There is a belief that it is normal for the gums to bleed a little when brushing the teeth. It is true that a very strong brushing can cause the gums to bleed even if they are healthy. Nevertheless, The main cause of swollen and bleeding gums is periodontal disease


Gingivitis and periodontitis are the two most common gum diseases. Its most obvious consequence is the loss of teeth, but Periodontal disease affects our health in other ways, too. 

When oral hygiene is not correct, bacteria accumulate between the teeth and gums. Over time, these bacteria weaken and inflame the tissues around the tooth. This causes the gums to bleed easily.

Depending on the severity of the infection we speak of two types of periodontal disease:

  • Gingivitis. It is the most common and mildest infection. It manifests with inflammation and redness of the gums and may also have bleeding.
  • Periodontitis If no solution is given to gingivitis, this can evolve affecting the tissues that support the tooth. It usually causes pain when chewing, persistent bad breath and teeth that move.

When the infection is too advanced causes the gingiva to retract and even the loss of teeth

Although proper oral hygiene is essential to prevent these problems, periodontal disease can also have other causes:

  • Diseases such as diabetes and leukemia
  • Intake of certain medications
  • Hormonal changes during pregnancy and menopause
  • Genetic predisposition
  • Tobacco use
  • Tighter fillings


Many people with periodontal disease are not aware of it because they have no symptoms. They usually go to the dentist when they start to feel discomfort. In these cases, the infection may be very advanced, with severe bone loss. 

For this reason, it is advisable to go to the dental clinic When the first signs of danger appear:

  • Red, swollen, or tender gums
  • Bleeding when brushing teeth
  • Persistent bad breath
  • Changes in bite
  • Misfit of removable dentures

It is estimated that eight out of ten people over 35 years of age suffer from a gum problem. The best way to prevent periodontal disease is to maintain proper oral hygiene. In addition, it is convenient to carry out periodic reviews to be able to make an early diagnosis.
