I am not ashamed to admit that I am a fan of most teeth staining agents dentists warn you about. I am an early riser in the morning, and for me this means a big cup of coffee. Okay, a lot of big cups of coffee. After a long, busy day, I savor my glass of red wine with dinner. I brush my teeth twice a day as recommended by my dentist, but brushing and flossing alone just wasn’t battling the stains I would acquire behind my teeth and in between the cracks.

For the longest time I was a huge fan of Crest White Strips Advanced, when I could afford them, that is! They whitened my teeth and kept them white for long periods of time. But recently, I started looking for cheaper solutions.

I thought maybe I could get a general idea of the products used in Crest White Strips and make my own whitening concoction! Oddly enough, one of the main ingredients in Crest White Strips is hydrogen peroxide. This triggered a research journey! I spent lots of time Googling hydrogen peroxide and whether or not it’s safe to put in your mouth. If it’s safe in Crest White Strips, then I figured a quick swish couldn’t hurt.

Before I gave it a shot, I sought out professional advice from my dentist. She advised me that it wouldn’t hurt, but like all over-the-counter mouthwashes, it is not safe to swallow. She also said that making my own toothpaste using hydrogen peroxide and baking soda would be great for whitening too!

So that’s what I did, and it’s so easy to make. I use a Tupperware bowl and combine two parts baking soda to one part hydrogen peroxide and mix until I get a toothpaste consistency. You can store it for a few days, but I don’t usually keep it past five! As with all products used in your mouth, you should ask your dentist first if it’s safe for you.

Swishing hydrogen peroxide once daily and using my own homemade toothpaste has saved me hundreds of dollars per year and has given me a bright white smile. The best part of all: people often ask me, “Where do you get your zoom whitening done?”

    I have found that using a few drops of GSE on my toothpaste on my toothbrush really gives my teeth that super clean feeling and look. I can still use my regular toothpaste with fluoride but get the added cleaning each time I brush. The GSE I get at amazon and a 4 oz bottle lasts a long long time! (years)

    My 91yr old grandmother has done this her whole life, she uses a little glass dish and mixes it every night. She uses regular toothpaste in the mornings. Everyone is always amazed that she has all her teeth and they look fabulous!

    I saw on pinterest that someone dips q-tip in hydrogen peroxide and paints their teeth with it. Wait a half hour, then gargle with water.

  5. My dentist also told me that this helps to keep your gums from becoming inflamed especially during a sinus infection!

    I must say, as a dental professional, that swishing with peroxide can be irritating and harmful to the oral tissues. Sure, the teeth can handle it no problem, but it’t too rough on the tissues inside the mouth.  Whitestrips are ok because the bleaching agent stays localized to the teeth.  Have you ever seen what happens to the gums, though, if you get the whitest gel on them?…ouchy.  I think the toothpaste idea is a lot safer sounding.  Also, don’t forget a fluoride!

      Laryssa555, I too, am a Dental Professional, a Dental Hygienist. I was also worried about the fluoride factor. Ladies, you can get fluoride by ACT Rinse, or, fluoride is in the pharmacy (under the counter, just ask) I think a tube runs about $10. It lasts forever, and a small amount can be brushed on after you’ve done your plaque removal (brushing and flossing). Don’t laugh, but when I was “just a kid” our toothpaste came in a can (Pepsodent) and it was basically baking soda. Then we got Ipana, in a tube….. improvement !!!!  hahaha  Good Luck <3

        Wow you are dating yourself and me! LOL! We too used the can of pepsodent(you’ll wonder where the yellow went when you brush your teeth with pepsodent!” AND Ipana! “Brusha brusha brusha with the new Ipana toothpaste, brusha brusha brusha  it’s good for your teeth”! Thanks for reminding me of that memory!

          Glad to remind you <3, I was a Dental Hygienist for 46 years and my Grandpa was a Dentist. We've been through a lot of "changes" over the years. Remember when the argument was over waxed or non-waxed floss?….. When we couldn't even get folks to floss !!! That one was really stupid. haha, I loved those Ipana commercials with the little "Bucky Beaver".  War Babies ROCK !!!!

  9. I’ve done this for most of my adult life, mostly because I love how clean my teeth get.  When I use toothpaste, I can feel the dirty on my teeth within a few hours, but not with baking soda & peroxide!  One thing that’s missing here, tho, is fluoride, so make sure you use some toothpaste with that in it a few times a week.

    I’ve done this and added a few drops of peppermint flavoring, peppermint essential oil, or toothpaste for flavor. I also mixed my mouthrinse with 2 parts of peroxide, and rinse before and after each brushing. It really makes a big difference!

    Are you using anything else or just your homemade toothpaste? If not don’t you miss the minty after taste

    What about flavor/taste? I’ve tried swishing hydrogen peroxide and I just can’t get past the taste in my mouth. Do you have any suggestions? Maybe mixing a little toothpaste for that mintly flavor?
