how does listerine work?

Antiseptic: Listerine works based on the 'essential oils' it contains. These essential oils act as an antiseptic to kill off the bacteria in the mouth that cause tooth decay and gum disease. Listening is a good product, but it should be used in addition to brushing, not instead of brushing. Also, smokers should use an alcohol-free listerine if that is the brand of mouthwash they choose.

Kills bacteria: The alcohol in listerine kills bacteria.

A 38-year-old member asked:

That listerine bottles warn not to swallow it. What could happen if someone swallows it?

A little is OK: You really shouldn't swallow listerine on a regular basis. But if you happen to accidentally swallow a bit you should be fine. People who are alcoholics have been known to drink scope when they can't get any of their regular stuff. Listerine has ingredients other than scope that would probably cause liver and/or kidney damage if you drink enough of it.

Is listerine still effective if it is not left in for a full 30 seconds?

Yes, but...: Listerine like any other oral health product is tested clinically before releasing it to the public. The studies use certain parameters (such as using the mouth rinse for 30 seconds). Yes it starts the moment the chemistry begins working, but you may not achieve the results achieved in the clinical tests (the full claimed benefits on the packaging) if you don't follow the directions exactly.

Might get sick: Depends on how much. It can be up to 19% alcohol, so not so good. The mix of everything might give you a stomach problem or cause you to vomit ... Or it might do nothing. If you have swallowed a small amount, probably nothing. More, then i would drink lots of water to dilute it . Can't speak from personal experience. Might look at the bottle or check web site.

Addict: You are an alcoholic. I say that without malice or judgement. But this is no different than any other alcoholic looking for a buzz from some other odd products. Pease get to your doctor to discuss or find a.A.
