Why Do My Gums Bleed? (And What Your Mouth Is Trying to Tell You)

You’re brushing your teeth before bed, you spit, and there it is: a little pink in the sink. If you’ve ever seen blood when you brush or floss, your first thought might have been, “I brushed too hard.” And maybe you did. But more often than not, bleeding gums are your mouth’s way of waving a small flag, asking for a little attention.

At Hermitage Dental in Edmonton, we see this question every single week. The good news? Bleeding gums are usually treatable. The better news? With the right care, you can often stop the bleeding in just a few weeks.

What Causes Bleeding Gums? in Edmonton, AB

The Most Common Cause: Gingivitis

The number one reason gums bleed is something called gingivitis. It sounds serious, but it’s actually the earliest stage of gum disease. Here’s how it works:

Your mouth is home to millions of bacteria. When plaque, that sticky, colorless film, builds up along your gumline, the bacteria irritate your gums. In response, your gums become inflamed, tender, and prone to bleeding. It’s your body’s way of saying, “Hey, clean this area better!”

The tricky part? Gingivitis often doesn’t hurt. You might not notice a thing except for that telltale pink when you spit. That’s why regular dental checkups are so important. We can spot inflammation early, often before you even notice it yourself.

Other Reasons Your Gums Might Bleed

While gingivitis is the usual suspect, there are a few other reasons your gums could be bleeding:

  • Flossing too aggressively (or not enough): If you’ve recently started flossing after a long break, bleeding is normal for a few days. But if you’re snapping floss into your gums like a rubber band, you can cause irritation. Gentle, consistent flossing is the key.
  • New or ill-fitting dental work: Crowns, bridges, or dentures that don’t fit properly can rub and irritate the gum tissue.
  • Certain medications: Blood thinners, some blood pressure medications, and even aspirin can make your gums more prone to bleeding.
  • Pregnancy: Hormonal changes during pregnancy can make gums more sensitive and inflamed, a condition often called “pregnancy gingivitis.”
  • Smoking: Here’s a surprising twist: smoking actually reduces bleeding by constricting blood vessels. But that’s not a good thing. It masks the problem, allowing gum disease to progress silently underneath.
  • Underlying health conditions: In some cases, bleeding gums can be linked to diabetes, vitamin deficiencies (like vitamin C or K), or other systemic issues.

What You Can Do at Home

The good news is that in most cases, you can turn things around with some simple changes:

  1. Brush gently but thoroughly. Use a soft-bristled toothbrush and angle it toward the gumline. Hard bristles won’t clean better; they’ll just irritate.
  2. Floss daily, and do it gently. Curve the floss into a C-shape around each tooth and slide it up and down. Don’t snap it into your gums.
  3. Try a saltwater rinse. A warm water and salt rinse can help soothe inflamed gums.
  4. Keep up with your regular cleanings. Professional cleanings remove the plaque and tartar you can’t get at home.
