Why are my gums hurting when i brush my teeth
Gum pain while brushing often comes from inflamed gums, plaque, brushing pressure, recession, or a local tooth problem.
The short answer
Gum pain during brushing is commonly caused by inflamed gum tissue, brushing pressure, plaque at the gumline, or a local problem such as a cavity or ulcer.
How can plaque or brushing pressure irritate the gums?
Plaque can irritate the gingiva where it meets each tooth, while a hard brush or forceful scrubbing can injure the margin. Recession may expose a sensitive root, and a cavity, crack, or ulcer can make one area hurt.
How should you brush when your gums feel sore?
Use a soft-bristled brush with small, gentle movements and clean between teeth without snapping floss into the gums. Keep the area clean, avoid tobacco, and note the exact site and triggers.
When does brushing pain need a dental examination?
Arrange an examination if pain persists, bleeding recurs, a tooth is sensitive or loose, or the gum is swollen. Facial swelling, fever, pus, or trouble swallowing or breathing requires urgent care.
Could the pain be gingivitis, decay, or brushing trauma?
Ask whether the cause is gingivitis, recession, decay, an ulcer, or brushing trauma. Ask which brush and interdental method suit your gums and whether you need cleaning or tooth treatment.
