Gum disease is a common condition in which gums become sore, infected and swollen. Common symptoms of a gum disease include bleeding and bad breadth. The early stage is known as gingivitis and if it isn't treated properly, it turns into a condition known as periodontists. This weakens the supporting teeth, damaging the bone in your jaw to open up a space between the gum and teeth. In severe cases your teeth become loose and fall out.
