Oral-B Centrays are fluoride applicator trays designed with a contoured fit.
- Stable, non-flimsy foam design keeps fluoride in the tray and moisture out
- Deep distal dam and high walls improve patient comfort and inhibit overflow
- Anatomical contours force fluoride into contact with all tooth surfaces
- Closed cell foam precludes fluoride absorption into the tray
- Rounded arch and smooth ridge provide natural fit and comfort
- Hide-a-hinge folds out of the way to help prevent gag reflex
