Why do my gums bleed when I brush?
Healthy gums do not bleed when cleaned. Bleeding is the earliest reliable sign of gum inflammation, driven by bacterial plaque and hardened calculus at and below the gum margin. At the gingivitis stage it is fully reversible. Once the inflammation has destroyed attachment and bone, it is periodontitis — still treatable, but the lost bone does not grow back on its own, which is why bleeding is worth acting on early.
What bleeding gums usually turns out to be
- Gingivitis from plaque and calculus at the gum margin
- Periodontitis with pockets and bone loss
- Incorrect or aggressive brushing technique
- Hormonal change in pregnancy, or poorly controlled diabetes
- Smoking or tobacco use, which masks bleeding while worsening the disease
- Medication side effects and, rarely, blood disorders
What to do before you are seen
- Keep cleaning the area gently — stopping makes the inflammation worse
- Clean between the teeth daily; a brush alone reaches only three of five surfaces
- Book a scaling and a periodontal assessment with pocket charting
- Report any medication or medical condition that affects bleeding
This is general guidance and does not replace an examination. Only a clinical examination with radiographs can identify which tooth or tissue is causing your symptom.
When to see us
- Gums that bleed without provocation, or bleeding that has become heavier
- Teeth that feel loose, are drifting, or gaps that are opening up
- Persistent bad breath or taste, gum abscesses, or pus on pressing the gum

Bleeding Gums and Gum Disease: A Complete Guide
What bleeding gums usually mean, how gingivitis progresses into periodontal disease, and the treatment path from scaling to gum surgery.
Gum Disease: Detection and Treatment
From reversible gingivitis to periodontitis, the warning signs, staged treatment and the link to overall health.
Chronic Bad Breath Caused by Gum Infection
Chronic bad breath, or halitosis, is frequently driven by underlying gum disease. Subgingival bacteria produce volatile sulphur compounds within periodontal pockets. Effective resolution requires professional periodontal debridement, targeted biofilm disruption, and meticulous daily interdental hygiene rather than cosmetic masking.
Laser Assisted Periodontal Therapy Explained
Laser therapy offers a precise, minimally invasive way to treat gum disease. We use advanced lasers to target bacteria, reduce pockets, and stimulate healthy tissue growth.
Bleeding Gums When Brushing or Flossing Daily
Bleeding gums when brushing or flossing indicates underlying gingival inflammation, most commonly driven by microbial dental plaque. If neglected, reversible gingivitis can progress to irreversible periodontitis, necessitating prompt clinical assessment, professional debridement, and meticulous daily interdental hygiene.
Scaling and Root Planing Deep Cleaning Procedure
Scaling and root planing is a non-surgical deep cleaning procedure designed to treat chronic periodontitis. It removes subgingival plaque biofilm, hard calculus, and bacterial endotoxins from tooth root surfaces to arrest active gum disease and prevent bone loss.
Treating Bleeding Pregnancy Gingivitis and Swollen Gums
Pregnancy gingivitis is a hormone-mediated inflammatory condition of the gums triggered by plaque. Timely professional scaling, gentle home plaque control, and second-trimester maintenance resolve bleeding, prevent periodontal breakdown, and protect maternal and foetal health safely.
Gum Disease and Heart Health
Explore the critical link between chronic gum inflammation and heart health, and how maintaining periodontal hygiene can protect your cardiovascular system from systemic bacterial complications.
What Causes a Dark Line Around a Crown
A dark line around a dental crown typically arises from exposed metal collars in porcelain-fused-to-metal restorations, gingival recession, marginal microleakage, or recurrent tooth decay. Accurate diagnosis requires clinical probing, radiography, and determining whether structural replacement or periodontal intervention is indicated.
Maintenance Therapy After Gum Treatment
Periodontal maintenance is the secret to lasting gum health after treatment. We explain why frequent visits are essential to prevent the return of gum disease.
Full Mouth Disinfection for Healthy Gums
Full mouth disinfection is an intensive approach to treating severe periodontitis. We remove bacteria from all pockets to help your gums recover and halt disease progression.
Understanding the Causes of Bleeding Gums
Bleeding gums are a common symptom of gum disease and other oral health issues. Understanding the underlying cause is the first step toward effective treatment and healthy gums.
