Snoop's Take

Listerine Cool Mint Antiseptic Mouthwash for Bad Breath, Plaque and Gingivitis is designed to kill germs and refresh your breath in a cool, minty blast. It promises to help prevent plaque and gingivitis while leaving your mouth feeling clean and revitalized. The community debates this product with no shortage of colorful opinions. Some users champion its germ-fighting capabilities, with one user noting, "Don’t use alcohol based mouth washes anyway (at least according to dentists)." Others, however, decry the burning sensation and harsh drying effects, claiming that its high alcohol content can lead to more harm than good. The conversation is split, with passionate endorsements countered by stark warnings about irritation and disruption of the oral microbiome. In summary, while Listerine delivers on its promise of fresh breath and germ elimination, the prevailing sentiment suggests caution for those with sensitive mouths; it is a solid choice if you can tolerate its drawbacks, but expect a polarizing experience in the oral care arena.

If you have issues with gingivitis, Listerine Gum Therapy.

Positive Feedback

Use alcohol if you need an antiseptic otherwise it can dry your mouth out and cause dysbiosis.

What it does well!

Key strengths users can’t stop talking about.
Effective for gingivitis treatment
If you have issues with gingivitis, Listerine Gum Therapy.
If your only concern is gingivitis then I would opt for Listerine gum therapy.
Helps eliminate germs and bacteria
But mouthwash also helps with the elimination of germs, bacteria, and viruses... and should be used as an extra measure to daily dental hygiene.
True anti bacterial mouth wash protect.
Effective for killing germs causing bad breath
General consensus that I've gathered is that it's not good due to the drying effects on the mouth caused by the high concentration of alcohol.
That stuff can be pretty vicious.
Provides a cool mint taste
I am sorry you weren't forewarned about the taste issues, but spitting out different coloured saliva after rinsing with a coloured liqued is a sign of mild caution.

Where it needs some work!

Areas to watch—feedback on possible improvements.
Alcohol can dry mouth
Use alcohol if you need an antiseptic otherwise it can dry your mouth out and cause dysbiosis.
Don’t use alcohol based mouth washes anyway (at least according to dentists).
Not sure how anyone could mistake the burn of alcohol for mint flavor lol.
Listerine dries out your soft tissue, inhibits saliva flow, washes away the mineralising agents in your toothpaste and kills good bacteria.
Burning sensation from alcohol
Probably because it makes sense of the burning astringent sensation from the alcohol.
Why does Listerine burns I noticed a sharp burning sensation while using Listerine.
My dentist and hygienist, do not recommend Listerine unless you have a bad case of gingivitis.
It's not as effective as regular, alcoholic mouthwash, but it's probably better than nothing.
Sensitivity with gums
It does still sting where my gums are sensitive though!
Mouthwash can disrupt oral microbiome balance
Those products are harmful to the oral microbiome balance.
Acidic nature of mouthwash may be harmful
I think it only protects the teeth for a few min until the pellicle reattaches and the new biofilm layer forms.
Much to my dismay, I just recently found out that Listerine is acidic.
Mouthwash shouldn’t be acidic- needs to have a pH of 7 or higher.
Alcohol can dry out mouth
Just avoid alcohol-based mouthwashes as these can dry out your mouth too much and basically wipe completely bare your entire spectrum of mouth bacteria.
Temporary solution for bad breath
It's like applying paint on a wall that is rotten and crumbling from the inside.
Not a substitute for brushing teeth
They cover the bad breath but nothing beats brushing teeth.
9 out of 10 redditors recommend brushing.
Brush teeth + clean tongue.
Can lead to canker sores and PH imbalance
I normally get canker sores when I use it too much, since I think it fucks up the PH balance of your mouth.
Can cause irritation/dry mouth
But it does burn and can cause irritation/dry mouth.
