Unwanted plumbing issues can be a hassle to deal with, and one way to avoid them is by being mindful of what we flush down the toilet. While many items are commonly known to be problematic if flushed, such as baby wipes or feminine products, dental floss is often overlooked.

It may seem harmless, but the reality is that dental floss should not be flushed down the toilet. Flushing dental floss can lead to clogging and blockages in our home’s plumbing system.

The Dangers Of Flushing Dental Floss

The Dangers of Flushing Dental Floss

Flushing dental floss down the toilet can lead to serious consequences, especially for our environment. One of the major concerns is the environmental impact it has. Dental floss is not biodegradable and can cause harm to marine life and clog sewage systems when it ends up in our rivers and oceans. The accumulation of dental floss in the sewage system can lead to blockages and costly repairs.

Causes of toilet clogging from dental floss are numerous. Its long and stringy nature makes it prone to entanglement with other debris, such as hair and wipes, resulting in pipe blockage. Furthermore, dental floss may get caught in the pumps and machinery at wastewater treatment plants, disrupting their operations. This can lead to untreated sewage being released into the environment, polluting water sources and harming ecosystems.
