Gum bridge floss
Clean under a dental bridge with a floss threader, superfloss, or an interdental brush to remove plaque around the gums.
The short answer
You can clean under a dental bridge by threading floss beneath the replacement tooth and sweeping it along the gumline. A floss threader, pre-threaded bridge floss, or a suitable interdental brush can reach this space.
What is the direct answer?
What does this question mean?
A fixed bridge joins one or more artificial teeth to crowns on the neighboring abutment teeth. The underside of the artificial tooth does not touch the gum like natural enamel, so plaque and food can collect in the tunnel beneath it.
What can you do next?
Pass the threader from the cheek side to the tongue side, then use the thickened section to clean beneath the bridge and both supporting teeth. Move gently without snapping floss against the gingiva, and use an interdental brush only if it fits without force.
When should you seek dental care?
Book an examination if the gum under the bridge bleeds repeatedly, smells unpleasant, swells, or feels painful. A loose bridge, a cracked supporting tooth, or decay at a crown margin needs prompt assessment.
What should you ask the dentist?
Ask which floss or brush size fits your bridge and whether the bridge contacts are cleanable. Ask the dentist to check the margins, the supporting teeth, the bite, and the gum tissue beneath the artificial tooth.
Frequently asked questions
Can a normal toothbrush clean under a bridge?
A toothbrush cleans the outer surfaces but usually cannot reach the underside tunnel, which needs threaded floss or an interdental device.
Why does the gum under my bridge bleed?
Plaque, trapped food, an over-contoured bridge, or disease around a supporting tooth can irritate that gum.
