Toothpaste is another common culprit of clogged drains. Like soap, toothpaste is made up of oils and fats that can solidify over time and cause a blockage.  A drain strain will also help prevent toothpaste from causing clogs, catching it before it has a chance to enter your pipes. You should also be careful about what kind of toothpaste you use, as abrasive types can damage your pipes.
