Abstract
Consumable abrasive-containing oral hygiene tablets are described. The tablets include glycine as an abrasive. The glycine average (Mv) particle size may be greater than 45 μm. The tablets may be used with an oral irrigator and, when placed in the irrigator's fluid flow path, may disintegrate, release the abrasive, and improve the cleaning efficacy of the irrigator.
