Why can’t they make a drill without that sound?

If scientists  and engineers can design, fabricate and blast a small car-like high tech laboratory thru space and gently land it  on a tiny red planet 54.6 million kilometers away from the Earth, why can’t they make a silent dental drill?

Dentists have had access to “silent” drills for many years.  The reason why dentists use that noisy apparatus is because it works very efficiently. It blasts away dental caries and enamel very well.

A dental drill is powered by air compression. This compressed air pushes a micro turbine mounted in the head of the handpiece. This tiny turbine is pushed by the compressed air up to 200,000 RPM. That’s an incredible amount of spin action on anything that’s fixated to it; a dental bur. As the air gets tossed out from the dental drill exhaust you hear the shrill of the drill. It’s the work horse for everyday “drill and fill” dentistry.

Enamel is harder than bone. In fact,  enamel is the hardest tissue in the human body. A smooth cutting sharp diamond bur spinning at a minimum of 180,000-200,000 RPM is needed to cut away tooth structure due to enamel’s inherent durability.

On the other hand, the electric hand piece is silent. They are used for specialized procedures such as root canals and dental implant placement. Electric hand pieces produce a steady consistent slow rotation of the bur at a high torque. Higher torque tools are indicated to achieve different outcomes on tissues other than enamel, such as cementum and bone.

With that being said, next time in my office, grab one of my Bose headsets and plug into your iPhone and chill to a music playlist or book on tape. Tap the volume on extra loud and chill. It works for me!
