Bleeding Gums: Causes, What to Do and When to See a Dentist
This page is general information and does not replace an examination.
Bleeding gums, gums that bleed when you brush, floss or bite into an apple, are the most common sign of gum inflammation caused by plaque[1][2]. It usually improves with gentle, thorough brushing twice a day and daily cleaning between the teeth[1][9], but a dentist should check it, because the same sign appears in periodontitis[1]. Other causes include pregnancy[3], low vitamin C intake[4], inflammation around implants[8] and, when you also bleed or bruise easily elsewhere, a blood disorder[5]. Bleeding that will not stop is an emergency.

Why do gums bleed?
Plaque is a sticky film of bacteria on the teeth. If it is not removed by brushing and cleaning between the teeth, it builds up and irritates the gums, which become red, swollen and sore and bleed easily[1]. This is plaque-induced gingivitis. Bleeding when the gum is gently probed is so typical of it that dentists use bleeding on probing as the main sign in their definitions of gum health and gingivitis[2].
Gingivitis can be reversed: gum health can be restored once the inflammation is treated[2]. The same bleeding can, however, also come from periodontitis, the destructive form of gum disease, which is why bleeding gums should be checked by a dentist rather than ignored[1].
Stages, deep cleaning and the treatment of periodontitis are explained in our separate guide to gum disease. This page is about the symptom: what bleeding, swollen, sore or itchy gums can mean and what to do.
Possible causes at a glance
| Possible cause | Typical clue | What usually helps |
|---|---|---|
| Plaque-induced gingivitis | Bleeding on brushing or flossing; red, swollen gums[1][2] | Thorough brushing, daily interdental cleaning, professional cleaning[1] |
| Periodontitis | Bleeding plus bad breath, gums shrinking back or loose teeth[1] | Examination, pocket measurements, X-rays and stepwise gum treatment |
| Brushing too hard | Bleeding after forceful brushing; the NHS advises not brushing so hard that the gums bleed[11] | A soft, gentle technique |
| Pregnancy | Bleeding on probing is common and tends to increase through pregnancy[3] | Careful home care; tell your dentist and midwife or doctor |
| Low vitamin C intake | Bleeding tendency where blood vitamin C levels are low[4] | Ask your doctor before taking supplements |
| Gum inflammation around an implant | Bleeding on gentle probing around the implant[8] | Cleaning around the implant and a dental check |
| Blood disorder | Bleeding or bruising easily elsewhere, for no reason[5] | See a doctor promptly |
Several causes can exist together. Blood-thinning medicines are a separate case: do not stop or change them because your gums bleed; tell your dentist, who will consult the doctor who prescribed them.
What to do now
If your gums bleed when you brush and you have no warning signs (see the next section), these steps are a sensible start:
Keep brushing, gently
Brush twice a day with fluoride toothpaste, including along the gum line; spit after brushing, do not rinse[1]. Avoiding the bleeding area lets plaque build up, and plaque is what irritates the gums[1].Clean between the teeth every day
Use floss or interdental brushes[1]. In a Cochrane review, interdental brushes may reduce gingivitis more than floss (low-certainty evidence)[9].Time your mouthwash
Do not use mouthwash straight after brushing; choose a different time, such as after lunch[10].Do not smoke
Not smoking is part of the NHS advice for preventing gum disease[1].Book a check-up
Have your gums examined, and a professional cleaning if plaque and tartar are present[1].
Bleeding from plaque-related inflammation often lessens as the gums heal, but only an examination can rule out periodontitis or another cause.
When to see a dentist or a doctor
Emergency: bleeding that will not stop, or bleeding with spreading facial swelling, difficulty breathing or swallowing, or high fever: call 112 in Türkiye (see the box at the top of this page).
Urgent dental appointment: very sore and swollen gums, teeth becoming loose or falling out, ulcers or red patches in your mouth, or a lump in your mouth or on your lip[1].
See a doctor: if your gums bleed and you also bleed or bruise easily elsewhere for no reason[5].
Routine dental appointment: gums that bleed when you brush or eat hard foods, painful or swollen gums, or bad breath[1].
Swollen, sore or itchy gums
Swollen and sore gums are, together with bleeding, the main symptoms of gum disease[1]. Very sore and swollen gums together with gum disease are a reason for an urgent appointment[1].
Itchy gums are a less specific complaint. At the examination the dentist looks first for plaque-related inflammation. Some gum conditions are not caused by plaque: they can be local reactions or signs of a general condition, and they usually do not settle after the plaque is removed[2]. That is one reason why gum symptoms that persist despite good cleaning need a closer look.
A lump or boil on the gum
A small, painful swelling on the gum, sometimes with pus, can be a periodontal abscess: an acute collection of pus in the gum pocket, with rapid tissue destruction and a risk of spreading[7]. An abscess can also start from an infected tooth. Either way it needs prompt dental care, and spreading swelling is an emergency (see the box at the top).
A lump in the mouth or on the lip that is not an obvious abscess also needs an urgent appointment[1].
White gums or white patches
A white patch in the mouth that does not go away should be checked by a dentist or GP. Leukoplakia patches are not usually painful, are irregular in shape, may be slightly raised and cannot be rubbed away; patches that can be wiped off may be oral thrush[6]. Leukoplakia carries a small chance of progressing to mouth cancer over time, which is why it must be checked[6].
At our clinic we do not take biopsies. When we see a white or red patch that needs further investigation, we refer you to a university faculty of dentistry.
Bleeding gums in pregnancy
Gum bleeding is common in pregnancy. A 2022 meta-analysis of 20 studies found bleeding on probing in 67% of pregnant women, with rates rising gradually through pregnancy; the studies varied widely[3]. The NHS advises regular dental check-ups especially when you are pregnant[1].
At our clinic, during pregnancy we only do urgent work, in the second trimester and approved by your physician, and we do not take dental X-rays; definitive treatment is postponed until after the birth. Careful brushing and daily cleaning between the teeth matter all the more during these months. More on pregnancy and medical conditions is in our guide to oral health and medical conditions.
Bleeding around implants and bridges
Healthy tissue around an implant does not bleed on gentle probing. Bleeding on gentle probing is the main sign of peri-implant mucositis, which is caused by plaque; peri-implantitis adds progressive bone loss around the implant[8]. Bleeding around an implant is therefore a reason to clean more carefully and have it checked, not to wait.
How to clean around implants and under bridges is shown in how to clean implants and bridges; the warning signs of a failing implant are covered in dental implant failure.

Frequently asked questions
Why do my gums bleed when I brush?
The most common reason is plaque-induced gingivitis: plaque left along the gum line irritates the gums, which become red, swollen and bleed easily. Brushing too hard can also make gums bleed. Gentle brushing twice a day and daily cleaning between the teeth usually help, but a dentist should check, because the same sign appears in periodontitis.
Should I stop flossing if my gums bleed?
No. Avoiding the area lets plaque build up, and plaque is what irritates the gums. Keep cleaning between your teeth gently every day with floss or interdental brushes, whichever fits. If the bleeding does not settle, or comes with pain, swelling or loose teeth, have your gums examined.
Are bleeding gums serious?
Usually they are a sign of gum inflammation that can be reversed, but they can also be a sign of periodontitis, which damages the bone around the teeth. Bleeding gums together with easy bruising elsewhere can point to a blood disorder and need a doctor. Bleeding that will not stop is a medical emergency.
Can a vitamin deficiency cause bleeding gums?
Low vitamin C intake can. A systematic review of 15 clinical trials found that vitamin C supplements reduced gum bleeding when blood vitamin C levels were low, but not clearly when levels were adequate. Plaque is still the most common cause, so see a dentist, and ask your doctor before taking supplements.
My gums bleed during pregnancy. What should I do?
Bleeding gums are common in pregnancy and tend to increase as it progresses. Keep brushing carefully with fluoride toothpaste and clean between your teeth every day, and tell your dentist and midwife or doctor. At our clinic we only do urgent, physician-approved work in the second trimester and take no dental X-rays during pregnancy.
My gums bleed around an implant. What does it mean?
Bleeding on gentle probing is the main sign of peri-implant mucositis, an inflammation of the gum around the implant caused by plaque. Caught early, it is managed with better cleaning and professional care. Left alone, it can progress to peri-implantitis with bone loss, so have the implant checked rather than waiting.
