After i floss my gums swell
Gums that swell after flossing may be irritated by technique or trapped plaque, but repeated swelling should be checked for gum disease.
The short answer
Gums that swell after flossing may be irritated by technique or trapped plaque, but repeated swelling should be checked for gum disease. Forcing floss into the tissue can cause a small injury, while established gingival inflammation can react when cleaning begins.
How should healthy flossing feel between your teeth?
Healthy flossing slides between the teeth and curves around each tooth in a C shape, without snapping into the gum. Swelling in one space may indicate impacted food, a filling edge, decay, or a periodontal pocket.
What can you do when flossing causes gum swelling?
Use a clean section of floss, guide it with your fingers, and move it gently below the contact point before hugging each tooth. If the contact is too tight, try an appropriately sized interdental brush or ask a dental professional to demonstrate the fit.
When does swelling after flossing need examination?
Arrange an examination when swelling persists, bleeding is frequent, or one site remains painful or tender. Fever, pus, facial swelling, or difficulty swallowing or breathing requires urgent assessment.
What should the dentist check at the swollen site?
Ask whether your flossing technique and contact points are suitable, and whether the site has tartar, decay, a rough restoration, or a periodontal pocket. Ask which interdental aid matches the space.
Frequently asked questions
Can flossing cause gum swelling?
Rough or forced flossing can injure tissue, while regular cleaning can reveal inflammation that was already present.
Should I keep flossing the swollen area?
Use gentle technique, but stop forcing the material and arrange an examination if the area remains swollen or painful.
