When you flush toilet paper down the toilet the toilet paper dissolves which makes it very easy for the toilet paper to travel down the sewer pipes.
When you put toilet paper into the toilet with water in it the water starts dissolving the toilet paper as soon as you put it in the toilet.
So as long as you don't flush a lot of toilet paper down the toilet at one time it should never clog the toilet.
Toilet paper is designed so that it can be flushed down the toilet so you should always flush dirty toilet paper down the toilet which is the best way to dispose of toilet paper.
I used to work in a store and people used to put toilet paper into the trash cans in the bathroom stalls and that was gross.
We had to put a sign in the stalls to please flush the toilet paper and not put it in the trash.
