What to do if i have red bleeding gums,bad breath,blood in spit what is it?

Find a DDS: Although there are possible medical reasons, it would be important to be sure you are following a home care regimen that includes proper brushing and flossing. You should seek the help of a dentist so that any hardened plaque (called calculus) can be removed. The calculus will continue to irritate your gum tissue and can only be removed professionally by a dentist or hygienist.

Gingivitis: and/or periodontitis. See your dentist immediately for a cleaning and removal of all plaque, often formed by moth bacteria.

Red bleeding gums: You have infected gums. Get to a dentist ASAP. If this is not treated it will get worse, leading to loss of teeth and possible systemic infection.
