Swollen gums under bridge
Gums beneath a bridge can swell when plaque, trapped food, poor contour, cement, or disease affects the gum or supporting tooth..
The short answer
Gums beneath a bridge can swell when plaque, trapped food, poor contour, cement, or disease affects the gum or supporting tooth.
How does a bridge affect the gum and supporting tooth?
A bridge replaces a missing tooth with a restoration supported by neighboring teeth or implants. The tissue beneath the replacement tooth and around its supports needs cleaning, and inflammation can also arise from decay, a loose margin, periodontal disease, or an abscess.
How should you clean beneath a swollen gum and bridge?
Clean under the bridge with a floss threader, superfloss, an interdental brush, or a water flosser used as directed, and brush the gum margins gently. Do not force an instrument beneath the bridge or try to adjust it; the dentist may examine margins, take radiographs, remove deposits, repair or replace the bridge, or treat an affected tooth.
When does swelling beneath a bridge need dental care?
Arrange dental care if swelling persists, bleeds, produces a bad taste, causes pain, or makes the bridge feel loose. Seek urgent care for facial swelling, fever, pus, or difficulty breathing or swallowing.
Is the swelling caused by the bridge, gum, or tooth?
Ask whether the swelling is from plaque, the bridge margin, decay, periodontal disease, or an abscess. Ask how to clean beneath this bridge, whether its fit and contacts are correct, and whether the supporting teeth need tests or imaging.
