Why Do My Gums Bleed When I Brush or Floss?

Bleeding gums are one of the most common concerns we hear from patients at Family Focus Dental and it’s something that should never be ignored.

Many people assume bleeding is normal, especially when flossing, but in reality healthy gums do not bleed. Bleeding is often your body’s way of telling you that your gums need attention.

What Does Bleeding Gums Mean?

In most cases, bleeding gums are an early sign of gingivitis, which is inflammation of the gums caused by plaque build-up.

Plaque is a sticky film of bacteria that forms on teeth every day. When it isn’t removed thoroughly, it collects along the gumline and triggers irritation, redness, swelling, and bleeding.

The good news? Gingivitis is completely reversible when treated early.

 

Common Causes of Bleeding Gums

1. Inadequate Brushing or Flossing

If brushing or flossing is inconsistent, plaque builds up quickly. Ironically, some patients stop flossing because their gums bleed — but this allows more bacteria to accumulate, making the problem worse.

With gentle, consistent cleaning, gums usually stop bleeding within 1–2 weeks.

2. Plaque and Tartar Build-Up

When plaque hardens, it turns into tartar, which cannot be removed at home. Tartar irritates the gums and causes ongoing inflammation and bleeding.

A professional clean at Family Focus Dental removes this build-up and allows your gums to heal.

3. Smoking or Vaping

Smoking and vaping reduce blood flow to the gums and impair healing. While some smokers may notice less bleeding, the damage is often more advanced — making gum disease harder to detect and treat.

4. Hormonal Changes or Medical Factors

Hormonal changes (such as pregnancy), certain medications, and medical conditions like diabetes can also make gums more sensitive and prone to bleeding.

 

Should You Be Concerned about Bleeding Gums?

If gingivitis is left untreated, it can progress to periodontitis, a more serious form of gum disease that can lead to:

  • Gum recession

  • Bone loss around teeth

  • Loose teeth

  • Tooth loss

At this stage, treatment becomes more complex, which is why early intervention is so important.

 

How to Stop Your Gums from Bleeding

Here’s what we recommend to our patients at Family Focus Dental:

  • Brush twice daily with a soft-bristled toothbrush

  • Use gentle circular motions along the gumline

  • Clean between your teeth daily with floss or interdental brushes

  • Avoid aggressive brushing

  • Attend regular dental check-ups and professional cleans

If bleeding persists beyond two weeks, it’s important to book an appointment.
