Seeing blood coming from your child’s mouth is one of the most frightening moments of parenthood. It happens to almost every parent at least once—more frequently for parents of more adventurous children. It can be a great relief to find that bleeding gums are the source of the blood. It may be better than missing teeth, but you should not simply ignore bleeding gums in children. Causes can range from rough brushing to bleeding disorders.

What Causes Bleeding Gums in Children?

The most common cause of children’s bleeding gums is a buildup of plaque at the gum line. The plaque leads to inflamed gums, known as gingivitis. When the gums are inflamed, they become extremely sensitive.

Brushing and flossing around inflamed gums cause them to bleed. If left untreated, the plaque around the teeth will turn into tartar that can cause gum and jaw bone disease called periodontitis. If your child’s gums bleed frequently, you should make an appointment with their dentist to reverse any damage that plaque buildup may be causing.

Gingivitis prevention

Preventing gingivitis comes down to maintaining a healthy dental routine. Brush twice daily for two minutes, use an ADA-approved toothbrush, use tartar-control toothpaste, and floss.

Flossing is the only way to remove plaque that has built up between the teeth. Monitor your children when they brush and floss to teach them the proper technique.

Other Causes of Bleeding GumsCommon Causes of Bleeding Gums

Improper brushing and flossing

If your child is brushing their teeth too hard, it will lead to swelling and bleeding in the gums. Your family should be using soft-bristled toothbrushes, but even then, rough brushing can cause damage. Flossing, when done incorrectly, can also cause some serious damage. Teach your children how to floss effectively without abusing their gums.

Diseases and disorders

Although these are less likely to be the cause of your child’s problem, there are some serious health issues that bleeding gums may point to. Bleeding gums can be a symptom of a bleeding disorder, gum infection, leukemia, and Vitamin K deficiency.
