Should I Brush My Teeth Before Using Whitening Strips?

Teeth whitening has become very popular. Many people want a bright, white smile. Teeth Whitening strips are an easy and effective way to achieve this. But there is often confusion about the correct use of these strips. One common question is: should you brush your teeth before using whitening strips? In this article, we will explore the answer to this question and provide some helpful tips for using whitening strips.

What Are Whitening Strips?

Whitening strips are thin, flexible pieces of plastic coated with a whitening gel. The gel usually contains hydrogen peroxide or carbamide peroxide. These chemicals help to remove stains from the surface of your teeth. You apply the strips to your teeth and leave them on for a specified amount of time. The result is a whiter, brighter smile.

Does Teeth Whitening Damage Enamel?

Why Brushing Matters

Brushing your teeth is an essential part of oral hygiene. It helps to remove plaque, food particles, and bacteria from your teeth and gums. Brushing also prevents tooth decay and gum disease. When using whitening strips, it is crucial to start with clean teeth. This ensures the whitening gel can work effectively.

Brushing Before Whitening Strips: The Pros

There are several benefits to brushing your teeth before using whitening strips:

  1. Better Contact: Clean teeth allow the whitening gel to make better contact with the tooth surface. Plaque and debris can block the gel, reducing its effectiveness.
  2. Even Whitening: Brushing removes surface stains and food particles. This helps to ensure the whitening strips work evenly across all teeth.
  3. Fresh Breath: Brushing your teeth before using whitening strips helps to keep your breath fresh during the treatment.

What Not to Eat After Teeth Whitening?

Brushing Before Whitening Strips: The Cons

While there are many benefits to brushing before using whitening strips, there are also some potential drawbacks:

  1. Tooth Sensitivity: Brushing can cause slight abrasions on the enamel. If you use whitening strips after brushing, the gel may cause tooth pain.
  2. Gum Irritation: Brushing too hard can irritate your gums. Applying whitening strips to irritated gums can cause discomfort.

Tips for Using Whitening Strips

To get the best results from your whitening strips, follow these tips:

  1. Read the Instructions: Always read the instructions that come with your whitening strips. Different brands may have different recommendations.
  2. Wait After Brushing: If you choose to brush your teeth before using whitening strips, wait at least 30 minutes before applying the strips. This allows your teeth and gums to settle and reduces the risk of sensitivity.
  3. Dry Your Teeth: Before applying the strips, gently dry your teeth with a clean cloth or tissue. This helps the strips adhere better.
  4. Avoid Eating or Drinking: Do not eat or drink anything, especially staining foods or beverages, immediately after using whitening strips. This helps to maintain the whitening effect.
  5. Follow the Recommended Time: Do not leave the strips on for longer than recommended. Overuse can cause tooth sensitivity and gum irritation.

How Much Does Teeth Whitening Cost?

Alternative Approaches

If you are concerned about brushing before using whitening strips, consider these other ways:

  1. Rinse with Mouthwash: Instead of brushing, rinse your mouth with an alcohol-free mouthwash. This helps to clean your teeth without causing abrasions.
  2. Brush Earlier: Brush your teeth an hour or more before using the whitening strips. This gives your teeth time to recover and reduces the risk of sensitivity.


In conclusion, brushing your teeth before using whitening strips can have several benefits. It helps to ensure better contact, even whitening, and fresh breath. However, it is important to be mindful of drawbacks. These include tooth sensitivity and gum irritation. By following the tips provided and reading the instructions on your whitening strips, you can achieve a bright, white smile safely and effectively.
