You’re brushing your teeth, and you notice a little pink in the sink. Or maybe you’re flossing, and the string comes out with a bit of red on it. It’s easy to shrug off. Maybe you brushed too hard. Maybe you flossed after a long break. It’s probably nothing, right?
Not always. Bleeding gums are one of the most common dental complaints we see at Ardmore Family & Cosmetic Dentistry, and they’re also one of the most ignored. Your gums shouldn’t bleed. If they do, they’re trying to tell you something. Let’s talk about what that message might be.

The Most Common Cause: Plaque Buildup
Nine times out of ten, bleeding gums come down to plaque. Plaque is a sticky film of bacteria that forms on your teeth throughout the day. When it sits along the gum line, your body’s immune system responds. The gums become inflamed. They get red, swollen, and tender. And when you brush or floss, they bleed.
This early stage is called gingivitis, and it is reversible. With better home care and a professional cleaning, your gums can heal completely.
But if plaque stays put long enough, it hardens into tartar. Tartar can’t be brushed away. It sits below the gum line, and inflammation worsens. That’s when gingivitis turns into periodontitis, the advanced form of gum disease. At that point, the damage becomes permanent. Gums pull away from teeth. Bone starts to dissolve. Teeth can loosen and even fall out.
That’s why you should pay attention to bleeding gums now, not later.
Other Reasons Your Gums Might Bleed
Plaque is the usual suspect, but not the only one. Other causes include:
- Brushing too aggressively: A soft-bristled brush and gentle pressure are all you need. Hard scrubbing irritates the gums.
- Flossing incorrectly: Snapping the floss down too hard can cut the gum tissue.
- Certain medications: Blood thinners and some other prescriptions make gums more prone to bleeding.
- Hormonal changes: Pregnancy, puberty, and menopause can all make gums more sensitive.
- Vitamin deficiencies: Low vitamin C or K levels can affect gum health.
- Medical conditions: Diabetes, bleeding disorders, and other health issues can contribute.
- Ill-fitting dental work: A crown or filling that doesn’t fit properly can trap plaque and irritate the gums.
When Should You Worry?
Occasional bleeding, especially if you just started flossing again, is usually not a big deal. It often stops within a week or two as your gums adjust.
But you should call us if:
- Your gums bleed every time you brush or floss
- The bleeding doesn’t stop after a few minutes
- Your gums are swollen, red, or tender
- You notice bad breath that won’t go away
- Your gums seem to be pulling away from your teeth
- Your teeth feel loose or have shifted
Those are signs that something more than a little irritation is going on.
What You Can Do at Home
Start with the basics. Brush twice a day for two minutes with a soft-bristled brush. Floss once a day, gently. Use a fluoride toothpaste and consider an antibacterial mouthwash.
Don’t stop flossing just because your gums bleed. That’s often a sign you need to floss more, not less. The bleeding usually stops once the plaque is gone and your gums have healed.
When to See Us
If you’ve improved your home care and the bleeding continues after two weeks, it’s time to see a professional. We can check for tartar buildup, measure your gum pockets, and determine whether gum disease is present.
Treating gum disease early is far easier, faster, and less expensive than treating it late. And in many cases, we can use gentle laser therapy to treat the gums comfortably, with minimal bleeding and faster healing.
Don’t Ignore the Signs
Bleeding gums are your body’s way of asking for help. Listen to it.
