Bleeding from gum is suggesting that they are getting weak. Some time plaque deposited on back side of teeth also causes the bleeding. I would rethought to change your brush first. Do daily two time brush. Take vitamins c and lots of fruit juice. Avoid very warm or cold drinks. If thing does not improve show to a dentist.

Hello,

Thanks for posting on HCM,

Gums bleeding could be a sign that you are a risk of or already having a gum diseases. However, persistent gum bleeding such as you are having could be a sign of a serious underlying diseases condition which requires further medical investigation. Some common conditions that may lead to gums bleeding include:
- Periodontitis which is often accompanied by dental pain. So this will rarely be your situation.
- Gingivitis/inflammed gums
- Any bleeding disorder
- Brushing too hard
- Hormonal changes during pregnancy
- Idiopathic thrombocytopenic purpura
- Improper flossing
- Infection: Could be gingivitis or other mouth related infection
- Leukemia: Blood borne cancer
- Scurvy or severe lack of vitamin C
- Use of blood thinners: Will hardly be your cases, since I presume that you are not currently on any blood thinning medications.
- Vitamin K deficiency

In any case, you will need to see a doctor who can investigate further into the issue and provide some proper treatment.

Hope this helps
