The endotracheal tube bite block comprises two equivalent semi-circular elongated bodies partially connected to one another via linking tabs which enable the two semi-circular elongated bodies to move towards one another forming a circular elongated body to encapsulate the endotracheal tube. The endotracheal tube bite block has slope shaped design which will be placed inside the patients mouth and rest between the teeth. The endotracheal tube bite block further comprises pressure tabs which prevent complete collapse of the device under extreme biting pressures.
