When it comes to home maintenance often it's a bad habit that causes problems as opposed to parts, products or systems that just stop working. In both my plumbing class and my home maintenance class I stress the point that you should never use your toilet as a trash can. Just because the packaging says it's 'flushable' doesn't mean it won't clog your drains.
Do NOT put hair, q-tips, dental floss, cleaning wipes, feminine products or anything other than toilet paper into your toilet.
Here is an article about the problems that dental floss being flushed down toilets caused for the city of Toronto. I can't make this stuff up.
