Bleeding gums: what they're telling you and how to stop them
Written with input from the clinical team at Smile Perfections in Oadby, led by principal dentists Dr Juttes Pallipatt (GDC 104499) and Dr Pratima Pallipatt (GDC 101258), with our dental hygienist and therapist Miss Jeromini Desmanramesh (GDC 297312).
You spit after brushing and there it is again: a streak of pink in the sink. It doesn’t hurt, so it’s easy to shrug off. Maybe you brushed a bit hard. Maybe it’s a new toothbrush. It’ll probably stop.
Sometimes it does. But bleeding gums are one of the most common early warning signs we see, and they’re rarely “nothing”. Healthy gums don’t bleed when you brush or floss. When they do, it’s usually your body telling you there’s inflammation that needs attention.
The good news is that, caught early, the cause is almost always reversible. This guide explains why gums bleed, how to tell how serious it is, and what actually stops it.
At Smile Perfections in Oadby, bleeding gums are one of the things patients mention most at their appointments, so this is the advice we give them every week.
Why do gums bleed?
In most cases, bleeding gums are caused by plaque, the soft, sticky film of bacteria that builds up on your teeth every day. When plaque sits along the gumline, the gums react to the bacteria by becoming inflamed. Inflamed gums are swollen, tender and full of extra blood vessels, so they bleed easily when touched by a toothbrush or floss.
This early stage is called gingivitis. It’s very common, and most adults will have it at some point. The important thing is that gingivitis can be completely reversed with better cleaning and a professional clean.
If plaque isn’t removed, it hardens into tartar, which you can’t brush away. The inflammation continues and can spread deeper, damaging the bone and tissue that hold your teeth in place. That’s when gum disease becomes much harder to treat.
How serious is your bleeding?
This is a rough guide to what different patterns of bleeding usually mean. It isn’t a diagnosis, but it can help you judge how soon to get checked.

Bleeding gums when brushing most days |
Gingivitis |
Improve your routine and book a hygiene appointment |
|
Bleeding with red, puffy or tender gums |
More established gingivitis |
See a hygienist soon |
|
Bleeding with bad breath or a bad taste |
Gum inflammation, possibly gum disease |

Loose or moving teeth |
More advanced gum disease |
Book a check-up as soon as possible |
|
Bleeding without brushing, unexplained bruising, or feeling unwell |
Possibly a medical cause |
Speak to your GP as well as your dentist |
Gingivitis or gum disease? Knowing the difference
People often use the terms interchangeably, but there’s an important difference between the early and later stages.
|
Gingivitis |
Periodontitis (advanced gum disease) |
|
|---|---|---|
|
What’s affected |
The gums only |
The gums, the bone and the fibres holding teeth in place |
|
Common signs |
Bleeding, redness, mild swelling |
Bleeding, bad breath, receding gums, loose teeth, gaps |
|
Pain |
Usually none |
Often painless until late on |
|
Can it be reversed? |
Yes, completely |
Damage to bone can’t be fully reversed, but it can be stopped and managed |
|
Treatment |
Better cleaning and a professional clean |
Deep cleaning, regular maintenance and sometimes specialist care |
One thing worth knowing: gum disease is often painless, even when it’s quite advanced. Many people only find out they have it when a dentist measures the gum pockets or sees bone loss on an X-ray. Our article on bone loss in teeth explains how this happens.
Other reasons gums might bleed
Plaque is the most common cause, but it isn’t the only one.
- A new or hard toothbrush, or brushing too hard. Switch to a soft or medium brush and use gentle circles
- Starting to floss. Gums often bleed for the first week or two, then settle as they get healthier
- Pregnancy. Hormonal changes make gums more sensitive to plaque, so “pregnancy gingivitis” is very common
- Hormonal changes around puberty, periods and the menopause
- Some medicines, including blood thinners, which can make bleeding more noticeable
- Diabetes, which makes gum disease more likely and harder to control
- Vitamin deficiencies, which are rare but can affect the gums
- Ill-fitting dentures, braces or retainers rubbing the gums
If your gums bleed without any obvious reason, you notice unexplained bruising, or you feel generally unwell, see your GP. Although uncommon, some blood conditions can show up in the gums first.
A word about smoking
Smoking reduces blood flow to the gums, so smokers often bleed less, even when they have gum disease. That can hide the problem until it’s quite advanced. If you smoke, regular check-ups are especially important, and stopping smoking is one of the best things you can do for your gums.
Should you stop brushing if your gums bleed?
No. This is one of the most common mistakes people make. It feels natural to avoid an area that bleeds, but leaving plaque there makes the inflammation worse.
Keep brushing and cleaning between your teeth gently but thoroughly. As the plaque is removed, the inflammation calms down and the bleeding usually reduces within one to two weeks.
A two-week reset for bleeding gums
If your gums bleed when you brush, try this for two weeks. It’s often enough to make a noticeable difference.
Every morning and night:
- Brush for two minutes with a fluoride toothpaste, using a soft or medium brush
- Angle the bristles towards the gumline and use small, gentle circles, not hard scrubbing
- An electric toothbrush with a pressure sensor can make this easier
- Spit, don’t rinse, after brushing
Once a day:
- Clean between every tooth with interdental brushes or floss. Interdental brushes are often easier and more effective where the gaps allow
Throughout the day:
- Cut back on sugary snacks and drinks
- Drink plenty of water
- If you smoke, try to cut down or stop
If the bleeding hasn’t improved after two weeks, or your gums are swollen, receding or sore, it’s time for a professional assessment.
What a hygienist does for bleeding gums
Home care is essential, but it can’t remove tartar or clean below the gumline where the bacteria causing gum disease live. That’s where a dental hygienist comes in.
At a hygiene appointment at Smile Perfections, our hygienist will:
- Check your gums for bleeding, swelling and pocketing
- Remove plaque and tartar from above and below the gumline
- Polish your teeth to make it harder for plaque to stick
- Show you exactly where you’re missing when you brush and clean between your teeth
- Recommend the right brush sizes and products for your mouth
- Suggest how often you should come back, depending on your gum health
If you’re nervous about a clean because your gums are sore, let us know. Our team is Dental Phobia Certified, and we’ll go at your pace. Our guide on how to clean calculus from teeth explains why professional cleaning matters so much.
Why check-ups matter, even if nothing hurts
At a dental check-up, your dentist doesn’t just look at your teeth. They also measure the depth of the small pockets between your teeth and gums. Healthy pockets are shallow; deeper pockets are a sign of gum disease. X-rays can show whether any bone has been lost.
This is how gum disease is picked up early, often before you notice anything yourself. If your dentist spots signs of gum disease, they’ll explain what they’ve found and put together a plan, which usually starts with a course of hygiene treatment.
Keeping up with regular dental check-ups means any changes in your gums are spotted and treated while they’re still small.
How often you need a check-up depends on your risk. Our article on how often you should go to the dentist explains why the answer is different for everyone.
What happens if bleeding gums are ignored?
Left untreated, gingivitis can progress to periodontitis. Over time, this can lead to:
- Gums pulling back from the teeth, making them look longer
- Persistent bad breath and a bad taste
- Sensitivity as tooth roots become exposed
- Teeth becoming loose or moving, sometimes opening up gaps. Our guide to a wobbly tooth covers this in more detail
- Eventually, losing teeth
There’s also growing evidence that gum disease is linked to wider health conditions, including diabetes and heart disease. Looking after your gums is good for your whole body, not just your mouth.
Once your gums are healthy: tidying up your smile
When inflamed gums heal, they tighten up around the teeth. For most people that’s simply a healthier-looking smile. But if gum disease has caused some recession, you may notice small dark triangles between your front teeth or slightly longer-looking teeth.
In many cases, composite bonding can be used to reshape the teeth and close those small gaps, without drilling healthy tooth. It’s important that the gums are healthy and stable first, so bonding is always a step that comes after gum treatment, never before.
Our page on composite bonding in Leicester explains how the treatment works and what’s involved.

Patients frequently ask
No. Healthy gums shouldn’t bleed when you brush or floss. Occasional bleeding after flossing for the first time, or after using a new brush, can happen, but regular bleeding gums when brushing usually mean inflammation caused by plaque.
With better brushing and daily cleaning between your teeth, mild bleeding often improves within one to two weeks. If it doesn’t, or your gums are swollen or receding, a professional clean and check-up are recommended.
Yes, if it’s gingivitis. Early gum inflammation can be completely reversed with good home care and professional cleaning. More advanced gum disease can’t be fully reversed, but it can be stopped and kept under control with regular treatment.
Mouthwash can help as part of a routine, but it won’t remove plaque or tartar on its own. Brushing, cleaning between your teeth and regular hygiene visits are far more important. Your hygienist can recommend a suitable mouthwash if needed.
If your gums still bleed after two weeks of good brushing and cleaning, or you notice swelling, receding gums, bad breath or loose teeth, book a check-up. See your GP as well if you have unexplained bruising or bleeding elsewhere.
If you’ve got a mouth ulcer that’s lasting longer than expected, or you’re getting them more often than feels normal, get in touch. We’ll take a proper look.
