Gum disease is where your gums are red and swollen.
Gum disease is caused by a build-up of a sticky substance called plaque on your teeth. This can happen if you do not brush your teeth regularly.
Brushing your teeth twice a day and flossing regularly can help gum disease. A dental hygienist may need to thoroughly clean your teeth.
Symptoms of gum disease include bleeding gums, swollen gums and bad breath.
