Additionally, Nawgum is dishwasher safe, allowing for quick and easy sanitization. Nawgum’s patented design contains four sections — two arms and two bumpers — that each feature uniquely molded textures within calculated measurements for grazing gums. The arms replicate what most children prefer to gnaw: a finger. These sections are soft and rubbery on the surface, with a slightly hardened middle, to simulate a bone. The arms are also deliberately situated in opposite directions to help the child maneuver the device.
