Why Do My Gums Bleed?
Last updated: 2026-06-25
Bleeding gums are one of the most common dental complaints — and in most cases they're an early, reversible warning sign rather than something serious. Here's what causes it, when to worry, and how to stop it.
Why are my gums bleeding?
The usual cause is plaque: a sticky film of bacteria that collects where the gum meets the tooth. If it isn't cleaned away daily, it irritates the gum, which becomes inflamed and bleeds easily — this early stage is called gingivitis. Common contributing factors include:
- Inconsistent cleaning — especially skipping flossing or interdental brushes, where plaque hides.
- Brushing too hard or a stiff-bristled brush, which irritates the gum margin.
- Smoking, which both worsens gum disease and can mask the bleeding.
- Hormonal changes in pregnancy or menopause, which make gums more sensitive.
- Some medications (such as blood thinners) and health conditions like diabetes.
Is bleeding when I brush serious?
Occasional bleeding when you start a better flossing routine is common and usually settles within a week or two as the gums get healthier. It's worth seeing a dentist if the bleeding:
- Lasts longer than two weeks despite good cleaning
- Comes with swollen, tender or receding gums
- Is joined by persistent bad breath, loose teeth or a change in your bite
These can signal that gingivitis is progressing to periodontitis, which needs professional treatment to stop it advancing.
How do I stop my gums bleeding?
- Clean between your teeth daily. Floss or interdental brushes remove the plaque at the gum line that causes most bleeding.
- Brush gently, twice a day. Use a soft brush angled toward the gum line for two minutes — firmer isn't better.
- Don't stop because it bleeds. Gentle, consistent cleaning is what calms the gums; bleeding usually reduces within days.
- See a hygienist. A professional scale and polish removes hardened tartar that brushing can't.
Daily Care Protocol with Dental Pro 7
As a finishing step, a lipid-based concentrate can support the gum line where water-based rinses wash away.
- Step 1. Apply a few drops of Dental Pro 7 to your toothbrush.
- Step 2. Brush gently along the gum line for two minutes.
- Step 3. Leave it on rather than rinsing, so it stays in contact with the gums.

Frequently Asked Questions
Why do my gums bleed when I brush my teeth?
Usually because plaque at the gum line has inflamed the gums (gingivitis), making them bleed when disturbed. Cleaning between the teeth daily and brushing gently along the gum line normally resolves it within a week or two.
Should I stop brushing or flossing if my gums bleed?
No — that makes it worse. Gentle, consistent cleaning is what reduces the inflammation causing the bleeding. If it hasn't improved in two weeks, see a dentist.
Can bleeding gums be a sign of something serious?
Persistent bleeding can indicate periodontitis (advanced gum disease) and, less commonly, issues like a vitamin deficiency or a side effect of medication. If it lasts beyond two weeks or comes with swelling, receding gums or loose teeth, get it checked.
What can I use at home for bleeding gums?
Daily flossing or interdental brushing, gentle brushing with a soft brush, and consistency are the foundation. A lipid-based gum concentrate like Dental Pro 7 can be used as a finishing step to support the appearance of firmer, healthier-looking gums between dental visits — alongside, not instead of, professional care.
