Bleeding Gums


The gums act as a barrier in protecting your teeth and its underlying tissues. They act as an indicator for various underlying disease.

A healthy gum plays a vital role in preventing various diseases caused by the bacteria present in the mouth. Bleeding of gums is a highlighter for underlying irritant or bacterial activity. Frequent bleeding of gums must be taken care of immediately to prevent further progression leading to loss of bone around the tooth and thereby loss of the tooth eventually. Though bleeding gums is not a serious threat we have to make note of it to avoid any related future complaints.


  • Gingivitis ( swollen gums)
  • Smoking
  • Medication
  • Pregnancy
  • Brushing habits
  • Vitamin deficiency
  • Vitamin C

GINGIVITIS (Swollen Gums):

It is the inflammation of the gums due to bacterial activity. The gums become swollen, filled with blood and are very painful on brushing or when touched.

This occurs when hard or soft yellowish-white debris adheres to the tooth surface. These deposits act as a shelter for the bacteria to grow and multiply. These bacteria produce toxins to irritate the gums. It is the major cause of bleeding gums in adults.

The bacteria that cause gingivitis are Aggregatibacter actinomycetemcomitans, Prevotella intermedia, Porphyromonas gingivalis, Tannerella forsythia, Treponema sps.


The habit of smoking causes decreased vascularity (blood supply) to the gums. The gums of smokers appear pale, bluish, swollen and malnourished. Bleeding of gums occurs until they stop smoking and on pressure.


The use of certain medications like blood thinners (e.g: Aspirin) might cause bleeding. Patients undergoing anticoagulant therapy combined with antiplatelet drugs (e.g: Clopidogrel) show bleeding of gums. Other forms of drugs associated with swelling gums and bleeding are Antihistamines, antihypertensive, chemotherapy medication, and oral contraceptives.


Hormonal changes in pregnancy results in bleeding of gums. This is often termed as pregnancy gingivitis or inflammation of gums in pregnancy.

The hormones responsible for this are progesterone and estrogen. Progesterone increases vascular permeability i.e. the capacity of the free flow of smaller molecules. This capacity promotes the accumulation of blood in gum pockets and leads to bleeding. This hormone also reduces the ability of the tissues to repair itself. This form of gingivitis affects 60% to 75% of pregnant women.

They are observed from the second or third month of pregnancy with severity in 4th to 6th month. It gradually reduces by the last month of pregnancy. They show immediate response to any local irritants, bacterial plaque & calculus.


Reasons for bleeding of gums due to brushing:

  1.  Use of an improper toothbrush
  2. Prolonged duration of brushing
  3. Toothpaste
  4. Improper brushing techniques lead to bleeding gums.


Vitamin C: Deficiency of this vitamin causes scurvy. Scurvy leads to decreased formation and maintenance of the collagen (this collagen is responsible for the clotting of blood and repair). This causes bleeding gums followed by increasing periodontal inflammation and loss of the tooth. Pregnant, breastfeeding mothers and kids are more prone to vitamin C deficiency.

Vitamin K: This vitamin is one of the essentials in promoting clotting of blood. Deficiency of this vitamin occurs with frequent usage of antibiotics & anticoagulants (blood thinner) leading
