Hi i would like to find out when i clean my nose or guggle my mouth i find a little blood my gums are 100% healthy what can the problem be also get headaches?

Bleeding gums: It's not unusual to find someone who although they generally have healthy gums, do have one or two areas where perhaps the gums are irritated or slightly inflamed, which in turn results in some gingival bleeding. It doesn't take much blood which when mixed with saliva looks worse. However, do get checked out by your own dentist just to be sure it's nothing more. Brush and FLOSS regularly as well.
