No – healthy gums should not bleed regularly. Mild bleeding when first beginning to floss can happen, but ongoing bleeding is a sign of gum inflammation and should be checked.

Bleeding Gums? Why You Should Never Ignore Them
Have you noticed blood in the sink after brushing or flossing? Bleeding gums are one of the most common early warning signs of gum problems – yet many people brush them off as “no big deal.” At Puresmile Borehamwood Dental & Implants, we see patients from Borehamwood and across Hertfordshire who wish they had taken action sooner.
Bleeding gums aren’t just inconvenient – they’re usually a warning sign that something isn’t quite right. Here’s everything you need to know about what causes bleeding gums, what they could mean for your oral health, and how we treat them.
What Causes Bleeding Gums?
Bleeding gums are most often a sign of inflammation, which typically begins with plaque – a sticky film of bacteria that forms on your teeth and gums daily.
1. Gingivitis (Early Gum Disease)
The most common cause of bleeding gums is gingivitis, the earliest stage of gum disease. When plaque isn’t removed through regular brushing and cleaning between teeth, it irritates your gum tissue, leading to:
- Red, swollen gums
- Tenderness or soreness
- Bleeding during brushing or flossing
Good news: Gingivitis can be reversible with proper care and professional treatment.
2. Periodontitis (Advanced Gum Disease)
If gingivitis is left untreated, it can progress into periodontitis – a more serious form of gum disease that affects the bone supporting your teeth. Signs include:
- Persistent bleeding
- Gums recession
- Loose teeth
- Persistent bad breath
This stage requires professional dental treatment to manage and prevent further damage.
3. Incorrect Brushing or Flossing
Sometimes bleeding isn’t caused by disease at all – it’s caused by technique. You may be:
- Flossing after a long break
- Brushing too hard
- Using a hard-bristled toothbrush
Switching to a soft-bristled toothbrush and adopting a gentle brushing technique can help reduce irritation.
4. Hormonal Fluctuations
Hormonal changes – such as those during pregnancy, menopause or puberty – can make gums more sensitive and more prone to bleeding.
5. Medications and Medical Conditions
Certain medications (like blood thinners) and health conditions (such as diabetes) can increase the likelihood of gum bleeding. Always tell your dentist about any medications or conditions you have.
Why You Shouldn’t Ignore Bleeding Gums
Bleeding gums aren’t just a dental issue – they’re a sign of inflammation, and research shows that inflammation in the mouth may be linked to wider health concerns such as:
- Heart disease
- Diabetes complications
- Stroke
- Pregnancy complications
That’s why we encourage patients from Borehamwood and across Hertfordshire to take bleeding gums seriously and seek professional care early. Treating gum problems early often means simpler treatment and better outcomes.
What to Do If Your Gums Are Bleeding
1. Keep Brushing and Flossing
It might seem instinctive to avoid brushing an irritated area, but skipping oral hygiene allows plaque to build up. Instead:
- Brush twice a day with fluoride toothpaste
- Clean between your teeth daily with interdental brushes or floss
- Use a soft-bristled toothbrush
2. Consider an Antibacterial Mouthwash
If recommended by your dental professional, an antibacterial mouthwash can help reduce the bacteria that cause gum inflammation.
3. Book a Dental Hygiene Appointment
If your gums bleed regularly for more than a few days, it’s time to see a dentist. A professional assessment will help determine the cause and ensure you receive the right treatment.

Top 5 FAQs About Bleeding Gums
Is it normal for gums to bleed when I brush?
Can bleeding gums go away on their own?
Early gum inflammation may improve with better oral hygiene. However, once gum disease has progressed, professional treatment is necessary. Leaving it untreated usually worsens the condition.
Am I brushing too hard if my gums bleed?
Brushing too hard or using a hard-bristled toothbrush can irritate gums, but the most common cause of bleeding is plaque-related inflammation – not brushing force alone.
Are bleeding gums serious?
Bleeding gums are usually a warning sign of gum disease. If left untreated, gum disease can lead to bone loss, loose teeth, and may be linked to general health concerns. Early treatment improves outcomes.
When should I see a dentist about bleeding gums?
You should make an appointment if your gums:
- Bleed regularly
- Continue bleeding for more than a week
- Are swollen or tender
- Recede or pull away from teeth
- Are accompanied by bad breath or loose teeth
