An oral care implement is provided having a handle and a head with tooth cleaning elements extending from fixed pods. Additional tooth cleaning elements extend from one or more central pods suspended between the fixed pods via a bridge. The bridge may be formed from an elastomer and permit the one or more central pods to move from an initial position toward the head during use. The central pods, the bridge and outer portions of the fixed pods may be formed as a unitary structure. When a single central pod is employed, a flexible section may be disposed in the middle of the central pod so that cleaning elements extending from either end of the central pod can move toward one another during use.
