"Toothpaste.
I'm sure you use tooth toothpaste or rather, I hope you do.
Maybe you use commercial toothpaste, you know, the kind you buy in the store or maybe you make your own toothpaste.
Some people do.
You know it's not very common.
I think if you make your own toothpaste, it might not taste very good, but that's not important for everybody.
What is toothpaste? Well, basically it's a mild abrasive.
You're trying to scrub your teeth and the brush is pretty good.
You can use a toothbrush to scrub your teeth.
I read about it.
Um, a case in Africa where people used sticks to clean their teeth and that might work too, but most people use a toothbrush and the toothbrush is ok.
But if you use the mild abrasive toothpaste, it cleans where the brush isn't actually directly touching.
Now, I heard from a student years ago he didn't use toothpaste.
He was afraid that it was going to wear his teeth down.
It was quite interesting because he was kind of um, a little bit older and his teeth looked fine.
It looked like they had lots of enamel left.
I don't think he really had to worry about wearing his teeth down.
He'd probably come to the end of his life before his teeth came to the end of theirs.
But he was worried about that and some people do worry.
I don't think you need to though.
If you brush crazy too much, you might have to worry.
But once or twice a day with toothpaste is not going to wear your teeth down in your lifetime.
Don't worry about it.
What's in these toothpastes? The big big thing in toothpaste is baking soda or something similar to it.
It doesn't quite dissolve easily in water, although it does a little bit and it stays as little Granules and they can scrub your teeth.
The other day.
I bought a toothpaste about a year ago and I discovered after I bought it, it had little tiny micro plastic particles in it to help clean your teeth.
Now, that's terrible for the environment.
So please don't buy toothpaste with plastic microparticles in them.
Now, I've kind of run out of time but toothpaste.
Gee, I could talk all day about it.
Thanks for listening."
