There’s An Easy And Affordable Way To Whiten Your Smile

Whiten your teeth at home with just two household ingredients.

Save A Fortune With Homemade Teeth Whitening

It’s estimated that Americans spend a staggering $1.4 billion on over-the-counter teeth whitening products every year! So if you’ve ever found yourself wishing you had whiter teeth, you can at least take solace in the fact that you’re far from the only one.

Then again, maybe that figure isn’t all that surprising — a box of 20 sets of whitening strips can set you back over $40, after all! But the good news is that you don’t need to spend that kind of money in order to whiten your teeth.

In this post, I’ll tell you about a simple way you can whiten your smile at home for pennies. And what’s more, there’s a good chance you already have everything you’ll need in your cupboards at home!

Baking soda helps gently scrub your teeth to get them white.

DIY Teeth Whitening With Baking Soda And Hydrogen Peroxide

This treatment contains two inexpensive ingredients that work together to scrub away stains and leave teeth whiter and brighter. First, there’s good ol’ baking soda, which helps to gently erase surface stains on teeth and break down plaque buildup. (You can learn about all the other wonderful things baking soda can do at the link below!)

Hydrogen peroxide helps whiten your teeth and kill bacteria to keep your mouth fresh and clean.

The second ingredient in this treatment is hydrogen peroxide, which helps fight bacterial buildup in all the nooks and crannies of your teeth and gums. Hydrogen peroxide has been used for oral health for decades, and is proven in clinical tests to whiten teeth stains and protect against gingivitis. (For more uses for hydrogen peroxide, check out my e-book Hydrogen Peroxide Magic! or the post at the link below.)

In addition to using baking soda and hydrogen peroxide for teeth whitening, I like to add a bit of lemon essential oil as well. This optional ingredient has antimicrobial properties and can help whiten teeth without harming the enamel. (Lemon oil is extracted from the peel and pith, so it doesn’t contain any enamel-eroding citric acid.)

Now that you know what goes into it, here’s how to make this homemade teeth whitening treatment.

How To Make A Peroxide & Baking Soda Teeth Whitening Paste

Hydrogen peroxide, baking soda, and lemon essential oil are the three powerhouse ingredients in my natural teeth whitening formula.


To make the teeth whitening formula, just mix the three ingredients in a small bowl.


Add the baking soda, peroxide, and essential oil (if using) to a small bowl and mix well with a small whisk or a fork.

Scoop a small amount onto your toothbrush, brush your teeth as usual, then rinse your mouth thoroughly after with clean water.

Use this homemade whitener paste 1-2 times per week (in addition to brushing with toothpaste twice daily) to whiten teeth, freshen breath, and promote good oral health.

Brush your teeth with this teeth whitening formula two or three times a week.

Not only does this simple mixture help brighten my smile, but it makes my teeth feel extra clean — even cleaner than they do after brushing with normal toothpaste.

Oil pulling with coconut oil can also help with teeth whitening.

Using Coconut Oil To Whiten Teeth

Along with many other benefits, the lauric acid in coconut oil can help kill bacteria in your mouth, including surface bacteria that contributes to yellowing. To use coconut oil for teeth whitening, try oil pulling each evening to clear out bacteria that’s built up on your teeth throughout the day.

Don't use apple cider vinegar to whiten your teeth -- the acid in vinegar can damage your enamel.

2 Things You Shouldn’t Use To Whiten Your Teeth

1. Apple Cider Vinegar

Apple cider vinegar can help kill bacteria, but there are dangers to using it as a DIY teeth whitening solution. The acetic acid in ACV can erode tooth enamel over time, leaving your teeth more sensitive and prone to cavities, so you’re better off leaving that bottle on the shelf!

2. Strawberry Paste (Or Any Fruit Paste)

One popular home remedy for teeth whitening involves using strawberries to make a natural toothpaste, but it doesn’t actually work. Your teeth may appear whiter at first due to the exfoliating effect of strawberries, but it doesn’t break down the actual stains.

  • Nice article! thanks for sharing your information. If you want whiter teeth, but also want to avoid the chemicals then Try Oil Pulling, Oil pulling is a traditional Indian folk remedy meant to improve oral hygiene and remove toxins from the body. A few studies have shown that daily oil pulling effectively reduces bacteria in the mouth, along with plaque and gingivitis.

  • Oral surgeons are out to…………make a lot of money. Why do you have an oral surgeon? Many tooth issues can be overcome with an excellent diet. Stay away from sugar, it’s worse than peroxide!!! Borrow the book from the library called, Cure Tooth Decay.

  • Thanks a lot for the info. I will apply these techniques to whiten my teeth. But also it is good to see a dentist if your white is too yellow or you have any other dental problem.

  • I have a question about measuring drops. My hydrogen peroxide comes with a lid that squirts the peroxide tho I try to make drops. How do I get drops measured?

  • This is ok on an occasional basis but do not use this everyday. Hydrogen peroxide will kill gum tissue if used daily over a period of time. Also, baking soda (basically salt) should be used sparingly by anyone who has high blood pressure.

  • Okay, I’m confused. You say this is for a one time use, and that the peroxide becomes ineffective, but you also said it could be stored in a cool dark place for a couple of weeks. One tablespoon is way more than you would need for one treatment, even a teaspoon would be a lot, and if it is only for one use, why would you make that much at a time? Makes more sense to me to use abut a half a teaspoon or so in a cup with a little peroxide and make it fresh each time you use it.

    • It’s best to make a small amount. If you made a ton and don’t know what to do with it, then you might as well keep using it for a couple weeks. It will lose some effectiveness, but will still do the trick! Ideally, you should make the smallest amount at a time. :-)

  • There is food grade peroxide if it worries you. It’s usually at 35% and very caustic. Once you dilute it 1:11 (1part peroxide to 11 parts distilled water) it’s 3% like off the store shelves but without the additives.

  • I think it would be OK to make a larger quantity in small wide-mouth jar kept away from light or in a dark (blue or amber) jar. I made the recipe x4 and added 2 teaspoons Xylitol (sweetener), which is an ingredient I use in my regular toothpaste formula and is supposed to be good for your teeth.

  • Peroxide loses it’s power when exposed to oxygen and light, which is why it’s sold in a brown container with a screw-on top. So, the answer is to make it one batch at a time.

  • I’d like to know if this would be safe for dentures…. I’ve used the plain baking soda for years & have never noticed any whitening of my teeth, altho it works wonders on your stained coffee cups etc.

  • I keep a cute small jar of baking soda in my sink cabinet and about every other night I dip a moistened toothbrush in it, picking up maybe 1/4 tsp of soda to brush with. (This is instead of using toothpaste.) When I have a dental appt coming up I increase use to daily for a few days, keeping my teeth pretty clean so the hygenist doesnt have much to do. If I notice staining, I occasionally do moisten my brush with peroxide first. Although it whitens well, it tastes nasty, so the peppermint idea is a great one. Sometimes I also wipe a teeny sprinkle of the baking soda around any soap scum in my sink with with a kleenix or washcloth while I brush, and my teeth and sink are clean and shiny!

    • I just moisten my toothbrush with some hydrogen peroxide and then dip it into some baking soda and brush! I have both in my bathroom cabinet and use whenever I feel I need a good whitening and cleaning.

  • I used to this years ago. Is that amount of baking soda correct. 1T seems like too much. I would usually just eyeball it and use a capful of peroxide. My mouth area can be very sensitive that’s why I can’t use a lot of the popular whitening brands. My teeth are also a little yellowish , naturally. My mom and her sister both have the same teeth.

    • My teeth are also sensitive to certain things and I also use dental products to keep my gums from bleeding. I’m hoping this treatment wouldn’t aggravate it.

      • Hi Christymn, I tried this recipe yesterday after reading the blog. Unfortunately for me, this recipe caused my mouth and teeth to hurt.

    • Peroxide loses it’s power when exposed to oxygen and light, which is why it’s sold in a brown container with a screw-on top. So, the answer is to make it one batch at a time.

    • This is just a one-time use treatment. :-) Hydrogen peroxide has to be stored in a dark bottle – it breaks down quickly once you’ve poured it out of its bottle.
