Bleeding gums

Bleeding gums can be a sign that you have or may develop gum disease. Ongoing gum bleeding may be due to plaque buildup on the teeth. It can also be a sign of a serious medical condition.

Causes

The main cause of bleeding gums is the buildup of plaque at the gum line. This may lead to a condition called gingivitis, or inflamed gums.

Plaque that is not removed will harden into tartar. This may lead to increased bleeding and a more advanced form of gum and jaw bone disease known as periodontitis.

Other causes of bleeding gums include:

Any bleeding disorders
Brushing too hard
Hormonal changes during pregnancy
Ill-fitting dentures or other dental appliances
Improper flossing
Infection, which can be either in a tooth or the gum
Leukemia, a type of blood cancer
Scurvy, a vitamin C deficiency
Use of blood thinners
Vitamin K deficiency

Home Care

Home Care has been expanded.

Visit the dentist at least once every 6 months for plaque removal. Follow your dentist's home care instructions.

Brush your teeth gently with a soft-bristle toothbrush at least twice a day. It is best if you can brush after every meal. Also, flossing teeth twice a day can prevent plaque from building up and turning into tartar.

Your dentist may tell you to rinse with salt water or hydrogen peroxide and water, or a mouth rise designed to treat gum inflammation. Some rinses contain alcohol, so consult with your dentist prior to using one of these types.

It can help to follow a balanced, healthy diet. Try to avoid snacking between meals and cut down on the carbohydrates you eat.

Other tips to help with bleeding gums:

Have a periodontal exam.
Do not use tobacco, since it makes bleeding gums worse. Tobacco use can also mask other problems that cause bleeding of the gums.
Control gum bleeding by applying pressure directly on the gums with a gauze pad soaked in ice water.
If you have been diagnosed with a vitamin deficiency, take vitamin supplements.
Avoid aspirin unless your health care provider has recommended that you take it.
If side effects of a medicine are causing the bleeding gums, ask your provider to prescribe a different medicine. Never change your medicines without first talking to your provider.
Use an oral irrigation device on the low setting to massage your gums.
See your dentist if your dentures or other dental appliances do not fit well or are causing sore spots on your gums.
Follow your dentist's instructions on how to brush and floss so you can avoid hurting your gums.

When to Contact a Medical Professional

Consult your provider if:

The bleeding is severe or long-term (chronic)
Your gums continue to bleed even after treatment
You have other unexplained symptoms with the bleeding

What to Expect at Your Office Visit

Your dentist will examine your teeth and gums and ask you about the problem. Your dentist will also ask about your oral care habits. You may also be asked about your diet and the medicines you take.

Tests that may be performed include:

Blood studies such as a CBC (complete blood count) or blood differential
X-rays of your teeth and jawbone
