Bleeding gums is a common issue that affects many people, yet few understand its causes and how to prevent it. If you’ve ever wondered why do my gums bleed when brushing or eating something hard, this article will help you understand the reasons behind it and find effective solutions to keep your gums healthy.

What causes bleeding gums?
Bleeding gums should not be ignored, as it is often a sign that something is wrong with your oral health. Several causes may be behind this problem. Below, we explain the main ones.
Most common causes of gum bleeding
- Periodontal Disease
Gingivitis is the most common cause of bleeding gums. This condition is caused by the buildup of bacterial plaque that inflames the gums, leading to bleeding, swelling, and bad breath. - Aggressive or Incorrect Brushing
Using a hard-bristled toothbrush or applying too much force or having a bad technique when brushing can damage the gums, causing them to bleed. - Nutritional Deficiencies
Lack of vitamin C or K in your diet can make your gums more sensitive and prone to bleeding. - Medications
Some drugs, such as anticoagulants, can increase the likelihood of gum bleeding. - Hormonal Changes
During pregnancy or menstruation, women may experience increased sensitivity in their gums, which can lead to bleeding.
“Bleeding gums, in most cases, are related to the accumulation of bacterial plaque. It is essential to maintain good dental hygiene to avoid periodontal diseases that compromise oral health.”
Dr. Rosa Sáenz Feijoo, orthodontist and dentist.
