Why Your Gums Bleed: Common Causes and When to See a Dentist
- Feb 4

Bleeding gums are a common concern, and often more than just a one-off annoyance. While occasional bleeding after brushing or flossing might not seem serious, persistent or unexplained bleeding can signal greater dental issues. Here's a detailed look at why your gums may bleed, how to manage it, and when it's time to book a dental appointment.
Common Causes of Bleeding Gums
1. Plaque Build-up and Poor Oral Hygiene
Plaque is a sticky film of bacteria, food particles, and saliva that builds up at the gumline if not removed. This leads to irritation, inflammation, and bleeding, which are classic signs of gingivitis and precursors to more serious gum disease.
2. Gingivitis and Periodontitis
Gingivitis is an early, reversible form of gum disease where gums become red, swollen and bleed easily. If left untreated, it can evolve into periodontitis, a more severe condition causing gum recession, bone loss, and potentially tooth loss.
3. Brushing or Flossing Too Aggressively
Using a hard-bristled toothbrush or brushing too forcefully can damage your gum tissue, especially if you're not used to more vigorous cleaning. Using a softer approach helps prevent irritation.
4. Inconsistent Flossing
If you’ve neglected flossing and suddenly restart, you may notice bleeding. It's a sign that plaque between teeth is now being disrupted under the surface.
5. Hormonal Fluctuations
Changes during puberty, pregnancy, menstruation, or menopause can make gums more reactive. Increased blood flow heightens sensitivity, so gums may bleed more readily.
6. Vitamin Deficiencies
Lack of vitamins C or K weakens gum tissue and impairs healing, increasing bleeding susceptibility.
7. Certain Medications
Blood-thinners (like warfarin or aspirin), chemotherapy drugs, and antibiotics affecting platelet function can result in easier gum bleeding.
How to Manage Bleeding Gums at Home
You can manage bleeding gums at home with the following advice:
Swish with warm salt water (½ tsp salt in 250 mL warm water) to soothe and cleanse irritated gums.
Switch to a soft-bristled toothbrush and use gentle, circular strokes.
Floss daily, even if it bleeds, to remove plaque and encourage healing.
Rinse with an antibacterial or alcohol-free mouthwash to reduce bacteria.
Maintain excellent oral hygiene: brush twice daily, floss daily, and attend regular dental check-ups.
When to See a Dentist
Not all gum bleeding is harmless. You should consider seeing your dentist if:
Bleeding persists for more than 7 to 10 days despite improved hygiene.
You notice signs of gum recession, deepened pockets, loose teeth, or pus.
You experience persistent bad breath or discomfort when chewing.
Bleeding accompanies other health concerns like anxiety, fatigue, unexplained bruising, or is triggered after systemic illness or medication changes.
You have personal risk factors like diabetes, tobacco use, or a compromised immune system.
Early intervention prevents further deterioration. Your dentist may recommend professional cleaning, scaling and root planing, antibiotics, or, in advanced cases, periodontal surgery.
Prevention Is Better Than Cure
Prioritise consistent brushing twice daily and flossing daily.
Choose a soft-bristled brush and gentle technique.
Visit your dentist for routine cleanings and periodontal screenings.
Maintain a balanced diet rich in vitamins C and K; think leafy greens, citrus fruits, and legumes.
Quit smoking and take care when handling dental appliances.
