How do I know if I have Gingivitis?

Classic signs and symptoms of gingivitis include red, swollen, tender gums that may bleed when you brush. Another sign of gum disease is gums that have receded or pulled away from your teeth, giving you teeth an elongated appearance. Gum disease can cause pockets to form between teeth and gums, where plaque and food debris collect. Some people may experience recurring bad breath or a bad taste in their mouth, even if the disease is not advanced.
