Periodontal Disease and Bleeding Gums – Causes, Treatment and Self-check


Symptoms of bleeding gums can be caused by gum disease, improper brushing, or diseases such as leukemia or myelofibrosis (bone marrow fibrosis), but most are caused by gum disease.
Children who have bleeding gums that do not stop need to see a dentist, but adults should also see a dentist as soon as possible because gum disease can lead to tooth decay and tooth loss if left untreated.

Causes of bleeding gums


Periodontal Disease (Gum Disease)

Periodontal disease is caused by an infection of the gums that destroys the gum tissue, causing the teeth to loosen and become painful. The disease is unnoticeable in the early stages and progresses rapidly if left untreated. As it progresses, it also dissolves the bone around the teeth. It is one of the causes of bad breath and is a sign that you should seek treatment as soon as possible.

Excessive brushing

In some cases, brushing with more force than necessary can damage the gums and cause them to bleed. If the same area is not brushed excessively, the gums will gradually recover in a few days.

Gum line reaching tooth decay

If the decay is large and has reached the gum line, the area will bleed due to inflammation.

Not fitting fillings

When fillings do not fit, the gums might get inflamed.

Leukemia, myelofibrosis, etc.

If there is no specific problem such as gum disease or tooth decay, it is recommended to consult an appropriate specialist as there is a possibility of blood or internal organ diseases.

Symptoms of Periodontal Disease


Periodontal disease has no symptoms in the early stages, but it progresses rapidly and by the time pain occurs, the disease may have progressed to the terminal stage. If left untreated, the disease can affect the bone that supports the teeth and lead to pain and eventually tooth loss.

Healthy Condition

The gums are clean, pink and firm, and there are no gaps – called periodontal pockets – between the teeth and gums.

Early Stage

Periodontal pockets are less than 4 mm deep, have no averse symptoms, and may be overlooked because they look like healthy teeth.

Middle Stage

Pockets are 5 mm to 7 mm deep and there still might be no symptoms. The gums are red and the teeth begin to loosen. Bleeding may be occur when the teeth are brushed.

Late Stage

The periodontal pockets are more than 8 mm deep, and as the disease progresses, the teeth loosen significantly, the gums are swollen and reddish-purple, and bleeding or yellow pus is seen when the gums are pressed.
Eating may also be painful. Please see your dentist as soon as possible as there is an increased chance that the tooth will need to be extracted.
