Is Bleeding Gums Normal When You Start Flossing? What to Do

The Alarm of Blood in the Sink

You decide to take charge of your oral hygiene, buy a water flosser, and run it for the first time. But when you spit, you notice pink water and bleeding gums. Your immediate reaction might be to panic and put the device away, thinking you've damaged your gums. Don't stop—this is a common reaction, and understanding why it happens is key to overcoming it.

Why Gums Bleed Initially

When you haven't been flossing regularly, plaque accumulates along the gumline and between the teeth. This plaque contains bacteria that cause the gums to become inflamed and sensitive—a condition known as gingivitis. The blood vessels in inflamed gums become fragile and dilated. When you introduce a water flosser, the water jet disrupts the plaque, which can cause these sensitive blood vessels to bleed. The bleeding isn't caused by the water flosser harming your gums; it's a sign that the gums were already infected.

What You Should Do

The solution to bleeding gums is, counterintuitively, to keep flossing. If you stop flossing, the bacteria will continue to multiply, the infection will worsen, and your gums will bleed even more. If you keep flossing daily, you remove the bacteria causing the inflammation. Within 7 to 10 days of consistent flossing, your gums will heal, tighten, and stop bleeding entirely.

Tips for a Comfortable Start

To minimize discomfort during the transition phase, use lukewarm water in your reservoir and start on the lowest pressure setting. The SWSH E30's soft setting is ideal. If the bleeding is severe or does not stop after two weeks of daily use, consult your dentist, as it may be a sign of advanced periodontitis that requires professional treatment.
