Why is it, toothpaste clings to the inside of my drains?

It's not like anyone brushes their teeth, without "wasting" water.
The drains begin to drain slow, then end up stinking.

I was talking to some neighbors, they say they have the same problem.

The drains are nasty, this is pvc pipe. I've cleaned them before, the
stench is overwhelming.


Having last week spent about an hour snaking out my bathroom-sink
drain, I've now taken to spitting toothpaste, phlem (from swishing
with listerine) down the TOILET.

Why? Because the pipe out of the toilet is of MUCH larger diameter,
thus MUCH larger cross-sectional-area to circumference (where the
stuff would stick to it) ratio (is the diameter-squared, that ratio
varies as), thus less sticks and more goes out to the street sewer.










Maybe someone is ****ing in my drains, I dunno, but its ****ing me off.

As long as there's running water taking it out, it all goes the same
place, and does NOT "stick".



I had a dental hygentist say toothpaste is purely optional. *It is the
brush, floss and mouthwash that is important.

Hygienist may have a point.


QUESTION: what do OTHER hygienists and dentists say about this?

What I've heard is that the (hopefully VERY fine) "grit" in toothpaste helps grind-off
the crud from the teeth.

But you do not need much at all; just a tiny amount does the trick (doing it
a la tv-toothpaste-ad just sells MUCH more toothpaste to stick to the
sices of your pipes!)


Again, what do YOU hear from YOUR -- well, DENTISTS?


THANKS!
