The S Bite is a soft, porous covering placed over the bite block of dental x-ray machines. It is more comfortable to bite on than just the bite block, and patients move around less thus resulting in better quality dental x-rays.
The S Bite is made of rubber silicone, and is quite soft to the touch, but durable enough that when bit upon, the underlying bite block cannot be felt at all. The S bite is easy to clean and comes in one color, light blue. S Bite is a product of the Benco company.
