Laser dentistry

For some reason I got it into my head that the use of lasers in dentistry has pretty well ended the need for a drill or at least reduced its need.

So whenever I ask my dentist about the use of lasers (mainly as a way to reduce anxiety) he scoffs and says that lasers are used typically for reduction of gumline. Also that they are extremely expensive.

Does my dentist need to go back to school or what? What's the skinny on lasers in the office?
