How to clean under a bridge
Clean under a dental bridge with a floss threader, superfloss, interdental brush, or irrigator to remove plaque around the pontic and gums.
The short answer
Clean under a dental bridge with a floss threader, superfloss, interdental brush, or irrigator to remove plaque around the pontic and gums. Slide the cleaning aid beneath the replacement tooth and sweep along both abutment teeth without forcing it into inflamed tissue.
What is the direct answer?
What does this question mean?
A fixed bridge has a replacement tooth called a pontic joined to crowns or other retainers on neighbouring abutment teeth. The underside cannot be reached by an ordinary toothbrush, so plaque can collect where the pontic meets the gum.
What can you do next?
Thread floss beneath the pontic, use a broad cleaning section to wipe each side, and finish around the gum margins. Rinse or brush the bridge afterward, and ask the dental team to demonstrate the technique if the space is tight.
When should you seek dental care?
Arrange a check if floss repeatedly shreds, the bridge moves, the gum bleeds persistently, or bad taste and odour remain after cleaning. Pain on biting can indicate a problem with an abutment tooth or the bridge fit.
What should you ask the dentist?
Ask which threader, brush size, or irrigator setting fits beneath your bridge and whether the pontic shape permits adequate cleaning. Ask how often the bridge and supporting teeth should be examined.
Frequently asked questions
Can a normal toothbrush clean under a bridge?
It cleans exposed surfaces but cannot reach the full underside, so an under-bridge aid is also needed.
Why does floss shred under my bridge?
A rough edge, tight contact, or damaged material may be catching it and should be checked.
