Whiten your teeth for a dollar

Yes, you heard that right, I whiten my teeth for a under a dollar!  I have been meaning to write about this forever and just forgot so here you go.


I was talking to one of my girlfriends way back when and her dad is a dentist.  She confirmed everything I “thought” I knew.  She said Kristin, your dentist isn’t going to tell you to go out and buy yourself a bottle of peroxide or they would be out of business!


About a year ago I stopped using the $30 kits and started using a $1.00 bottle of peroxide and it worked just as good if not better.  (hence why I don’t have a before and after picture as I have been whitening my teeth forever)

Next time you are at the store check out the active ingredients in the whitening kits and toothpastes, promise hydrogen peroxide will be listed.  Those whitening products that you pay $30 for are just glorified Hydrogen Peroxide in a pretty little package.

So here are the steps I follow


I Brush my teeth with toothpaste. However at my last dentist app’t he recommends just brushing with listerene mouth wash and there was no need for toothpaste.  I tried it but it just didn’t feel right, I think I need something abrasive to make my teeth feel “clean”.


Rinse with 3% hydrogen peroxide for 30-60 seconds. (anything higher must be diluted with 50% water) When the hydrogen peroxide comes in contact with your mouth, a chemical reaction will take place and it will begin to foam, don’t worry it’s normal.


Spit out the rinse, do not swallow!

~That’s it, promise~



I have heard if you have never used any type of whitening agent on your teeth the Hydrogen peroxide treatment will take awhile, at least 6 months.  However if you have pretty white teeth to begin with or have used the whitening agents in the past this is a fabulous way to keep up the look for the fraction of the cost.



So what do think, are you going to try it? Have you been doing this already? I wan’t to hear your thoughts!

    1. The kits actually made my teeth sensitive, the peroxide does not. I would say if your teeth get sensitive use it every other day 🙂

    1. I do it a few times a week. If your teeth are yellow I would start with a kit then move over to the peroxide after you get them to the color you want. 🙂

  1. It does work does’t it!! I worked for a DDS for several years and she shared this with me. I couldn’t believe it. Great post Kristin! Enjoy your weekend.

  2. Great tips, Kristin – thanks! How much does 3% equate to – roughly a capful perhaps? Arm & Hammer baking soda will achieve very good results as well, and much like the HP, will take a while before you see the difference. Definitely worth it and achievable. heather x

  3. I am so glad you are writing about this. I tried the peroxide last year but it didn’t seem to do anything so I gave up. Just this week I bought the Crest whitening strips. It did make a noticable difference but I am going to use another set next week. I didn’t realize that it would take up to six months so for the peroxide to work so after I get them white I will give the peroxide another try to keep them white.
    Just fyi, be sure to rise your sink, the peroxide did cause the ORB finish on my drain cover in sink to become cloudy.

    1. Thanks Debbie for the info. The peroxide I buy does have directions for using as a oral rinse, it should never be swallowed. One should only do this if they are comfortable with it. Same goes with the kits, they should never swallow the gel 🙂

  4. I can’t tell you how much time these teeth have spent in Crest Whitestrips or trays over the years (I love my coffee and red wine!!) THANK YOU for this tip – I am going off to try it right now! I love when you write about beauty stuff. I will do anything you tell me to, my gorgeous friend 🙂
