DIY Beauty: using baking soda to whiten your teeth

I’m getting hooked on DIY beauty! Because it’s fun, it’s healthy and it’s cheap! Here’s my experience with using baking soda to whiten my teeth. It works! Okay, don’t expect the sort of sparkling white teeth you see on celebrities but baking soda will take off some of the coffee and tea stains and give you a cleaner looking set of teeth.

Baking soda to brush teeth is safe
This is one of the most popular and safest DIY methods to whiten your teeth naturally. There are some DIY suggestions of using lemon juice or strawberries but those could do more harm by eroding the calcium in your teeth or cause tooth cavities. However, you want to know that baking soda is pretty abrasive on contact. So on some forums, the advice is to dig a toothbrush into the baking soda and then to start brushing. Well, not very good. You’ll find that your gums hurt quite a bit this way. The best way I have found through trial and error is to mix the baking soda with toothpaste.

Baking soda mixed with toothpaste
First, I squeeze some toothpaste on my toothbrush as usual. Then I top it up with a small spoonful of baking soda and start brushing. You can use baking soda only of course but I find that the toothpaste helps to ease off some of the abrasiveness of the dry powder for me.

Whiter teeth in a week
I saw a slight difference after the first brushing using baking soda. Within a week of brushing with this ingredient once a day, my teeth was noticeably whiter. Even my husband noticed and he has started to use it too.

Brushing with baking soda once or twice a week
However, I plan to slow down now that I see results and will probably keep to brushing with baking soda only once or twice a week. This is because I feel that baking soda while safe, is still a mild abrasive cleaner so I don’t want to use it everyday. And by the way, this stuff taste salty!

    does it have to be at room temp.?

    What do you mean? The baking soda?

  3. rosee says:

    but isnt baking soda kinda poisonous ?

  4. Sesame says:

    Why is it poisonous? I’m not aware and I know baking soda is used in food too. However, if you use it in brushing your teeth, you shouldn’t be ingesting a lot too. Plus, many toothpastes actually use baking soda.

  5. Ceomr says:

    You said you brushed your teeth everyday for the first week you started to use it (baking soda). If I do that, how often should I brush my teeth a day? I wonder if it is once a day or each time you brush your teeth.
    Please Reply.

  6. Sesame says:

    Just once a day should be good enough.

    I’ve tried many home whitening remedies, and the only one that seemed to work was brushing my teeth as usual then mixing together toothpaste, baking soda, and salt then brushing my teeth with that. Then I used to Listerine and it burnt like heck, but my teeth are getting whiter.

  9. Sesame says:

    Yes, baking soda does some wonders for whitening to teeth due to staining.

  10. Shak says:

    you have mention ‘ingredients’ in 4th paragraph ‘whiter teeth in a week’ what ingredients do you taking about so if its any ingredients that we must use so can u plz tell us and if i use that on ‘flouride’ toothpaste, would that be allright…

  11. Sesame says:

    Some people avoid flouride because of some issues or alcohol in their toothpastes.

  12. daffy says:

    Bet thats not the first salty taste in your mouth

  13. NaturalHygiene says:

    Baking Soda + Hydrogen Peroxide + Tea Tree Oil!
    Create your own dirt cheap “teeth-paste” by mixing together into a paste (not soupy):
    –Baking Soda for cleaning
    –Peroxide for whitening.
    –Tea Tree Oil to prevent cavities.

  14. Random says:

    How many times exactly do we have to use this in a day?

  15. Sesame says:

    Er…as per normal in terms of your usual teeth brushing frequency.

  16. Tekaset says:

    Hi i was wondering if its ok to let the baking soda touch your gums and and will it work if your a heavy smoker ?

  17. Sesame says:

    It is okay but don’t brush your gums with them cos the soda is slightly abrasive. If your teeth is stained by the smoking, then it might help you.

  18. Gracemae says:

    Where can I get arm n hammer baking soda in Singapore?

  19. Sesame says:

    Supermarket – NTUC or Cold Storage.

  20. kyleyjordan says:

    I did this lastnight. i see the difference. But my gums hurt already. I do have gum sensititvity though. SO if you have what i have, then try not to use it everyday!

  21. Sesame says:

    Yes, agree. It’s pretty abrasive to use this daily.

  22. arslan says:

    i have some whitish material on my teeth near gum area mean bottom area of teeth and also bottom right and left area,would baking soda work for me?reply

  23. Sesame says:

    Can’t say for sure…you gotta try to know cos I don’t know what’s the whitish stuff on your teeth.

  24. arslan says:

    Alright…can i try it with H2O2(HPO),i have heard that this works pretty good instead of only baking powder?

  25. noel says:

    Is baking soda safe for my 3 yr. old son?

  26. Sesame says:

    It’s supposed to be safe but I think he’s too young to try it cos he may not like the taste.

  27. Minoo says:

    My gums become sore and occasionally even bleed a little bit after brushing with a paste of equal amounts of virgin coconut oil and baking soda. Is that normal, or should I discontinue with it?

  28. Yeah says:

    Be careful because that means your gums are sensitive . I guess you can continue but just lower it to every three to fourdays.

  29. Sesame says:

    You should reduce the frequency then.

  30. minahil says:

    hi thanks for your tips, so glad i stumbled upon your blog! though i have a query; can i use baking powder instead of baking soda or will it be harmful?
    minahil last post is: a glimpse of reality.

  31. Sesame says:

    No, baking powder won’t work for this. You gotta use baking soda. It’s not harmful but it can be slightly abrasive so I suggest you don’t use it daily.

  32. helper says:

    No its not because your son might swallow it and he can be poisoned and kids under 11 or 13 it depends on their teeth shouldn’t be using it

  33. Amy Astor says:

    Great information, been looking for way to whiten my teeth naturally, thanks!

  34. Julia says:

    Nooooooooooooo don’t do it! My dentist told me this is to abrasive to be using on a regular basis. It will wear down the enamel of your teeth.

  35. Xena says:

    I’ve been using baking soda several times a week for 30 years and my teeth & gums are very healthy. You would have to scrub super hard to brush the enamel away.

  36. Sesame says:

    It depends as some people have gums that are more sensitive. I still don’t recommend it to be used daily.

  37. Sesame says:

    Well, twice a week shouldn’t be too bad. But if you’re uncomfortable, then just stick to toothpaste.

  38. Jordan says:

    I know baking soda is used in tooth pastes, but i know my cousin does it and her teeth are very white!!

  39. Sesame says:

    Yes, they are.

  40. Juliet says:

    Hi,is it any kind of baking soda? any specific soda brand? must be from Arm & Hammer’s brand?

  41. Sesame says:

    No, can be of other brands.

  42. Louise says:

    An old remedy, but it works!

  43. Louise says:

    I agree the substance is salty.

  44. Grimm says:

    I know this is an old post but if you have gum sensitivity try oil pulling to help. Do it before brushing and first thing in the morning. Both my husband and I do it and the dentist was impressed how our gums looked.

  45. Sesame says:

    Thanks for the tip. I have been thinking about oil pulling…maybe I should try it soon.

  46. Lucy S says:

    Thanks for sharing Sesame, really interesting read! I may have to use your recipe! I am willing to try anything to get my teeth pearly white!

  47. Sesame says:

    It’ll help to improve by a shade or two but don’t expect pearly white results though. This ingredient only helps to get rid of temporary stains.

  48. Carolyn says:

    You may have flouridosis. It is calcium deposits in the teeth caused by to much flouride.
