DIY pH Balancing Mouth Rinse

Let’s face it: Some of the most delicious and frequently consumed beverages are often some of the most damaging to the teeth.

If you start your morning with coffee, end the evening with red wine, and have some “healthy” kombucha or tea during the day, you are creating multiple opportunities for enamel erosion due to the high acid content of those beverages.

In addition to causing the breakdown of enamel, making them more susceptible to decay, an acidic environment allows bacteria to flourish. These bacteria then contribute to a host of dental and oral health issues, including bad breath, gingivitis, and, of course, the formation of cavities.

I recommend minimizing your consumption of acidic drinks as much as possible, but you don’t have to give them up for good. You just need to counteract the acid from the foods and drinks you consume.

While optimal pH for the blood is 7.4, the saliva should be around 7.1. It’s slightly more acidic to begin the digestive process. However, acidic foods and drinks will drive the acidity of your saliva to a level that actually begins to contribute to the issues I mentioned above.

One of the best ways to minimize the acidic effects of coffee, wine, and other substances is to rinse with water after consumption. But I developed this recipe as an even better alternative.

In addition to neutralizing the acid from popular drinks, this mouth rinse will actually help to rebalance the pH of the mouth, creating a more alkaline environment that supports a healthy, well-balanced microbiome.

The star ingredients of this recipe are algae, a natural alkalizer that also moisturizes the mouth, and baking soda, which also works to neutralize acid in the mouth.

Whip up this easy recipe and be sure to keep some handy for a quick rinse after consuming acidic foods and drinks!

  1. When I made this my saliva was still acidic (6-6.2). I added 2tsp baking soda and 2tsp Xylitol. This now gives me the alkaline reading (7.6-8) I was after. My dentist suggested an alkalizing mouth wash so I could brush my teeth anytime after eating. As too often I would wait and forget or just not have the time later. Or drink something quite acidic where even rinsing with water might not be good enough to combat the effects. The adjusted recipe is now comparable to the store bought mouthwash I’ve been using with glycerin in it (to be avoided). Which I’m thrilled to be able to replace. Thanks!

  2. Can I skip the xylitol if I do not want it to be sweet or is this part of the pH balance?

    • Mark Burhenne, DDS says:

      Xylitol is an excellent prebiotic so it does have a valuable role.

  3. Thanks so much for this recipe but I have a question. I would love to use this while my Invisalign aligners are in but will it stain my teeth blue green? I don’t care so much about the trays being stained; they get changed out anyway but my teeth are a different matter (obviously!)

    • Mark Burhenne, DDS says:

      Hi Judy!

      For best results, it’s best to remove your aligners first since many of the areas the mouthwash needs to reach are covered by aligners.

  4. I used to get cankers often once and a while as a child. But when I was about 45 I started getting 3 or more at a time very frequently and now at 50 I still get them. I used to use regular mouthwashes several times daily but stopped when I started getting the sores, so I have been not using it for 5 years now. Is it possible, that I am getting the sores because I killed off too many good bacteria? I am desperate for an answer as some weeks my cankers are almost debilitating

    My son struggles with canker sores. I understand that cankers are still somewhat of a medical mystery, but I’m curious what your thoughts are on then, what you recommend to your patients and/or how you treat them, and if you think this mouth rinse will help by restoring a healthy pH, thereby eliminating the possible culprit? Thank you!
