Bleeding gums: what to do at home, and when to see a dentist

In short: Gums that bleed when you brush usually mean plaque at the gum line. Keep brushing gently twice a day, clean between your teeth every day, and see a dentist. Get an urgent appointment if teeth are loose or gums are very swollen.

Bleeding when you brush or floss is the most common sign of gum disease (NHS). It usually starts with plaque at the gum line, and the gums can recover if you clean that plaque away every day (MedlinePlus). This guide covers what to do right now, how to clean so your gums settle, and when to see a dentist, with UK, German and US advice side by side.

Ask for an urgent dentist appointment if your gums are very sore and swollen, a tooth feels loose, or you have ulcers, red patches or a lump in your mouth or on your lip (NHS). In the UK, call 111 if you can't reach a dentist.

What do you want to do?

Your gums are bleeding now

Press, then spit, don't rinse. Start at Right now.

They bleed every time you brush

Gentle cleaning at the gum line. Go to Clean so they settle.

You're not sure if it's serious

Check the signs and book a dentist. Go to See a dentist.

Right now

  1. Don't panic, and don't scrub harder.

    Illustration

    Brushing too hard is one cause of bleeding gums (MedlinePlus). Brush gently with a soft-bristled brush instead.

  2. If it keeps bleeding, press a pad of ice-cold gauze on the spot.

    Illustration

    MedlinePlus says you can control gum bleeding by pressing directly on the gums with a gauze pad soaked in ice water.

  3. Spit out the toothpaste, but don't rinse.

    The NHS says to spit after brushing, not rinse, and not to use mouthwash straight after brushing.

Clean so your gums settle

  1. Brush gently with a soft brush, at least twice a day.

    Illustration

    MedlinePlus says to brush gently with a soft-bristled brush at least twice a day, ideally after every meal. Use fluoride toothpaste (NHS). Pressing too hard won't clean better; it just makes sore gums sorer.

  2. Aim the bristles at the gum line.

    Illustration

    Plaque collects mainly where the teeth meet the gums (gesund.bund.de), and plaque there is the main cause of bleeding (MedlinePlus). See how to brush and floss properly for the full method.

  3. Clean between your teeth every day.

    Illustration

    Use floss or interdental brushes every day (NHS). gesund.bund.de says plaque between the teeth can be removed with interdental brushes or floss. MedlinePlus says to floss at least once a day, and its bleeding-gums page suggests twice.

  4. Slide floss in gently. Don't snap it into the gum.

    Illustration

    Flossing the wrong way can make gums bleed (MedlinePlus). Follow your dentist's advice on how to brush and floss so you don't hurt your gums (MedlinePlus).

  5. Keep it up every day for at least a week or two.

    Illustration

    MedlinePlus says bleeding and tenderness should ease within 1 or 2 weeks after a professional clean and good care at home. Without cleaning, plaque can irritate the gums again within a few days (gesund.bund.de).

Habits that help

  1. Don't smoke.

    Illustration

    The NHS says don't smoke. MedlinePlus says tobacco makes bleeding gums worse and can hide other problems, and gesund.bund.de lists smoking as a risk for gum disease.

  2. Cut down on snacking between meals.

    Illustration

    MedlinePlus suggests a balanced diet, avoiding snacks between meals and cutting down on carbohydrates.

  3. Check that dentures or braces aren't rubbing.

    Illustration

    Badly fitting dentures or other dental appliances can make gums bleed. See your dentist if they don't fit well or cause sore spots (MedlinePlus).

See a dentist

  1. Book a dentist if your gums bleed, hurt or swell.

    Illustration

    The NHS says see a dentist if your gums bleed when you brush or eat hard foods, are painful and swollen, or you have bad breath, and if your child has sore, bleeding gums. Gum inflammation often doesn't hurt, so it can go unnoticed (gesund.bund.de). It helps to write down when the bleeding happens before you go.

  2. Go urgently if a tooth is loose or your gums are very swollen.

    Illustration

    Ask for an urgent appointment if gum disease comes with very sore, swollen gums, loose teeth, ulcers or red patches, or a lump in your mouth or on your lip (NHS). MedlinePlus says see your provider if bleeding is heavy, goes on for a long time, continues after treatment, or comes with other unexplained symptoms.

  3. Tell your dentist about any medicines, but don't stop them.

    Illustration

    Blood thinners are one cause of bleeding gums (MedlinePlus), and some medicines make gums grow so they're harder to clean (gesund.bund.de). Never change your medicines without talking to your doctor first (MedlinePlus).

  4. Keep up regular check-ups and cleaning.

    Illustration

    Tartar (hardened plaque) can only be removed at the dentist (gesund.bund.de). Early gum disease is treated with cleaning advice and a clean by a hygienist (NHS). How often you go depends on where you live: see the table.

Questions readers ask

Should I stop brushing if my gums bleed?

No. The NHS says to brush twice a day, and MedlinePlus says to brush gently with a soft-bristled brush at least twice a day. Plaque left at the gum line is the main cause of bleeding (MedlinePlus).

Are bleeding gums serious?

Usually they are an early sign of gum disease, which you can usually reverse with daily brushing, flossing and regular cleaning by a dentist (MedlinePlus). If it goes on, it can spread to the tissue that holds the teeth (gesund.bund.de), so get it checked.

How long until my gums stop bleeding?

MedlinePlus says bleeding and tenderness should ease within 1 or 2 weeks after a professional clean and good care at home. If it doesn't, go back to your dentist.

Why do my gums bleed more in pregnancy?

Hormone changes in pregnancy make gums more sensitive (MedlinePlus, gesund.bund.de). In the UK, NHS dental care is free while you're pregnant and for 1 year after the birth.

Does mouthwash or salt water help?

Only use a rinse your dentist suggests. MedlinePlus says your dentist may tell you to rinse with salt water or a gum rinse, and to ask first because some rinses contain alcohol. The NHS says not to use mouthwash straight after brushing.

Can medicines make gums bleed?

Yes, blood thinners can (MedlinePlus), and some medicines make the gums grow, which makes them harder to clean (gesund.bund.de). Never stop or change a medicine yourself: talk to your doctor first (MedlinePlus).
