1) The Most Common Cause: Gingivitis

The reason gums bleed is plaque buildup along the gumline. When plaque isn’t removed, it irritates the gums and leads to inflammation (gingivitis). Inflamed gums:

• • Look red or swollen
• • Bleed easily when brushing or flossing
• • May feel tender
• • The good news? Gingivitis is reversible with proper brushing, flossing, and professional cleanings.

2) You’re Not Flossing Regularly

If you only floss occasionally, your gums may bleed at first because they’re inflamed.

Keep flossing daily—bleeding often improves within 1–2 weeks.

3) Brushing Too Hard

Using a hard-bristled toothbrush or scrubbing aggressively can damage gum tissue.

• ✔ Switch to a soft-bristled brush
• ✔ Use gentle, circular motions (Modified Bass technique)

4) Tartar (Calculus) Buildup

When plaque hardens into tartar, it can’t be removed by brushing alone. You’ll need a professional cleaning.

5) Other Possible Causes

• • Hormonal changes (pregnancy)
• • Vitamin C deficiency
• • Smoking
• • Certain medications (like blood thinners)
• • Systemic conditions (e.g., diabetes)

When to See a Dentist

• • Bleeding doesn’t improve after 1–2 weeks of good oral care
• • Persistent bad breath
• • Receding gums
• • Loose teeth
• • Bleeding gums can progress to periodontitis, which may cause bone loss if untreated.
