Perio disease : Usually brushing when bleeding occurs in a sign of gingivitis leading to more severe periodontal disease. If you have a had recent dental work the crown, filling can possible not be contoured properly and cause irritation of gums.

Mouth bleeding: Generally bleeding from brushing comes from inflamed or irritated gums. You could have periodontial issues and should consult your dentist right away.

Continue brushing: As long as you are using soft bristle or ultrasoft brush, continue to brush parallel to the gum. This should stop the once a week bleeding which is a sign of only gingivitis. If persistent bleeding in several days or weeks, check with your dentist since you may have severe perio or other dental problems that must be evaluated and treated asap.
