Gums that bleed can be a sign of gingivitis or periodontitis. Gingivitis is infection, inflammation, or swelling of the gums. It is one of the most common gum problems. Early gingivitis can be painless and may not be noticed.
Symptoms can include red, soft, or swollen gums, bad breath, and an unpleasant taste in the mouth.
Pregnant women and untreated diabetics are especially prone to developing gingivitis. Bleeding gums can also be a sign of periodontitis. This is a disease of the gum tissue caused by plaque that has hardened on your teeth. When this happens it will be necessary for a dental hygienist or a dentist to scrape this material off your teeth. Periodontitis can lead to infected gums that pull away from the normal gum line.
