Mouthwashes have long bragged about killing 99.9% of germs in your mouth, but researchers suggest this scorched-earth approach may harm oral health by eliminating beneficial bacteria along with the bad.
A study found that a naturopathic mouthwash containing herbal ingredients could selectively target disease-causing bacteria while preserving the protective microbes that help maintain healthy gums and teeth.
"It's a paradigm shift," said Georgios Kotsakis. "We're moving from eradicating all bacteria to focusing on selectivity. We want to keep the good bacteria alive while targeting the bad."
The researchers tested a natural mouthwash called StellaLife VEGA Oral Care rinse against two conventional products: the prescription mouthwash chlorhexidine and Listerine Cool Mint.
They exposed various oral bacteria to each rinse and monitored their growth over several days.
The natural rinse significantly reduced populations of harmful bacteria such as Fusobacterium nucleatum and Porphyromonas gingivalis, while allowing beneficial species such as Streptococcus oralis and Veillonella parvula to survive.
Chlorhexidine and Listerine showed no such selectivity, eliminating beneficial and harmful bacteria alike. Chlorhexidine was particularly aggressive, reducing some beneficial bacteria populations by a million-fold.
"These good bacteria have important functions," Kotsakis said. "They synergize with your tissues. They actually kill some of the bad bacteria themselves."
Petri-dish results don't necessarily translate to mouths full of teeth, saliva and dietary sugars, Kotsakis said. The study didn't measure cavity formation or bleeding gums in people.
"Randomized clinical trials are the next step," Kotsakis said.
The work fits an expanding effort to manage oral microbes rather than carpet-bomb them. Heavy use of strong antiseptic rinses has been linked to shifts that may raise blood pressure or blunt nitric oxide signaling.
For those who use mouthwash, the goal should be reinforcing the mouth's natural defenses, not destroying them, he said.

xylitol added to ones mouthwash is another great way to improve oral health:
grok3: Xylitol improves oral health by:
Reducing Cavity-Causing Bacteria: Xylitol inhibits the growth of Streptococcus mutans, a primary bacteria responsible for tooth decay, by preventing it from metabolizing sugars and producing acid that erodes enamel.
Decreasing Plaque Formation: It reduces plaque buildup on teeth, as bacteria struggle to adhere to tooth surfaces in its presence.
Stimulating Saliva Production: Chewing xylitol gum or consuming xylitol products increases saliva flow, which helps neutralize acids, remineralize enamel, and wash away food particles.
Lowering Acidity: Xylitol is non-fermentable, meaning it doesn’t break down into acids like sugar does, maintaining a neutral pH in the mouth.
Promoting Remineralization: By fostering a less acidic environment, it supports the natural repair of early tooth decay through enamel remineralization.
Studies suggest regular use of xylitol (e.g., 6–10 grams daily via gum or lozenges) can reduce cavity risk by up to 30–85%, depending on frequency and dosage. It’s most effective when used consistently after meals.
Herbal remedies. Be very careful. If they use ephedra, watch out.
You should gargle/swish Hydrogen Peroxide around in your mouth instead of mouthwash. Your teeth will thank you.
interesting
Good advice.
.
Xylitol kills my gut- was taking a rinse for dry mouth due to meds, and kept having stomach problems- stopped the rinse, and it went away. (No I don’t ingest the rinse, but you can’t help getting the ingredients into stomach through normal swallowing after rinsing). I just keep a bottle of power aid by bed now for the dry mouth and sip it-
How is that possible?
Bacteria are bacteria.
What makes this product allegedly selectively kill specific species?
I would welcome it if it could get rid of my oral thrush.
Been battling it since I was in hospital.
Even better, colloidal silver.
