What Mouthwashes are Like Rinsing with Soda?
A patient told us the only soda she drinks is diet and felt her teeth should still be protected since the soda is sugar free. So why is she still getting cavities and what does soda have anything to do with mouthwash? Glad you asked.
The Science
The bacteria in your mouth cannot start creating cavities UNLESS it is in an acidic environment from 0-5.5pH.
It does not matter if the food or drink you put in your mouth has "zero sugar," you still can get cavities if your mouth is bathed long enough in acids. On average it takes your mouth about 1 hour to return from acidic to neutral, or from your mouth getting eaten by cavity-causing bacteria to being protected. Most things we eat or drink cause our mouth to become acidic so the sooner after eating or drinking that we can return our mouth to a more neutral pH the harder it is to get cavities.
The carbonation and/or flavoring not only in diet soda but all drinks (juices, sports drinks, energy drinks, regular soda, and water bottles) are ALL acidic. So if it makes illogical sense to use those drinks as a mouthwash, why would you do the same for any mouthwash that is just as acidic as soda?
Mouthwash and Acidity
We suggest everyone use mouthwash because they have huge advantages. They reach areas that floss and toothpaste do not. Particular mouthwashes aid in treating gingivitis, bad breath, cavity formation and prevention, etc. Though mouthwash should never replace brushing and flossing it is an excellent adjunct in caring for your teeth.
However.
Most mouthwashes on the market are acidic. This means that though some effectively kill off bacteria that cause cavities, their acidity creates an environment for the same bacteria to grow back even faster and almost nullifies what you're trying to accomplish.
Mouthwashes to AVOID that are Acidic Enough to Cause Cavities
The pH of every one of these mouthwashes are in the acidic range under the 5.5pH that cause cavities. Surprisingly most of these are popular mouthwashes from Listerine, Colgate, Scope, and even the natural mouthwash like Toms of Maine or Natural Dentist. If you're going on a trip or something short these are fine, but if this is part of your regular daily routine then consider a different mouthwash.

The Top 3 Mouthwashes (regarding pH)
If you are using mouthwash to avoid cavities then the better ones hands down are the more alkaline mouthwashes ranging from 8.01-9.82 pH. This is what Dr. Nelson endorses: Plax, Therabreath, or CTx3. All 3 are amazing and offer additional benefits to preventing cavities, treating gingivitis, antibacterial, loosen plaque, and address bad breath.
Conclusion
This study only focuses on acidic levels of mouthwashes and does not discuss the benefits of particular ingredients (Article on June 2022). Those benefits are trumped by how acidic a mouthwash is though. Know that nearly all mouthwashes have their benefits if used in short-term spurts. However, if your goal is to do all you can to not get cavities, we suggest using a mouthwash that does not foster cavity-causing bacteria to quickly grow after mouthwash use. Any of the outlined "good" mouthwashes fill that role though the best 3 mouthwashes in this case are Plax, Therabreath, or CTx3 from Carifree.
