I used to use those horrid teeth whitening strips. You know the ones I’m talking about.

I don’t know about you but they left me in complete and total pain!

If the wind blew, that was enough pressure to drive me mad. Not to mention the fact that I could never get them to stick.

And that I felt like I shouldn’t really swallow cause, heck, who knows what’s on those things anyways?

To get back to the point (was I ever on it in the first place? Oops!) I’ve been using an all-natural, super easy DIY teeth whitening paste for awhile now and have seen great results!

Did I mention it was easy?

We don’t need any unhealthy, crazy chemicals to keep our teeth white.

Nor do we need to drop major money on expensive teeth whitening products!

We can easily make our own natural teeth whitening paste at home with just a few simple ingredients.

This paste is made with just 3 ingredients, two of which are well-known for their teeth whitening benefits — in fact, many whitening toothpastes, mouth washes, whitening strips, etc. etc. contain one or both of them.

Baking soda

Baking soda teeth whitening pastes are tried-and-true. A number of studies (like this one, this one, and this one) have found that toothpaste with baking soda whitens teeth more effectively than toothpastes without baking soda.

Not only does baking soda gently polish away stains on teeth, but studies have found that it also helps kill unhealthy bacteria and prevent plaque build-up by creating an alkaline environment in your mouth (a very big bonus!).

Hydrogen peroxide

Hydrogen peroxide teeth whitening strips and mouthwashes are also popular and for good reason: peroxide is a natural bleaching agent and helps to improve gum health by keeping unhealthy bacteria under control (source).

Peppermint essential oil

Not only does peppermint essential oil provide flavor and freshen breath, but it also helps fight bacteria.

No, it doesn’t help whiten teeth so if you don’t have it, no worries! You can leave it out.

All-Natural DIY Teeth Whitening Paste


*Food grade hydrogen peroxide differs greatly from the run-of-the-mill hydrogen peroxide found in the drugstore, which is not safe to ingest as it contains many heavy metals.

  • Mix the baking soda, hydrogen peroxide, and essential oil into a smooth paste.
  • Dip your toothbrush in the paste and brush *gently* for about 2 minutes before brushing with regular toothpaste.
  • Use no more than once a week, since baking soda is an abrasive and you don’t want to damage that enamel!

  1. you can also use powdered Activated Charcoal in the same manner. it was posted on another page and ive tried it. worked very well! :). just open the capsule of powder on your tooth brush, brush on teeth, let sit 2mins or so then rinse well. it might not work as quick as the above method but you may not have the sensitivity problem. Thanks and LOVE your site! 🙂

  2. Hi, Victoria. I would be concerned that the lemon juice would damage the tooth enamel, which can cause some major dental issues.

  3. Hi, Cari! Yes, I have also seen this before! I use activated charcoal topically (it works wonders for your skin) so have some on hand and will need to give it a go. Thanks for mentioning it! And a big thank you for the compliment 🙂

  4. Be careful, my dentist friend told me not to do this. It will take a toll on your enamel. If you do it make sure the peroxide exposure is short. You will see whitening by adding just a bit of baking soda to your toothbrush (I put it on my toothpaste, a Jason one that is fluoride and sls free) once or twice a week and have very white teeth.

  5. Hi, Katie. Thanks for your comment! This is a valid concern, but I think it is debated. Most store-bought whitening agents contain peroxide (“white strips” etc.). According to the EU’s public health department, “a few studies focussing on effect on surface structure and chemistry have shown a degradation of the tooth surface associated with the whitening process… It should also be noted that soft drinks (e.g., Coca-Cola, Pepsi Cola) and fruit juices also cause demineralisation and alteration of enamel comparable to those reported for whitening products.” They then go on to say, “studies measuring potential effects of tooth whiteners at the microscopic scale have shown no or very little effects on hardness and structure of dentin or enamel.” Link: The American Dental Association also mentions that “Data accumulated over the last 20 years, including some long-term clinical study follow up, indicate no significant, long-term oral or systemic health risks associated with professional at-home tooth bleaching materials containing 10% carbamide peroxide (3.5% hydrogen peroxide).” Link:

  6. Hydrogen Peroxide used to be used for cleaning wounds too, but it’s no longer recommended unless it’s done with medical supervision because it’s supposed to break down the tissue. That could explain the sensitivity too. I’m not sure what a “safe” interval is for use. Since some people have soft enamel and other have problems from dry mouth, as in Sjogren’s, the best bet is to ask your dentist. I have used it carefully and for a short brushing without a problem, but I never do it often. Hope this helps.

  7. I like to mix peroxide with unflavored/unsweetened gelatin. I let it set up like jello, and just use a tiny spoon size of it. I usually do this just before getting into the shower. It seems to “grow” the longer you keep it in your mouth, and it’s easy to spit out in the shower.

  8. Use one or two teaspoons of coconut oil. That whitens very well and detoxifies your mouth. I put one or two teaspoons in my mouth and swish for about 20 minutes. No one knows that I am a smoker and am “supposed” to have yellow teeth.

  9. Is it Baking Soda or Powder? When you click the link it takes you directly to Aluminum free baking powder,

  10. Using baking soda more than once a week not only severely scratches your enamel, but erodes it as well. Doctors recommend using less than once a week, once every two weeks preferably. Hydrogen peroxide is safe to use daily, especially as mouth wash.

  11. Make sure it is “Food Grade 35% Hydrogen Peroxide” (health food stores sell it) that you then dilute 1:11 with distilled water. Do not use 3% Hydrogen Peroxide….way too strong and will hurt the tissues.

  12. Did anyone have a bad reaction with their gums using this teeth whitening method? My gums turned white in some spots, and bled! They were sore for a couple days but now back to normal. This can’t be good.. Please help!

  13. Oh no! Hydrogen peroxide bubbles and turns white when it comes into contact with bacteria. Since the mouth is full of bacteria, I’d imagine this is what you are seeing. As for the bleeding, I don’t know – I’d say maybe brushing too hard (which combined with the granular baking soda could irritate your gums) or maybe you’re just sensitive to baking soda. Do you ever used baking soda on your skin – are you sensitive to it?

  14. Ok- feeling a lot better about the white reaction after reading this! A skin patch test is a great suggestion being that I do have skin on the more sensitive side. The possibility of brushing too hard with granular baking soda makes a lot of sense too.
    Otherwise my teeth are definitely noticeably whiter! Thank you for responding!

  15. I asked my dentist about this and he said both baking soda and charcoal can take off your enamel. Lemon juice is to acidic. He recommends the strips once every 6 months. I am all for natural and wanted to share with others.

  16. I’ve never used hydrogen peroxide, what I usually use is the baking soda with the lemon juice extract. It is somehow effective. I think I’ll just stick to this paste.

  17. I was told that if you cut the hydrogen peroxide 50/50 with water that its a safer option. again this will take a while 2-3 weeks to see results but I feel its gentler on your teeth than the store bought white stripes.

  18. I tried this recipe and it was very runny… So I used 1 Tbsp baking soda and 1 Tsp food grade peroxide with a few drops of peppermint oil. Seems to be the perfect consistency. Is it suppose to be runny?

  19. It can be kind of hard to get them to mix into a paste (did you baking soda settle to the bottom)? You can add more baking soda if you’d like.

  20. I accidentally bought Food Grade 35% Hydrogen Peroxide. Can I still use it, perhaps in a smaller amount? Or should I buy the 3%?

  21. Nadia! Where did you get the great little glass jar from the pic? I love the top to it but couldn’t find one like it on amazon. Please let me know!

  22. I saw a post saying to use distilled water… Do not use distilled water. It absorbs minerals that it comes in contact with I.e. Your teeth. Have you ever seen the effect of distilled water on concrete. It dissolves it!

  23. Did it come off eventually? It’s most likely the peroxide reaction with the bacteria in your mouth, between your teeth – it fizzes up and becomes white.

  24. Thanks for share this post. I had yellow teeth problem before I used charcol tooth polish and i got good result.

  25. Hi I think that this is a great idea for a tooth whitener but I also think lemon juice and baking soda works to I asked my dentist and they said that lemon juice and baking soda is fine and does not damage the enamel at all

  26. Just FYI this ratio will BURN your mouth if your peroxide is a true food grade. I don’t think you really got food grade. Just FYI, I just mixed your concoction and my gums are burned white after seconds. I HIGHLY recommend you delete or revise this post. Truly pure, food grade hydrogen peroxide will burn your skin, and an equal amount of baking soda is NOT enough to dilute it. I wasn’t thinking about that when I looked at your recipe (I should have remembered) and within seconds my mouth was burned

  27. I specify 3% in the post. What percentage were you using? Percentages can go up into the 30s, and yes this would not be advised.

  28. The peroxide you linked to IS NOT FOOD GRADE. It is MISLABELED. Food grade should be 35% that one is 3% like regular peroxide :/

  29. I wouldn’t use both baking soda and peroxide together. Years ago I used knox gelatin and peroxide. It worked pretty well. Now I just make my own toothpaste and I add activated charcoal to it. I think my teeth are just as white w/o having to use anything else. Of course, as I say it’s been a while since I’ve done the peroxide and I wonder just how much whiter they can possibly be? Both activated charcoal
    AND peroxide treatment…. hmmm, maybe they’ll glow?? LOL

  30. Re: the comment about not using distilled water: you must not use tap water to dilute h2o2, as the chlorine reacts with it and reduces its effective concentration. Either use filtered or distilled water at a ratio of 1:11 to dilute 35% concentration down to 3% (same as what you’re probably used to in the dark brown bottles). Most commercial tooth whiteners are between 15-35% concentration in a gel and say to keep them on the teeth for 30 minutes. I’m interested in the idea one commenter wrote about mixing gelatin with 35%, as it might create a stronger gel than an aloe+glycerine blend. Lots of good ideas. Thanks for this post & all the comments!

  31. For Jamea – it’s true that a lot of food grade peroxide is 35%, however it is not the concentration that makes it food grade. The difference between “topical use only” and “food grade” peroxide is the use of preservatives that contain heavy metals which should not be ingested. Thus, you can get food grade peroxide that is 3%, 35%, or anywhere in between. Hope this helps!

  32. Very simple tips but so effective when it comes to teeth whitening treatment. Thanks for sharing the good ideas here. This was totally awesome!

  33. I tried this and I am very happy with the results even after the first try. Can’t wait to see if the results are even better next week! It did sting a wee bit, but nothing like those expensive white strips!

  34. I love my recipe, leaves my mouth fresh and feeling great. I make a big batch.
    1/2 cup coconut oil
    1 TBS baking soda
    1-2 drops peppermint
    mix all together ( I use a small canning jar)
    For a kick once in a while I’ll add a drop of orange essential oil onto my tooth brush.
