Cognitive dissonance - oldbloke's mutterings
On the front of the Listerine SmartRinse bottle it says "Alcohol and sugar free"
On the back, in the ingredients list, is Benzyl Alcohol.
How does that work then?
Because by "alcohol" they mean "ethanol" and "benzyl alcohol" is a different substance altogether?
Benzyl alcohol: C6H5CH2OH
There are a heck of a lot of alcohols in what you consume, but most of it isn't alcohol.
The same can be said about salts/salt, particularly in bacon.
Ah... My speedread of wiki just let me know some of the initial metabolic pathways are the same.
Also that it can be used against headlice, and as a photographic developer...

Whoa there! Backtrack a bit please... what can be used against headlice, Listerine or one of its ingredients? And what exactly does one do with it? This mother of a headlice-ridden daughter needs to know!
A 5% solution of benzyl alcohol is effective against lice, but not the eggs.
It prevents them closing their spiracles, so the solution will have something else in it to clog those up, suffocating the little blighters.
This is an over-the-counter medicine in the USA. No idea about here.

Thanks for that - headlice provide us with a constant battle here. Clear one lot; check the following week; clear that lot; check again a week later; repeat last two points ad infinitum...
You are fortunate. You have a boy. Regardless of what the experts say, girls are far more prone to headlice than boys.
Does it also say?
"Largely a waste of money"
This is not to say mouthwashes are totally pointless, but I dont use them. Proper brushing more than adequate and no mouthwash will be sufficient to compensate for rubbish brushing
He's pretty good at brushing - he gets to to it in the morning, we do it to him at night. He just happens to like mouthwash!
It does no harm so I dont have a problem with it as such. Just a pet hate of mine that when I have spent 15 minutes explaining to someone about their gum disease and how to deal with it they look at me and say "but how about if I just use a mouthwash? " aaaaaargh! If there was an easy answer like that dont you think I would have said it earlier!

You're a dentist or dental nurse? Maybe you can answer a question (if you don't mind, that is). My children have been told conflicting things by different dentiquacks, and we need an arbiter.
1. Brush the gums and the teeth will look after themselves
2. Brush the teeth and don't worry about the gums
Dentist for my sins.
gum disease is down to the bacteria in plaque. Decay is down to the bacteria in plaque converting sugar to acid. So we want it gone from both teeth and gums. I advise having the bristles of the brush half on gum half on tooth at a slight angle towards the gum to ensure the gumline is clean along with the natural pocket that can form there between the two.
obviously if the tooth is bigger than the brush then you need 2 strokes to do the top half as well as the gumline.
Always happy to answer anything but dentistry isnt completely exact and differences of opinion do exist
