Finger mountable dental hand piece device

A finger mountable dental hand piece device, comprising:

• a head portion and a body portion, wherein the head portion and the body portion are engaged by a flexible joint to provide flexible movement for the head portion, wherein the flexible joint is a hinge joint in the body portion;
• the head portion defines a head enclosed in a head shell, accompanied by a first finger band which is stipulated on a top of the head shell;
• and
• the body portion has a first end and a second end, the first end is to engage with the head portion, wherein the body portion has a second finger band stipulated on a top of the body portion, wherein the body portion comprises of at least three compartments, a first compartment including an air inlet pipe, a second compartment including a water inlet pipe, and a third compartment including an air exhaust pipe, wherein the body portion further delineates a reservoir sector for accommodating an extra length of the air inlet pipe, the water inlet pipe, and the air exhaust pipe, wherein the extra length of the air inlet pipe, the water inlet pipe, and the air exhaust pipe is accommodated by bending the air inlet pipe, the water inlet pipe, and the air exhaust pipe in the reservoir sector, wherein the reservoir sector facilitates bending movement of the air inlet pipe, the water inlet pipe, and the air exhaust pipe without hammering a streamline flow of air and water in the air inlet pipe, the water inlet pipe, and the air exhaust pipe, and wherein the air inlet pipe, the water inlet pipe, and the air exhaust pipe, domiciled in the reservoir sector, straighten when the head portion is stretched.
