Blood coming from your mouth is definitely not normal and you should see a dentist
to be examined. The skin on your gums is thin and especially sensitive. Bleeding
when you are brushing can be a sign of gingivitis which is a condition where your gums are inflamed. Gingivitis is caused by poor oral hygiene. Poor oral hygiene leads to bacterial overgrowth which can cause inflammation. Inflammation then weaken the skin integrity, which increases the risk of bleeding. Routine oral hygiene should include brushing at least twice a day with good circular motion over each tooth. It should also include flossing between each tooth to minimize the amount of plaque buildup which can cause gingivitis. You can also use mouth wash. Again, you should make an appointment with a dentist to have your mouth examined. The dentist can guide in terms of how you can further take care of your teeth. You should also consider making an appointment with a primary care doctor
. They can also evaluate the bleeding in your mouth to determine if you need any further lab tests. Some patient have bleeding conditions such as having low platelets or disorders in clotting factors. These conditions could be investigated with basic lab tests. If you have any signs of bleeding in your stool, urine, vomit, you should go to the emergency room.
