A crown does not eliminate the need to clean between teeth
Yes. The crown itself cannot decay, but the natural tooth at its edge and the root below it can, and the gum around a crown reacts to plaque exactly like any other gum. The American Dental Association and the National Institute of Dental and Craniofacial Research advise cleaning between the teeth once a day with floss or another interdental cleaner, and a crowned tooth is no exception.
Where plaque collects on a crowned tooth
At the margin near the gum, at the contact with the neighbor, and under the false tooth of a bridge. Those are exactly the places a brush misses. The ADA notes that plaque left at the gum line causes gingivitis, the first stage of gum disease (ADA).
Technique
- Curve the floss around the tooth in a C shape and slide it gently just below the gum edge (NIDCR)
- If floss catches or shreds at the crown, tell your dentist; that is a clue about the edge, not a reason to stop
- Interdental brushes sized to the space work well where there is room
- Under a bridge, use a floss threader, thicker floss or an interdental brush; the Oral Health Foundation describes cleaning under bridges as essential (OHF)
- A water flosser is an addition, not a replacement, for most people
Signs to report
Bleeding that persists after a week of daily cleaning, a catch, odor, or food trapping.
Professional checks
Crowned teeth are examined and x-rayed on a schedule based on your risk, since decay at a margin is a common reason crowns are replaced.
