May 15, 2023

Did you try whitening your teeth at home using strips? It’s a great way to brighten your smile quickly when you are going out in a hurry or need to enhance the appearance of your teeth. Although whitening strips are not as effective as professional teeth whitening, they do just fine. But many people wonder, do you brush your teeth after whitening strips or not?

In this blog, we will explain all that you should know about teeth whitening strips and brushing. Learn more by reading the article!

Can I Brush My Teeth After Using Whitening Strips?

To answer, you can brush your teeth right after using whitening strips. If you do brush your teeth, manufacturers recommend using a gentle approach. However, sometimes, teeth sensitivity after whitening takes place. Therefore, wait for the sensitivity to go away before you brush your teeth. This might take an hour or so — it is better to scrub your teeth when they are not sensitive due to whitening.

Brushing Before Teeth Whitening Strips

If you want to brush your teeth right before you apply the whitening strips, though, it isn’t suitable. In fact, you should wait at least 30 minutes after brushing to use the product. This is because if you apply the strips immediately after brushing, it can irritate your gums. Moreover, brushing results in a smooth teeth surface — which is not ideal for the strips to stick properly.

You can, however, brush and floss 30 minutes prior to using the strips. This way, the efficacy of the procedure increases since the plaque no longer stands between your teeth and the strips.

Some Common Side-Effects

Did you know using whitening strips might have some side effects? Temporary gum inflammation and teeth sensitivity are two primary effects that take place when you use whitening strips. However, the higher the peroxide content, the more these effects would be. But these issues would be short-lived; they will not have lasting discomfort.

You can try the following to alleviate the sensitivity and inflammation:

  • Brushing teeth with the help of a toothbrush that has soft-bristles
  • Clean your teeth with toothpaste designed for sensitive teeth
  • Decrease the number of acidic foods and beverages, alcohol, tobacco, and strong mouthwashes you consume
  • Saltwater rinses
  • Use cold or warm compresses against your gums
  • Stay hydrated to increase salivary flow

If your symptoms keep getting worse, talk to a dentist.

Tips for Safely Using Teeth Whitening Strips

Here are some convenient ways you can improve the experience and avoid potential dental issues:

  • Follow the instructions and remain consistent.
  • Be careful when applying the strips.
  • Stay on top of your oral hygiene.
  • Be mindful not to overuse the strips, especially following the recommended time.
  • Avoid applying them to your gums.
  • Limit foods and drinks that are dark in color.
  • Do not smoke cigarettes.


In conclusion, you can brush your teeth right after using whitening strips. However, it is better to wait 30 minutes if you have brushed your teeth before applying the strips.
