My mouth is bleeding when i brush my teeth
Bleeding during brushing commonly reflects inflamed gingiva from plaque at the gum margin, although trauma, gum disease, medicines, or another oral lesion
The short answer
Bleeding during brushing commonly reflects inflamed gingiva from plaque at the gum margin, although trauma, gum disease, medicines, or another oral lesion can also be involved.
How does plaque make the gums bleed during brushing?
Plaque bacteria trigger an inflammatory response in gingival tissue, making it red, swollen, and prone to bleeding when touched. Forceful brushing, a new flossing routine, poorly fitting appliances, and some medical conditions can contribute.
What should I do when my gums bleed during brushing?
Use a soft brush with gentle small movements twice daily and clean between teeth each day. Do not stop cleaning the area solely because it bleeds, but arrange an examination if bleeding continues after improving plaque control.
When does bleeding during brushing need prompt care?
Seek prompt care for spontaneous bleeding, large swelling, pus, loose teeth, fever, unexplained bruising, or a sore that does not heal. Heavy bleeding that will not stop needs urgent help.
What should I ask about bleeding gums and plaque?
Ask whether you have gingivitis or periodontitis, whether a professional cleaning is needed, and whether medicines or general health conditions could affect bleeding.
