The only thing I can thinkis that it can be a gum infection or something. You should really get an appt with the dentist to find out.

You probably having gum inflammation or problem with your perio. You should make an app with a dentist and more likely you will need to get peridex to rinse your mouth with

Do you brush on a regular basis? I know sometimes I miss a session or two and the next time a vigorously brush they bleed like crazy. Keep up and never miss a brushing they should grow tough and stop bleeding. If they do bleed and it hurts try using flouride and floss. Might be an infection, but brush through it. I know it hurts, but brush on and your gums should harden up. Just my experience.

You probably have gum disease. Sounds gross doesn't it. I was shocked to find out I had it about a year ago. I don't even have a cavity, how in heck am I going to get gum disease? You can get it from not flossing, which I neglected to do. Make sure you go see your dentist.

Bleeding gums can also be a sign of vitamin deficiencies.

Sounds like you have gingivitis, you need to see a dentist pronto. They may have to cut some of the gums away. That happened to me many years ago. Good luck
