Why Do My Gums Bleed When I Brush?
Bleeding gums when you brush or floss are not something you should regularly ignore. While occasional bleeding can happen if you’ve recently started flossing or are brushing too aggressively, frequent bleeding can be a sign of gum inflammation or gum disease.
What Causes Gums to Bleed?
One of the most common reasons gums bleed is plaque buildup along the gumline. Plaque contains bacteria that can irritate the gums, causing them to become red, swollen, tender, and more likely to bleed.
This early stage of gum disease is called gingivitis. The good news is that gingivitis can often be improved with consistent brushing, flossing, and professional dental cleanings.
However, bleeding gums can have other causes, including:
Brushing too hard
Not flossing regularly
Using a toothbrush with hard bristles
Gum disease that has progressed beyond gingivitis
Certain medications
Hormonal changes
Ill-fitting dental appliances or restorations
Other health conditions
If your gums bleed regularly, it's worth finding out what's causing it rather than simply avoiding the area.
Should I Keep Flossing If My Gums Bleed?
Yes, in most cases, you should continue gently cleaning between your teeth.
If you don't floss regularly, your gums may bleed when you first begin. As plaque and bacteria are removed more consistently, the inflammation can improve and the bleeding may decrease.
The key is to be gentle. Slide the floss between your teeth and curve it around each tooth rather than snapping it against your gums.
If you're flossing consistently and your gums continue to bleed, mention it to your dentist or hygienist.
How Can I Stop My Gums From Bleeding?
Improving your daily oral hygiene is an important first step.
Brush twice a day with a soft-bristled toothbrush and fluoride toothpaste. Use gentle pressure and spend about two minutes brushing.
Clean between your teeth daily with floss or another method recommended by your dental team. Brushing alone doesn't clean all of the surfaces between your teeth.
Keep up with professional cleanings and exams. A hygienist can remove hardened tartar that can't be removed with a toothbrush or floss at home and check your gums for signs of inflammation or disease.
If you have been told that you have gum disease, your dental team may recommend a different cleaning schedule or additional treatment based on your individual needs.
When Should I See a Dentist About Bleeding Gums?
If your gums bleed once after brushing particularly hard, it may not be a reason for concern. Regular or unexplained bleeding is different.
Schedule a dental appointment if you notice:
Gums that bleed frequently when brushing or flossing
Red, swollen, or tender gums
Gums pulling away from your teeth
Persistent bad breath
Loose or shifting teeth
Changes in the way your teeth fit together
Gum disease doesn't always cause noticeable pain, which is one reason regular dental exams are important.
