuming staining substances like coffee, tea, red wine, or tobacco. These can interfere with the whitening process and potentially re-stain your teeth.

4. Maintain regular oral care routine: Continue brushing your teeth twice a day, flossing, and rinsing with mouthwash to maintain good oral hygiene. This will help prolong the effects of the whitening treatment and keep your teeth healthy and clean.


Whitening strips can be a highly effective way to achieve a brighter smile and boost your confidence. By properly preparing your teeth before applying the strips and following a simple oral care routine afterward, you can maximize the results and maintain a beautiful, radiant smile. Remember, consulting with a dentist is always recommended before starting any whitening treatment to ensure it is suitable for your dental condition.
