There are some things that you always put in the trash. One example is dental floss. It is good that you use dental floss! But please do not flush it down the toilet. Why? Because dental floss really gums up (ha!) the works in wastewater systems. It never breaks down and causes big tangles and clogs in the system. I guess the bottom line is that we do not use our toilets or sinks as trash cans. I can remember that.
