When your gums bleed, that means they are more fragile than normal. You must change the way you’re taking care of them, so that the situation doesn’t get worse.
Your gums become fragile when they’re invaded by bacteria—infecting them and causing inflammation and swelling (which you might not be able to feel). But the swelling makes them fragile and when you brush your teeth, they may bleed.
Bacteria invades your gums from its “home base:” the plaque that builds up on your teeth over time.
To prevent the bacteria from advancing from your gums to the bone that supports your teeth, you have to control the bacteria and remove its home base.
The good news is, with timely treatment, your gums can be restored to a normal healthy state and you can look forward to chewing, eating and brushing your teeth without your gums bleeding.
