Can I rinse with peroxide to whiten my teeth?

I learned that teeth whitening is mostly a peroxide mixture. Couldn’t I get a faster and similar results by rinsing with peroxide at home? I want to get this done quickly. My dentist is talking about me wearing the peroxide gel for a few weeks. I’m thinking straight peroxide will be better.


Dear Lucy,

You want to get teeth whitening done fast and you can, but it won’t happen with rinsing your teeth with peroxide. You are correct that a teeth whitening gel is made of peroxide. However, it is only effective if it soaks into your teeth.

When your dentist creates a tooth whitening tray for you, he does it so they will have a close custom fit to your natural teeth. With the solution being a gel, it will stay on your teeth better in the tray.

It will need to soak in for a minimum of 15 minutes a day for there to be any whitening effect. I don’t think you’re going to feel comfortable rinsing for 15 minutes a day. Even then, it would take a few weeks.

Getting Your Teeth Whitened Fast

If you really want your teeth whitened fast, look for a dentist who offers Zoom Whitening. This is an in-office procedure that will completely whiten your teeth in just one appointment.

This is a safer option for you than gargling with peroxide every day.

A Smile Makeover

Another option for fast, white teeth is to get a complete smile makeover with porcelain veneers. I would only recommend this if you want to change more than just the color of your teeth.

Porcelain veneers can change the shape, size, and color of your teeth all at the same time. It’s what celebrities use as their go-to for their Hollywood smile.

If all you want is to do whiten your teeth then I would just stick with Zoom. It is much less expensive.
