The most common cause of bleeding gums is gum inflammation (gingivitis) caused by plaque and tartar build-up. Brushing too hard, hormonal changes in pregnancy and blood-thinning medicines can also increase bleeding. Instead of stopping brushing, keep cleaning gently but regularly. If bleeding does not lessen within 1–2 weeks, happens on its own or comes with swelling, see a dentist.
Why do gums bleed?
Bleeding gums usually show that the gums are inflamed. The most common cause is bacterial plaque collecting along the gum line and the tartar that forms when this plaque hardens.
Bacteria in plaque cause inflammation in the gums. Inflamed gums turn red, swell and bleed even with light contact such as brushing or flossing. We explain how tartar forms on our page what is tartar.
Other common causes include:
- A hard brush or the wrong technique: Pressing too hard or brushing with sideways strokes irritates the gums.
- Starting to floss: There may be slight bleeding in the first days; it usually lessens with regular use.
- Hormonal changes: Pregnancy, puberty and periods can increase the gums' reaction to plaque.
- Medicines: Blood thinners can make bleeding easier; some medicines can cause gum overgrowth.
- Poorly fitting filling, crown or denture margins: These make it easier for plaque to cling on.
- General health: Uncontrolled diabetes increases the risk of gum disease. Rarely, blood disorders or vitamin deficiency can also show up as bleeding.
The link between bleeding gums and tartar
Tartar is one of the main causes of bleeding gums. Its rough surface makes it easier for new plaque to cling on and keeps the gums constantly inflamed.
Tartar cannot be brushed off. So while tartar is present, bleeding may not stop completely no matter how carefully you brush. Build-up below the gum is often dark and cannot be seen; this is explained in detail on our page black tartar.
A scale and polish at the clinic removes the source of the inflammation. There may be slight bleeding for the first 1–2 days after cleaning. As the gums heal, bleeding usually decreases noticeably within a few days to a few weeks.
Gingivitis and periodontitis: what stage does bleeding indicate?
Bleeding gums can occur in both early and advanced gum disease. An examination is needed to determine the stage.
| Feature | Gingivitis (gum inflammation) | Periodontitis |
|---|---|---|
| Tissue affected | Gums only | Gums, the connective tissue holding the tooth, and bone |
| Common signs | Redness, swelling, bleeding when brushing | Bleeding, gum recession, deep pockets, bad breath, loose teeth |
| Reversibility | Usually reversible with cleaning and good care | Bone loss usually does not come back; the aim is to stop it progressing |
| Treatment | Scale and polish, oral hygiene instruction | In addition to cleaning, root planing (curettage) and regular follow-up |
In smokers, the gums may bleed less because blood vessels can narrow. This does not mean the disease is milder; it can hide the signs.
When are bleeding gums serious?
Slight bleeding now and then when brushing is often an early sign of gum inflammation. However, some situations should be assessed without waiting.
Have an examination if bleeding does not lessen within 1–2 weeks despite careful care; if it happens on its own, regardless of brushing; if there is swelling, pain or discharge from the gums; or if you notice loose teeth or gum recession.
If you take blood-thinning medication and bleeding lasts a long time, talk to both your dentist and the doctor who manages your medication. Do not stop your medicine or change the dose on your own.
If bleeding gums come with nosebleeds, easy bruising of the skin, unexplained tiredness or weakness, you are also advised to see your GP. These signs usually do not point to anything serious, but it is important to look into the cause.
What should you do when your gums bleed?
When your gums bleed, do not stop brushing; on the contrary, keep cleaning away plaque gently but regularly. Brushing less out of fear of bleeding increases plaque and prolongs the inflammation.
- Use a soft brush: Brush twice a day for about 2 minutes, with the brush angled slightly towards the gum line and using small movements.
- Clean between your teeth: Use dental floss or a suitably sized interdental brush every day; slight bleeding in the first days usually lessens.
- Choose fluoride toothpaste: Avoid highly abrasive powders and scraping tools.
- Cut down on or quit smoking: Smoking slows gum healing.
- Do not rely on mouthwash alone: Antiseptic mouthwashes can give short-term support, but they should not be used for long periods without a dentist's advice, and they do not remove tartar.
- Have an examination: If there is tartar, bleeding usually does not stop completely until it is removed.
Bleeding gums in pregnancy
Bleeding gums are common in pregnancy. Hormonal changes increase the gums' reaction to plaque; this is called pregnancy gingivitis.
Symptoms usually become more noticeable in the second trimester and may lessen after birth. Even so, it is important not to neglect oral care during this time.
- If nausea makes brushing difficult, try a brush with a small head and a little toothpaste.
- After vomiting, rinse your mouth with water instead of brushing straight away.
- Tartar removal can usually be done during pregnancy; the timing is decided at the examination, together with the doctor monitoring your pregnancy.
- If you notice a fast-growing swelling on the gum that bleeds easily, show it to your dentist.
Bleeding gums and bad breath
Bleeding gums and bad breath often come from the same source: plaque, tartar and gum pockets. Bacteria in these areas produce foul-smelling compounds.
With bleeding gums you may also notice a metallic taste in your mouth. As the gums heal, both bleeding and odour usually decrease. For other possible causes of the smell, see our page bad breath.
What happens at the examination?
The examination determines the cause of the bleeding and the stage of any gum disease. Treatment is planned based on these findings.
- The gums are examined and, if needed, gum pocket depth is measured.
- X-rays may be taken to see the condition of the bone.
- You are asked about the medicines you take, pregnancy and your general health.
- If there is tartar, cleaning is planned; deep pockets may need additional treatment.
- Brushing technique and cleaning between the teeth are explained to suit you.

Frequently asked questions
Do bleeding gums stop on their own?
Slight bleeding caused by brushing too hard or starting to floss may lessen within a few days. Bleeding caused by tartar, however, usually does not stop completely until it is cleaned.
Should I stop brushing if my gums bleed?
No. Stopping brushing increases plaque and prolongs the inflammation. Keep brushing gently with a soft brush and cleaning between your teeth.
Which department should I go to for bleeding gums?
You can see a general dentist first. If gum disease has progressed, treatment is usually planned within periodontology (the field of gum disease).
Is gum bleeding normal after tartar removal?
There may be slight bleeding for the first 1–2 days, especially if the gums are inflamed. If bleeding lasts longer than a week or there is swelling, you are advised to contact the clinic.
Does gum bleeding break the fast or ablution?
According to statements by Diyanet (Turkey's Presidency of Religious Affairs), there are differing views on this among the schools of Islamic law. For details, see our page dental treatment, fasting and ablution.
