What Causes Bleeding Gums? 13 Possible Causes You Should Know

Bleeding gums is not often a condition that many would notice. While some might see reddish water in the sink as they rinse their mouths after brushing their teeth or flossing, they often ignore it until they feel a pain in their gums. That is when they notice that their gums are bleeding a lot.

Bleeding gums don’t hurt that much. The main problem is that there can be a slow trickle of blood until its source heals. Additionally, bleeding gums can have many potential reasons for their occurrence. Some can be harmless and don’t need any further attention. However, some underlying causes for bleeding gums can be major health concerns. Therefore, anyone experiencing bleeding gums should consider visiting a doctor or a dentist to ensure their health.

Fortunately, once someone knows the cause of bleeding gums, they can quickly resolve the issue. Here is a list of potential reasons for the bleeding gums and what can be done to stop it from happening and start the healing process.


The most common reason for bleeding gums is gingivitis. It happens when plaque is allowed to thrive in the gum line. Many people associate plaque with cavities, but they are bacteria that can infect anything close to them. If the plaque on the teeth reaches the gum line, it inflames and damages the gums. It is the first step in gum disease progression, so dealing with it early can help ensure future oral health. 

With gingivitis affecting the gums, they will be more sensitive. Sometimes, they will look puffy and inflamed. Only the most delicate brushing would not cause them to bleed. Additionally, any plaque removed will cause the gums to bleed since the hardened plaque, called tartar, covers the exposed areas. When brushing removes them, the bleeding begins. While it doesn’t seem to be a problem right now, leaving it alone will cause issues in the future. Infections can only worsen if they go without treatment, and spreading plaque and tartar will cause periodontitis.

The simplest method of dealing with gingivitis is to have a dentist do a deep cleaning of the gums and teeth. After that, start brushing regularly to prevent it from developing again.
