Should You Brush Your Teeth Before Using Whitening Strips or After?

September 30, 2023

When people say that a smile defines the beauty of your soul, they truly do mean it. After all, your smile is the biggest weapon you have in today’s day and age. It’s one of the reasons why people opt for multiple dental treatments, trying to beautify their smile.

Whether it’s straightening them with the help of braces or brightening them with teeth whitening, cosmetic dentistry has been soaring. Plus, with teeth whitening strips, everything has become all the more easier. The only thing is that sometimes, dealing with DIY dental procedures can be a bit tricky. For instance, should you brush your teeth before using whitening strips or after? In fact, are they even safe for use? To learn more about at-home whitening strips and the best way to use them, keep reading this blog.

Are At-home Whitening Strips Safe to Use?

Teeth whitening strips are known to contain strong bleaching agents such as carbamide peroxide and hydrogen peroxide that help to lift the dullness off your enamel. While this might be a dangerous combination on its own, generally, they are considered to be safe.

If your teeth whitening strips have the seal of approval from the American Dental Association (ADA), then you’re all in the clear. However, to ensure that your whitening strips are effective, make sure to run them by your dentist.

It is also important to keep in mind that the bleaching agents present in the strips can irritate your gums. Thus, when using, make sure the strips do not come into contact with your gums.

Should I Brush My Teeth Before Using Whitening Strips?

Most dentists recommend brushing your teeth at least 30 minutes before starting your at-home teeth whitening procedure. Brushing your teeth in advance actually helps to stabilize the enamel, keeping it from wearing away since it gets rid of plaque and bacteria. Not to mention, it also allows the whitening strips to stick to the teeth better, producing effective results.

However, if you brush your teeth after whitening your teeth, it can have dire effects, causing more harm than good. The reason for this is that the bleaching agents on the strips weaken your enamel. So, when you brush your teeth after, the thin enamel layer might not be able to protect the insides of your teeth. This often gives way to oral hypersensitivity, pain, and irritation.

Plus, depending on your oral care routine, brushing can prove to be abrasive for your teeth if done after, which is why doing so beforehand is much better.

Closing Words

While professional teeth whitening is a far safer option than at-home teeth whitening strips, if you still do manage to do it yourself, make sure to consult with your dentist first. You should also follow the proper steps by brushing your teeth before using the whitening strips for brighter results.
