Nitrous Oxide, better known as "laughing gas", is available for those who get that "anxious" feeling.

Nitrous Oxide rids you of any anxiety or fear of the procedure. You are ALWAYS conscious and you NEVER lose control. The gas is mixed with oxygen. Near the end of the procedure, the gas is reduced to a minimum, leaving only oxygen. At that point, you return to "normal" very quickly and can drive shortly after.
