Everyone loves white teeth, but many conventional teeth whitening systems out there make our teeth more sensitive and even damage the enamel. OUCH. I know in high school I used the heck out of Crest Whitening strips and am paying for it now with very sensitive teeth. There is good news though. You can create your own DIY whitening toothpaste for sensitive teeth. In fact, not only will it not damage your teeth, but it can also help remineralize them, making them stronger in the long run.

(This post probably contains affiliate links. Read my full disclosure here.)
But first, here is a little back story on traditional whitening toothpastes.
On one of my many trips to the dentist I asked her about my sensitive teeth and she said they likely kept hurting because I was using whitening toothpastes. Not strips. Not whitening paste. But just plain whitening toothpaste.
Why? Because the ingredients in the toothpaste act like sandpaper on a porcelain tub…the tub being our teeth. Once our teeth enamel is gone, it’s gone.
Yes, we all want white teeth for our graduation, wedding day, or some other special event. But long term use can cause irreversible damage to our teeth that makes it not worth it. A better choice would be to avoid food and drink that stains the teeth, sorry coffee and wine lovers. If that’s too extreme there are plenty of natural teeth whitening remedies out there, such as strawberries. In fact, I wrote a whole post on how to whiten your teeth naturally.
But today I’m taking it a step further. I not only have a DIY whitening toothpaste that will gently brighten your teeth, but can also help remineralize them if they are super sensitive.
DIY Whitening Toothpaste for Sensitive Teeth
- 3 tbs baking soda
- 3 tbs coconut oil
- 3 tbs Diatomaceous earth – USDA food grade only!
- 10 essential drops oil of peppermint
- Stevia
How To Use DIY Whitening Toothpaste:
- Mix all ingredients until well blended. Store in a glass container with a lid.
- Now, simply dip your toothbrush in the mixture, brush as you normally would, and rinse.
Let’s talk about the benefits.
Why Coconut oil?
It contains antibacterial and anti-fungal properties. Not only does it attack the harmful bacteria in your mouth, but it can also reduce plaque, prevent tooth decay and fight gum disease. As an added benefit you could try oil-pulling in the morning.
Why Baking Soda?
It tackles bad breath as well as provide a mild abrasive to remove stains.
Why Bentonite Clay?
Bentonite Clay cleans bacteria and absorbs it like a magnet. If interested, here is my favorite face mask I make with Bentonite Clay. TRY IT. Your skin will look amazing after.
Why Stevia?
Stevia helps make it sweet and provides anti-cavity protections.
Why Peppermint?
Peppermint tackles bad breath and helps you feel minty fresh.
Lastly, if your teeth need an extra boost I do recommend Sensodyne for sensitive teeth but make sure it is NOT the whitening kind. I am also a huge fan of Trader Joe’s toothpaste.

Thank you for sharing this!!! I have very sensitive teeth so I will have to try this out!!! I never would have thought of using these ingredients together!
Diane – I hope it works for you!
I made this 2 days ago. It’s hard. How can you make it pasty? I tried adding glycerin but it made it worse. Any suggestions??
If you want it pastier add more baking soda. Good luck!
This is perfect. I am trying to eliminate as many chemicals from the products i use or eat so this will help.
Yesss. Same
I need to try this! My teeth are so sensitive!!
I’m so going to try this!!! So awesome!!
So is benenite clay the same thing is diatomatious earth? I use baking soda to brush right now, but I should probably give this a try too.
Yes, they are the same!
This is great! I’ve been in the same boat with trying to over-whiten and getting sore gums! Natural is the way to go :)
Ooo I really like this idea. I want to whiten my teeth so bad, but hate the chemicals in whitening strips etc. I’ll have to give this a try.
Love it! I have sensitive teeth, so the store bought brands often cause me pain.
I love this! And it’s all natural and less expensive. I learned a while back that these things can be more harmful than helpful. Thanks for sharing.
Interesting! My husband has really sensitive teeth so I might make this for him to try.
Yess! I hope he likes it.
This is a great recipe! I need to get that clay, I have some for my face, but I’m unsure if it’s food grade.
It probably is. I use the same clay for both :)
Very cool, and looks very easy to make!
I have sensitive teeth so I have to be careful what I use. Thanks for this tip, I may just have to try it out!
I have to be super careful, too. That’s why I avoid traditional whitening products!
OMG this is genius! I have semi sensitive teeth but most whiteners don’t bother me – although I’d love to try a DIY one!
Oohh you are lucky then!
this toothpaste looks amazing! I could even add my favorite essential oils!
Love al the natural ingredients. Coconut oil to the rescue again! Thanks for the tip!
I didn’t realize you cam make our own toothpaste!
