What will make your teeth bleed after you brush them ?
Inflammation of the gums or gingivitis is a reason for bleeding gums because of an inadequate removal of plaque at the juncture between the teeth and gums. If plaque is not removed, it can harden to form tartar. This can lead to gum disease, and can affect the gums and the jawbone. Other reasons gums can bleed include: brushing too hard, deficiency of vitamin C (scurvy) or vitamin K, hormonal changes, improper flossing, ill-fitting oral appliance(denture), bleeding disorders. Leukemia can be a cause of bleeding gums and people who may be on blood thinners may experience this as well. Following a regimen of tooth brushing and flossing should remove most plaque and lessen the problem of bleeding gums.
First of all, it is not your teeth that might bleed after you brush them. Teeth themselves are not able to bleed. What can often bleed after you brush your teeth is actually your gums. The most likely reason for your gums to bleed is something called periodontitis.
Periodontitis is also called gum disease. This is usually caused by inadequate oral hygiene -- not brushing or flossing enough. When a person fails to care for their teeth, plaque builds up between the teeth and gums and makes the gums tender and prone to bleeding. When such a person brushes, the gums may become irritated and bleed.
