Do you have bleeding gums? This could be an indication that you are suffering from gingivitis, a gum disease caused by plaque build-up around teeth and the gumline. Swelling or redness of the gums, receding gumline, and bad breath can be another sign of gingivitis. Consult with your dentist if you see any symptoms because if left untreated, gingivitis can lead to periodontal disease and even tooth loss. To help prevent gingivitis you should be sure to brush twice and floss once a day.
