Mythbusting Dental Myth

If your gums bleed when you floss, it's best to leave them alone.

The real deal: 
"The reason our gums bleed is due to inflammation," explains Ferraz-Dougherty. Often it happens when bacteria and plaque get stuck in between our teeth where toothbrush bristles don't reach properly. Over time the bacteria builds up and causes the gums to become inflamed. Bleeding is part of that process.If you floss once a month (or just before going to the dentist), it's likely you'll notice your gums bleeding. "That's a sign telling you something is going on there," says Ferraz-Dougherty. Make flossing a daily habit and the inflammation — and the bleeding — will go away with time.
