Gums · Perivale, Ealing

Bleeding Gums. Why it happens and what helps.

Gums that bleed when you brush, floss or eat are the most common sign of gum disease. Caught early, it often settles with better daily cleaning and a professional clean, which I can provide without a dentist’s referral.

What’s going on

Why gums bleed.

Bleeding is a sign of inflammation. In most people it starts with plaque, the sticky film of bacteria that builds up along the gumline when it isn’t fully removed.

Inflamed gum tissue is fragile, so it bleeds at the lightest touch from a toothbrush or floss. The bleeding itself isn’t the problem; it’s the signal. Left alone, the inflammation can spread below the gumline and start to affect the bone that supports the teeth.

Common causes

  • Plaque along the gumlineThe main cause. Plaque that isn’t removed irritates the gums and can harden into tartar.
  • SmokingA major risk factor for gum disease, and a reason to have your gums checked regularly.
  • PregnancyThe NHS advises extra dental check-ups during pregnancy, because gum problems are more likely.
  • Type 2 diabetesAlso linked with gum disease. The NHS advises extra check-ups if you have it.

At home

What helps, and what to avoid.

Do

  • Brush twice a day with a fluoride toothpaste, at the gumline
  • Clean between your teeth daily, using interdental brushes or floss
  • Keep going even when it bleeds: inflamed gums usually bleed less as they get cleaner
  • If you smoke, ask for support to stop

Avoid

  • Don’t brush so hard that it hurts
  • Don’t stop cleaning between your teeth because they bleed
  • Don’t rely on mouthwash instead of brushing

At your appointment

What I check when your gums bleed.

  1. Where it bleeds

    I gently measure around every tooth and note exactly which areas bleed. A pattern often shows which spots your brush or floss is missing.

  2. Pocket depths

    The depth of the gap between gum and tooth tells me whether this is early inflammation or gum disease that has gone below the gumline.

  3. Tartar and fillings

    Hardened tartar and the rough edges of old fillings trap plaque. Both are easy to miss at home and easy to fix professionally.

  4. Your health and medicines

    Some medicines and conditions affect how gums bleed and heal, so we go through these before any treatment.

Bleeding Gums FAQs

Questions about bleeding gums.

Something else on your mind? Email me or call 020 8997 0933.

Are bleeding gums serious?

Bleeding gums are a common early sign of gum disease. Caught early, the inflammation often settles with better cleaning and a professional clean. It’s worth having them checked, because gum disease that isn’t treated can damage the bone that holds teeth in place.

Should I stop flossing if my gums bleed?

No. Bleeding usually means the gums are inflamed, not that cleaning is harming them. Keep cleaning gently every day. If the bleeding doesn’t settle, book a check so we can find the cause.

Can a hygienist treat bleeding gums without a dentist?

Yes. Under GDC direct access you can book a gum assessment and treatment with a hygienist or therapist directly. If anything needs a dentist, I’ll explain and refer you on.

Why do my gums bleed more during pregnancy?

Gum problems are more likely during pregnancy, and the NHS advises extra dental check-ups while you’re pregnant. Tell me when you book if you’re pregnant.

My gums bled once after flossing. Do I need an appointment?

An occasional spot of blood after cleaning hard isn’t usually a concern. Gums that bleed regularly when you brush, floss or eat, or that look red and swollen, should be checked.
