Why can a water flosser make your gums bleed?

Bleeding with a water flosser can happen when gums are inflamed or the jet is used too forcefully; persistent bleeding needs a gum examination.

How can plaque cause bleeding during cleaning?

Plaque at the gum margin can trigger gingival inflammation, making tissue bleed when cleaned. A high pressure setting, a tip held too close, or a recently injured gum can also contribute.

How should you use the jet when gums bleed?

Start at a low setting, aim along the gumline rather than into the tissue, and move the tip slowly around each tooth. Clean daily and note whether bleeding and swelling are improving.

When should ongoing gum bleeding be examined?

Arrange a dental visit for bleeding that persists, spontaneous bleeding, bad taste, loose teeth, recession, or facial swelling.

What causes of bleeding should you discuss with a dentist?

Ask whether plaque, calculus, periodontal pockets, a bleeding disorder, or medication could explain the symptom and which tip and pressure are appropriate.
